摘要

The primaryscope of the research is to develop and investigate the properties and performance of the composites as a uniquetactic in the material science field. This research investigates the mechanical, thermal, and machinability properties of an epoxy composite reinforced with basalt and bamboo fibers, incorporating varying concentrations of chitin. The optimized composite, EBT3 (4 vol% chitin), demonstrated superior load-bearing capacity, with fatigue life counts of 24,711, 21,711, and 18,741 cycles at 25%, 50%, and 75% UTS, respectively. Additionally, its creep behaviour exhibited minimal deformation, with values of 0.0064, 0.0069, and 0.0095 at 5,000, 10,000, and 15,000 s, indicating enhanced adhesion and interfacial bonding. In contrast, the EBT4 composite (8 vol% chitin) exhibited reduced flame propagation speed (5.31 mm/min), moderate hydrophobicity (67.52° water contact angle), and improved machinability, as evidenced by narrower kerf widths of 5.06 mm and 10.09 mm for 5 mm and 10 mm drill bits, respectively. The higher chitin content contributed to increased hydrophilicity, enhanced structural integrity, and greater thermal stability, influencing these properties. SEM analysis further provided insights into fiber-matrix bonding, filler dispersion, and agglomeration effects. Given their exceptional properties, these composites hold potential for marine, prosthetic, drone, automotive, and packaging applications.
