Abstract
Natural fiber reinforced polymer composites are widely employed in automotive, aerospace, and civil applications due to their high strength-to-weight ratios and these applications require joining composite. Bolt joining of composite materials is the most prevalent way of joining, due to its efficiency of transferring load and ease of disassembly. However, bolt joining of composite is largely influenced by geometrical parameters such as edge to diameter ratio (E/D), width to diameter ratio (W/D), and fiber orientation. This work emphases on the process parameters optimization of single lap bolt joint date palm fiber reinforced polyester composite (DPFRPC) to improve the joint strength. The study was conducted experimentally by making single lap bolt joining of DPFRPC under tensile testing. The important factors affecting the performance of the adhesively joint such as E/D (1.5, 2.5, and 3.5), W/D (2.5, 3.5, and 4.5), and fiber orientation (0/0°, 45/−45°, and 0/90°) was studied using L9orthogonal array experimental design. Artificial neural network (ANN) was used to model the experimental results. Genetic algorithm (GA) optimization technique was used to determine the optimum process parameters. Using this technique, the optimum parameters of single lap bolt joint DPFRPC were, 3.5 E/D, 4.5 W/D, and 56.5° fiber orientation, with a load carrying capacity of 9.52 kN.
