AbstractThe use of sustainable, natural fiber as reinforcement for fabrication of lightweight and low cost composites is
increasingly popular in the engineering fields and it is very important to characterize their mechanical properties unde r different conditions such as varying loading speed. In this present work, the effects of strain rate on the tensile properties of basal t fiber reinforced polymer (BFRP) were investigated. These composites were fabricated hand layup with 12 layer of Basal t fiber Woven Fabric Twill with the ratio of weights of fiber is 50%. Tensile tests of BFRP specimens were conducted at two strain rates 0.1mm/s and 1mm/s using a servo-hydraulic testing system. The tensile strength and elongation increased with increasing strain rate. Moreover, tensile modulus was independent of varying of strain rate. The experiment tensile results and the finite element an alysis outcomes for BFRP agree with each other, which validates the numerical results .
