Chemical ageing effects on the ply and laminate strength of a filament wound cross-ply GFRP

This work presents a numerical approach to multi-routines based on experiments, and, with a target to analyse strength of a cross-ply glass fibre reinforced plastics (GFRP) composite after immersion in sulphuric acid solution under pressure (5% H2SO4 solution, 95 °C, 15 bar). Two alternative vinyl ester resins (bisphenol A diglycidyl ether and epoxy phenol novolac) were investigated. After 0.5, 1, 1.5 and 2 years of conditioning, the specimens...
