Fractographic Analysis of Unidirectional Carbon Fiber Reinforced Plastic (CFRP) Composite Laminates Failed under Compression Loads

Abstract

This paper describes fractographic features observed in unidirectional CFRP laminates failed under compression loads. The morphology of fracture surfaces was studied using scanning electron microscope. Typical fracture modes are presented. It has been demonstrated that macroscopy coupled with fractography yield useful data from which correlation of macro/microscopic details with loading conditions could be established. Detailed study was conducted to map the crack propagation direction
