Abstract

Plastic composite boards are made from OP-EFB (oil palm empty fruit bunches) which function as a filler, while HDPE (high-density polyethylene) plastic is used as a matrix. This study was conducted to analyze the physical and mechanical properties of plastic composite boards from empty palm oil bunches and high-density polyethylene plastic based on the effect of pressing temperature and determine the optimum pressing temperature. The temperature used for pressing were 140 oC, 150 oC, 160 oC, 170 oC, and 180 oC with the addition of coupling agents of MAH (maleic anhydride) and BPO (benzoyl peroxide) initiator. Based on the research that has been carried out, the physical and mechanical properties of the resulting plastic composite board are affected by differences in pressing temperature, with an optimum temperature of 170 oC the results of the testing were density, water absorption, MOR (modulus of rupture) compressive strength parallel to the surface and compressive strength perpendicular to the surface were 0.950 g/cm3, 0.090 %, 134.40 kg/cm², 465.80 kg/cm², and 50.40 kg/cm² respectively and the average test results for all treatments were 0.88 g/cm³, 1.00%, 130.20 kg/cm² and 426.96 kg/cm² respectively. The mechanical physical properties of plastic composites meet SNI 8154-2015 standard on WPC (wood plastic composites), except for MOR and perpendicular compressive constancy of the surface.

Abstract

This research is based on the importance of finding crosslinking agents that are environmentally friendly and able to improve the performance of the interfacial area between natural fibers and their polymer matrix. Poly(lactic acid) PLA composites containing 20 wt.% abaca (Musa Textilis) fibers were manufactured by injection molding. The composite specimens contained surface-modified abaca fibers with 5 wt.% glutaraldehyde (GA) as a cross-linking agent were examined in this experiment. The SEM was applied to assess the morphological surface of the abaca fibers, while FTIR analysis was performed to investigate the chemical components of abaca fibers. The mechanical characteristics of the PLA/Abaca fiber biocomposites were examined using flexural, tensile, and Izod impact tests. The results confirmed that the modulus of elasticity and Young’s modulus were observed to increase by 40% and 37% respectively. Meanwhile the tensile strength and the flexural strength increased by 26% and 15% respectively. PLA/Abaca fiber biocomposite that had been treated with glutaraldehyde had better mechanical qualities than pure PLA biocomposite.

Abstract

Natural fibers are progressively employed in manufacturing polymer composite structures beneficial to automotive, construction, and aerospace industries. The upsurge in the utilization of natural fibers in various industries is ascribed to enhanced awareness of the toxicity of man-made fibers. It is imperative to preserve the ecosystem. Thus, legislators and investigators are brainstorming on substituting conventional materials with earth-friendly resources. Natural fibers are green resources with multifarious advantages over synthetic materials, including ease of processing, reduction of CO2 effusions, biodegradable, recyclable, acceptable thermomechanical attributes and improved compatibility with human health. Therefore, natural fibers are widely applied as modifiers for polymers. Recently, natural fibers reinforced polymeric composites, bio-composites and bionanocomposites are the hot potato of researchers ascribed to their attributes such as having low specific gravity, producing good results without costing a lot of money, earth-friendly, and sustainable among others. Jute, kenaf, coir, and hemp natural fibers derived from plants can be exploited to achieve novel lofty execution polymer composite systems. Thermo-mechanical behavior of natural fiber-reinforced composites, bio-composites and bionanocomposites including stress-strain, bending, failure resistance, impact toughness, temperature and deformation fashion them to be more sustainable and engaging than man-made fibers with exceptional biodegradable hallmark. Thermomechanical analysis (TMA) determines variations in specimen dimensions with varying temperature, time or load at ambient conditions. However, TMA of natural fiber-reinforced polymer composites is limited. Therefore, the review highlights on natural fiber-reinforced polymer composites, bio-composites, bionanocomposites, their crucial thermo-mechanical attributes, and emerging implementations.

Abstract

In recent decades, ultra-high molecular weight polyethylene (UHMWPE) has gained recognition and widespread utilization as an outstanding polymeric biomaterial for load-bearing components in artificial joints. Despite its promise, this material presents challenges in processing with additive manufacturing techniques. Efforts have been underway to investigate and enhance its printability with the additive manufacturing, aiming to facilitate the production of patient-specific implants. This study aims to prepare UHMWPE-based filament through extrusion and subsequently print it with fused filament fabrication (FFF) 3-dimensional (3D) printer to create a simple rectangular sheet. Characterizations by using Fourier-transform infra-red (FTIR) spectroscopy and differential scanning calorimetry (DSC) were conducted to assess the chemical compositions and thermal properties of the UHMWPE filament and its printed forms. The findings of this research demonstrate the feasibility of printing UHMWPE filament filament within the temperature range of 200 - 240 °C. Analysis of the FTIR and DSC spectra reveals no evidence of impurities introduced during the preparation and printing processes that could alter its properties.

