Effects of Fiber Layer on Failure Strength Properties of Adhesive - Joined Natural Fiber Reinforced Composites

Abstract:

This research was concerned with study of fracture strength of adhesive-lap-joined composites. The tensile and peel tests were carried out with specimens manufactured hybrid stacked composites, because the orientation of fiber and the interfacial fracture between the matrix and the reinforcement had influence on failure strength of composites. Bamboo natural fiber layer was located between polyester layers. The objective of this study was to evaluate the effect of fiber orientation on failure strength properties of composites. The test results were presented by load-displacement graph and finite element analysis. As a result, the load-directional orientation and the thinner thickness of bamboo natural fiber layer have a good effect on peel and tensile-shear strength and failure shape of adhesive-joined hybrid stacked composite.
