This work reports on the mechanical and wear performance of epoxy composite reinforced with short betel nut fiber (SBF). Composite samples with different weight percentages (0, 2, 3, 4, 6, and 8 wt%) of fiber content are fabricated through hand lay-up route. Mechanical properties such as tensile and flexural strengths are evaluated by conducting tests as per appropriate ASTM standards. Sliding wear tests are performed on a pin-on-disc test apparatus as per ASTM G99 standard. A non-linear regression model is developed in accordance with face-centered central composite design (FCCCD) of Response Surface Methodology (RSM). An artificial neural network (ANN) approach is applied to predict the wear rate of the composite and compared with the RSM predicted results. It is found that with the incorporation of short betel nut fiber both tensile and flexural strength of the composite shows an increasing trend. It is also observed that reinforcement of short betel nut fiber enhances the wear performance of epoxy. Surface morphologies of the worn samples have been studied to analyze the wear mechanism of the composite samples.

The recent developments and technological advancement in material science focus on the utilization of biodegradable material in various engineering applications. The increase in concern for the damages happening by synthetic materials has made the researchers develop novel materials that can reduce the use of synthetic materials to minimize the environmental problem and societal anxiety. In this work, the four‐layered areca/carbon/kevlar/carbon–kevlar hybrid fiber‐reinforced epoxy laminates were prepared by using hand layup technique for seven different stacking sequence. The prepared laminates were evaluated for mechanical, thermal, and water absorption behavior to study the hybridization effect on the properties of the composites. The result indicated that areca/carbon composites had better mechanical properties than areca/kevlar, areca/carbon–kevlar hybrid laminates. Hybridization of areca fiber with synthetic fibers had significant effect on the mechanical properties of the composites. The water absorption behavior and thermal property of the laminates improved with addition of synthetic fibers to areca fiber. Morphological analysis showed strong bonding with fibers and reinforcements, with fewer voids. Therefore, the developed areca/synthetic fiber hybrid composites can be used for semi‐structural engineering applications.

Implementation of natural fibers like kenaf in composite laminates has been the focus of many researchers. The considerable price of Low-Velocity Impact (LVI) testing, as well as the time constraints imposed by the short duration of this experiment, and prior reports of the obedience of Quasi-Static Indentation (QSI) test findings to LVI test results, have encouraged researchers to employ QSI instead of LVI. This work compares the mechanical characteristics of composite laminates consisting of chopped glass and kenaf fibers as a core and investigates the effect of hybridizing the mentioned chopped fibers as the core of a laminate. Three types of laminates with different core materials were fabricated to do this research. The results showed that among the laminates with the same weight, kenaf core laminate has the highest resistance against indentation and has the best performance in terms of absorbed energy, peak load, and damaged region. Using chopped kenaf fiber instead of chopped glass fiber can increase the absorbed energy and the peak load by 36% and 17%, respectively. Also, hybridizing the mentioned chopped fibers has not fully maximized the properties of the composite laminate during the QSI test. Finally, finite element modelling of the laminates was performed, and the numerical and experimental results were pretty aligned.
