Low Velocity Impact Behaviour Analysis of Different Fibre Stacking Sequences of Glass Fibre Reinforcement Composite.

Abstract

Furthering understanding the damage deformation behaviour involved in the impact test of Fibre-reinforced composite material is important in designing for the structural components. Thus, this study presents the damage effect of different stacking sequence of glass fibre reinforce polymer (FRP) composite on low-velocity impact test (LVI). The glass FRP composites were fabricated using vacuum-assisted resin transfer moulding process, which is capable of producing constant thickness with high volume fractions of composite laminates as compared to the traditional wet hand lay-up method. The physical and impact properties were determined according to the ASTM D7137 standards. It was found that, bi-axial glass FRP composite can afford the energy until 90J and without the post perforation occurred, which mean that from the LVI test, the architecture weave of bi-axial glass FRP composite was showed high performance as compared to the unidirectional glass FRP composite. Lastly, component failures such as resin cracking, fibre breakage, fractured knit, fibre buckling, and delamination were also highlighted in this paper.
