Abstract

Banana stem (Musa Acuminata, MA) fiber is a free agricultural waste obtained after harvesting the fruit. When compared to synthetic fibers, banana fiber has significant weaknesses in composite production, such as low interfacial bond strength between the fiber and the matrix. The purpose of this research is to improve the impact strength of banana stem fiber composites by adding CaCO3 powder. The hot press technique is used to create composites. In the production of polyester composites, woven MA and CaCO3 stem fibers are prepared. An impact testing machine and a scanning electron microscope were used to investigate the effect on morphological properties and impact strength. The study's findings revealed that a polyester composite containing 10% banana stem fiber and 25% CaCO3 had the highest impact strength of 45.27 KJ/m2, which was associated with strong adhesion between the CaCO3-fiber and the polyester matrix. Fiber pullout, matrix cracking, and fiber debonding were all observed in the composite fracture morphology. The resulting composite properties could be used to replace palm fiber/fiber glass composites.

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.
