摘要

New epoxy-based composites reinforced with Prosopis Juliflora / Borassus Flabellifer (PJ/BF) fibers fabricated through hand layup technique with compression molding process were studied for their mechanical, wear properties and water absorption, as a function of weight% of PJ/BF fibers (15–45 wt%) and Tamarind seed Bio-filler (TSF) (1.5–3.5 wt%). The XRD and FTIR results verified that TSF is a lignocellulosic material. The results of the mechanical tests showed that the qualities were much improved with the addition of TSF. The flexural strength was 37.89 MPa, the impact strength was 70.28 MPa, and the tensile strength was 96.99 J/m for composites containing 15 wt% PJ/BF and 2.5 wt% TSF, respectively. Based on Taguchi’s optimization, the specific wear rate (SWR) was reduced when a 2.5 wt% TSF/15 wt% PJ/BF/6 N load was applied with an 1800 m SD. For SWR in this experiment, the results of the analysis of variance indicated that the following factors were significant: TSF, PJ/BF fiber, sliding distance, and load. A reduced coefficient of friction (COF) was seen in the mixture of 2.5 wt% TSF/15 wt% PJ/BF/6 N load/600 m SD according to the Taguchi optimized results. The SEM results showed that the wear-tested composites had surface deformations. These sustainable hybrid composites hold great potential for use in lightweight automotive parts, structural panels, and sustainable packaging materials due to their improved mechanical strength and low weight.
