Abstract

This study aims to analyze the mechanical strength of composites with bamboo fiber and glass powder reinforcement using an epoxy matrix. The study used a hand lay-up method with three variations of volume fraction composition, namely (1) 15% bamboo fiber, 15% glass powder, 70% resin, (2) 20% bamboo fiber, 10% glass powder, 70% resin, and (3) 25% bamboo fiber, 5% glass powder, 70% resin. The bamboo fiber used was the result of alkali treatment using 15% NaOH solution to remove lignin and cellulose, while the glass powder was obtained from household glass waste with a particle size of 60 mesh. Mechanical property testing included tensile testing (ASTM D638 Type 1), compression testing (ASTM D695-96), and impact testing (ASTM D256), while morphological structure analysis was carried out using Scanning Electron Microscope (SEM) testing. The results showed that the volume fraction composition of 25:5:70 produced the highest tensile strength with an average value of 95.69 N/mm² and the highest impact strength of 29.91 J/mm. Meanwhile, the composition of 15:15:70 obtained the highest compressive strength of 57.13 MPa. SEM analysis of the composite fracture showed the occurrence of full out fiber, debonding, and void phenomena in the matrix, which affected the decrease in the material strength value. This indicates that variations in the composition of bamboo fiber and glass powder can optimize the mechanical properties of composites, while supporting the utilization of natural materials and waste as environmentally friendly innovation materials for automotive applications, especially Yamaha Vixion motorcycle visor products.

Abstract

Structural batteries are a crucial solution in dealing with issues related to vehicle electrification to achieve energy sustainability in the future. However, the development of structural battery technology for electric-powered ships is still very limited. In particular, there are limitations in evaluating the mechanical performance of carbon fiber/polyester-PEG based composite materials for structural battery applications in electrically powered vessels. The main focus of this research is to fabricate carbon fiber/polyester-PEG to further observe the performance of its mechanical properties and structure when interacting with sea water. The value of the addition of polyethylene glycol (PEG) to the fabrication carried out was varied by 0%, 10%, and 25%. The results show that addition of 10% PEG produces a composite with the highest tensile strength, increasing the toughness of the polyester material. However, all samples experienced a decrease in tensile strength after immersion due to decreased bond performance between the fibers and seawater. The addition of 25% PEG resulted in a significant decrease in mechanical properties because high levels of PEG content made the sample easily brittle and destroyed when interacting with seawater. This research can provide initial studies on the development of carbon fiber/polyester-PEG composite materials that can be used as structural battery building materials for future electric boat applications.

Abstract

This study examines the effect of fabric architecture and alkali treatment on the properties of coconut fiber–polyester composites as an alternative environmentally friendly material. Coconut fibers were treated with 15% NaOH for 2 hours and woven in basket weave and twill weave patterns. The composites were made using a vacuum-assisted resin infusion method with a fiber fraction of 40%, and compared with E-glass composites as a control. FTIR analysis showed a decrease in the intensity of the absorption band in the range of 1200–1300 cm⁻¹, indicating a reduction in lignin content after alkali treatment. The mechanical test results showed that the basket weave composite had higher tensile and flexural strengths, respectively, of 20.40 N/mm² and 78.45 N/mm², compared to the twill weave at 12.98 N/mm² and 52.31 N/mm². However, the highest impact resistance was obtained in the twill weave at 23.61 J/mm². The results of the study indicate that the weave architecture has a significant effect on the mechanical performance of the composite and has the potential to support the development of sustainable composite materials for engineering applications.

Abstract

Natural fiber-based composites have several advantages, including relatively light weight, good strength, easy processing, and environmentally friendly. This study aims to analyze the effect of variations in the volume fraction of human hair fibers on the mechanical properties of polyester composites, including tensile strength and impact strength, as well as macro and micro morphology. The method used is an experiment with the manufacture of composite specimens using hand lay-up with variations in the volume fraction of hair fibers and dadak fibers: 15 wt%: 15 wt%, 20 wt%: 10 wt%, 25 wt%: 5 wt%. The test results show that variations in the volume fraction have a significant effect on the mechanical properties of human hair fiber composites. The highest tensile strength value of 27.7 MPa was obtained at a volume fraction variation of 25:5, while the lowest value was 23.6 MPa. In the impact test, the highest value of 0.00597 J/mm² was also obtained at a variation of 25:5, while the lowest value was 0.00482 J/mm².
