Effect of Fiber Orientation and Post Cure Temperature on the Flexural Strength Ply Laminate Composite

Abstract

The goal of the study is to characterize the effect of fiber orientation by using both post cured and non-post cured on the flexural strength, the material system chosen for this study is glass fiber reinforced polyester laminates of unidirectional 6-ply [0°₆],[45°₆],[90°₆] and symmetric laminates [0°/45°/90°]_s,[90°/45°/0°]_s orientations. The test procedure outlined in ASTM D790 – 17. The 3-point bending test was considered to understand the behavior of flexural strength for different oriented fibers in laminates at different post cured temperature. The results of mechanical properties for ply laminate composite are significantly improved associated with the change of fiber orientation in ply laminate and the post cure temperature. Comparing the types of ply laminates used in this study, [0°]₆ had superior advantages at post cure temperature 100^°C.
