Design and Manufacture of Recurve Bow Riser Using Fused Deposition Modeling and Fibre-Reinforced Composite Material

Abstract

This research redesigned and manufactured the archery recurve bow riser using Fused Deposition Modeling (FDM) system to improve its design, weight and strength. Available design of bow riser was surveyed to get inspiration for new design. Final design of the bow riser design was developed with a CAD software. Prototype of the final design of the bow riser was produced by FDM system with ABS material. Coating the prototype with carbon fibre was made. Vacuum bagging process and mechanical compression process was applied to bond the multiple layers of carbon fibre composite material. The multiple layers were tested using Universal Testing Machine to test the flexural property of the redesigned carbon fibre composite coated bow riser prototype. It is found that the multiple layer of composite can withstand up to 0.1 KN of load. Thus, the study shows that reinforcing the redesigned bow riser prototype using carbon fibre composite is suitable for it is light, easy to shape and strong properties.
