Effect of Laminate Configurations on Impact Properties of GFRP Composite in Seawater

Abstract:

Article Preview

Hybrid laminates of glass fibre reinforced plastics (GFRP) are being increasingly used for marine structures under multidirectional loadings, due to their anisotropic behavior, corrosion resistance, high specific strength and stiffness. Therefore appropriate laminate configuration for marine environment applications is an important field of study. Five types of fibre epoxy laminates configurations, resulting from different combinations of three layers of chopped strand mats (CSM) and woven roving (WR) were fabricated using the vacuum resin transfer moulding (VRTM) technique. These were investigated for the effect of seawater on its impact properties. The results showed a significant reduction in the impact strength in all types of wet specimens. This behavior may be attributed to penetration of water molecules in the composites. The impact properties of hybrid laminates using a mixture of CSM and WR were found to be better than combination of laminates comprising only CSM and WR under both dry and wet conditions for marine structure.
