Abstract
In the present study varying thickness of (5-25mm) E-glass composite laminates have been prepared through hot compression moulding method using different matrix systems such as phenolic and epoxy with E-glass fiber as a common reinforcement. The laminates were initially evaluated for their mechanical and mode-I inter laminar fracture energy as per ASTM test methods. It is observed that the laminate having epoxy matrix has shown higher mechanical and fracture energy than the laminate made using phenolic matrix. This is due to the strong adhesion bond between the epoxy matrix and glass fiber reinforcement. Further, the laminates were subjected to ballistic impact tests against 7.62X 39 mild steel projectiles. It is observed that the laminate having lower fracture energy (E-glass/phenolic) has shown better energy absorption under ballistic impact. Failure analysis on post impacted laminates have been studied using C-scan analysis and observed that E-glass/epoxy composite laminate has shown limited damage area, whereas E-glass/phenolic composite laminate has shown more damage area. This study reveals that the laminate having lower fracture energy for delamination is more suitable for higher energy absorption due to dissipation of energy in lateral directions under ballistic impact conditions.
