Abstract

Abstract. The modification of the characteristics of natural fiber composites with components derived from abundant and environmentally beneficial horse dung waste has piqued interest. The purpose of this investigation was to see how adding horse dung particles (DN) to pineapple leaf fiber (DN)/polyester composites affected the results. To create new samples, different percentages of HF (5–30%) are utilized. Hand-layup method was used to create the DN/HF composite. The results revealed that adding 30% (vol. percent) HF to the composite improved elongation, flexural strength, and flexural modulus, while adding 5% (vol. percent) HF improved impact strength, tensile strength, and tensile modulus of elasticity. At 30% HF concentration, maximum flexural strength values of 63.91 5.1 MPa were recorded. The composite's fracture morphology revealed weak interfacial interactions between DN-polyester-HF, and particle accumulation.

Abstract

The purpose of this study was to look into the performance of a cornhusk fiber (CHF) reinforced polyester composite with pumice powder (PP) as a filler. The influence of varied PP volume fractions on composite tensile, bending, impact, and fracture morphology was studied. Using the hot press process, polyester-CHF composites with varied volume fractions of PP filler, namely 5%, 10%, 15%, 20%, 25%, and 30% wt, were created. The results showed that increasing the PP volume fraction from 5% to 15% enhanced the tensile strength of the polyester-CHF composite. The modulus of elasticity and bending modulus tend to grow when filler Pp decreases from 5% to 30%, but elongation value decreases. Furthermore, the best bending strength and impact toughness of the polyester-CHF composite were produced at a volume fraction of PP filler of 20%. SEM images indicate the presence of CHF pull out in all composite variations as well as the number of voids dependent on the PP filler volume.

Abstract

In this study, composites made from water hyacinth powder (WPH) and rice husk powder (RH) were created using the hot press method, and the composites were characterized to determine their suitability for biomedical applications such as tissue engineering. The mixing ratio of WPH/RH was investigated. Fourier transmission infrared spectroscopy (FTIR) revealed the presence of chemical bonds in the composites under investigation. Tensile tests were used to investigate the mechanical properties of the composite, which revealed that adding water WPH to the rice husk composite reduced the composite's strength. A composite with a 5% WPH content had the highest tensile strength of 32.72 MPa. Meanwhile, the mechanical strength of the other composites studied ranged from 25,537 MPa to 29.43 MPa. However, the elastic modulus of the composite increased with the addition of WPH. The SEM image shows that the powder distribution is less even, the interface between WPH-RH and polyester is quite tight, and the composite contains a number of voids. Characterization of the developed composite demonstrates that the WPH/RH addition ratio can be adjusted to achieve the desired composite properties for tissue engineering and cartilage regeneration applications.