Abstract

Researchers are interested in investigating the optimum features of Sesbania grandiflora fibers (SGs) and Leucaena leucocephala fibers (LLs) for application in a wide range of applications. The purpose of this study was to explore the effects of NaOH and bleaching on the chemical characteristics, density, moisture content, and functional groups of sesbania g. and leucaena l. fibers. SGs and LLs fibers were chemically changed in various ways, including alkalization with 5% NaOH for 2 hours and bleaching with sodium chlorite (NaClO2) and acetic acid (CH3COOH). The results of the study showed that the cellulose, lignin, and hemicellulose content of the modified fiber was generally lower than that of the raw fiber. This was explained by the hydrolytic agents NaOH and bleaching causing damage to the cellulose chains and bond modifications. It was discovered that NaOH treatment was more effective at removing lignin and hemicellulose components in addition to cellulose, based on the functional groups seen in FTIR spectra. After the alkali and bleaching processes, the water content of SGs/NaOH, LLs/NaOH, SGs/bleaching, and LLs/bleaching fibers was reduced to 5.4 ± 0.89 %, 6.23 ± 0.87 %, 7.12 ± 1.02 %, dan 0.22 ± 0.21 %, respectively. This is also because the fiber has a relatively high fiber density of between 0.2 and 0.3 g/cm3, which is caused by the loss of non-fiber substances that are linked to the fiber. The results show that PFs treated with bleaching, NaOH, and raw fibers have the potential to be used as fillers in biocomposites and as substitute materials for glass fiber in the textile industry.

Abstract

The present study was carried out to develop composites using waste castor bean shell (CBS) as a filler and epoxy resin as a matrix. The composites were produced by varying the weight fractions of filler in the range of 5 to 35 wt%. The effects of castor bean shell filler weight percentages (0, 5, 10, 15, 20, 25, 30 and 35) on the tensile, flexural, impact and hardness properties of the epoxy/castor bean shell composites were evaluated using universal testing machine, hardness tester and scanning electron microscopy (SEM). The study revealed that the tensile strength, tensile modulus, flexural strength and impact strength increased with the increasing of the castor bean shell filler content. The highest tensile, flexural and impact properties of the CBS loaded epoxy composite were achieved at a filler content of 15wt%. The hardness increased with the increasing of the castor bean shell filler content. The water absorption and the thickness swelling increased with the increasing of the castor bean shell filler content. The swelling rates of the castor bean shell-epoxy polymer matrix composites are low during the initial stages of moisture absorption due to the visco-elasticity of the polymer matrix. The density decreased with the increasing of the castor bean shell filler content. SEM showed improved interfacial adhesion of the castor bean shell filler-epoxy resin matrix at 15wt% CBS content. The study has shown that castor bean shell filler is a viable reinforcement for manufacturing green composites from the viewpoint of their physical and mechanical properties.

Abstract

The paper is to reveal the bacterial cellulose powder as a filler for a composite matrix with an oil palm trunk. The use of oil palm trunks is excellent because of their abundant availability and because they can reduce waste. It is low-density, environmentally friendly, inexpensive, non-toxic, and easily degraded as a matrix that produces hydrogels obtained from cross-linking. This research is a laboratory experiment that makes films by masks using the bacterial cellulose powder obtained through enzyme hydrolysis fillers with the addition of 1%, 2%, 3%, 4%, and 5%. Bio-composite films are readily biodegradable, so the films made from extracting oil palm trunks with stem starch are environmentally friendly. The pH value of the five preparations for film gel masks was the shelf life of bio-composite, which could last for 21 days. Characterization of film masks includes physical properties and analysis of chemical composition, where the amount of water in the film will decrease as the size of the polymer that makes up the film matrix increases. The treatment that produced bio-composite films with the best mechanical properties under the addition of bacterial cellulose powder was 3% filler. The cellulose bacterium can be applied as a filler for making composites by modifying the oil palm trunk as a matrix composite.

Abstract

Blending of biopolymers with other polymers i.e. PVP (polyvinylpyrrolidone) is expected to improve the processability and properties of biopolymer-based films. This blending leads to the new molecular structures due to interactions between the polymers, which affect the crystallinity and morphology of the films, as results, enhance the mechanical, optical, and thermal properties of the biopolymer/PVP films. This review aims to provide an overview of the effect of PVP on the molecular interactions, crystallinity, and morphology of biopolymer films. such as chitosan, ethyl cellulose (EC), hydroxyethyl cellulose (HEC), and hydroxypropyl methylcellulose (HPMC). PVP can form hydrogen bonds with chitosan, HEC, and HPMC. Incorporating PVP with HPMC and HEC results in a uniform film morphology, whereas higher PVP ratios in chitosan/PVP blends can cause cracks, indicating the necessity for an optimal ratio to achieve a homogeneous matrix. The addition of PVP to EC results in discoidal features within the film matrix, signifying separate phases and immiscibility between PVP and EC. PVP also able to disrupts the semicrystalline structure of HEC and HPMC, making the film more amorphous.

Abstract

Natural fibers, including both animal and plant fibers, have many applications in a variety of sectors, therefore knowing the effects of chemical treatments on their characteristics is critical. This study evaluates the impact of different chemical treatments, including silanes, acetylation, benzoylation, peroxides, and several coupling agents, including maleation. In addition, this paper discusses treatment using acrylation and acrylonitrile, stearic acid, sodium chlorite, oleoyl chloride, isocyanate, and permanganate. These treatments alter the surface structure of the fibers by changing their chemical composition and shape. Silane and coupling maleation chemicals typically increase fiber attachment to the polymer matrix, whereas acetylation and benzoylation frequently improve resistance to moisture and microbial attacks. Peroxide and permanganate can produce oxidation, which reduces fiber strength, but grafting acrylation, acrylonitrile, and isocyanate improves resistance and temperature stability. Stearic acid and oleoyl chloride increase hydrophobicity, whereas sodium chlorite treatment alters the lignocellulose structure, increasing density and strength. This study also examines the impacts of biological treatment with fungi, that may change fiber structure via biodegradation pathways. This study's findings shed light on how various chemical treatments might alter the durability and strength of natural fibers, and also their use in industry and material technology.
