摘要

Hybrid composites have developed and demanding industrial application and replaced metals and non-metal by specific characteristics. The research work concerned with E- glass epoxy and E-glass / Kevlar 49 reinforcement epoxy. The reinforcing materials oriented at 0°/90°, 45°/45° and 30°/60° lay-up placement. The laminate was produced by hand lay-up method Vacuum Bagging Resin Transfer Molding Technique is used for air escape from the mold cavity for effective adhesion between layers of structural composites. The experimental results achieved by conducting hardness of the samples by following the ASTM standard. The ASTM D-2240 durometer was made to perform hardness over the standard samples. The water absorption characteristics of each specimen of different orientation were observed at different humidity level. Electronic weighing balance ASTM D-570 and Electronic densimeter ASTM D-792 was used for water absorption and density respectively. GFK-0°/90° (Glass fiber and Kevlar 0°/90°) has good hardness result and low density, GF 0°/90° has higher density and low water absorption and GFK 30°/60° has higher capability to absorb water than other orientations, Higher density explain the internal structure with low porous structure which has been confirmed due to low water absorption of this material.
