Damage behaviors in cross-ply cloth CFRP laminates cured at different temperatures

Damage behaviors in cross-ply, [0/904]s cloth Carbon Fiber Reinforced Plastic (CFRP) laminates with different curing temperatures have been observed as a function of applied stress. Coupons manufactured by Vacuum-assisted Resin Transfer Molding (VaRTM) method with resin cured at room temperature and...
