Initial Fracture of Carbon Fabric Reinforced Polyamide Composite

In this study, 10 types of condition were investigated. 2 types polyurethane dispersion (PUD) were applied as surface treatment of washed and non-washed carbon plain woven fabric reinforced thermosetting and thermoplastic composites. To investigate the effects of surface treatment on the mechanical properties, Dynamic mechanical analysis was employed to investigate the interfacial interaction properties. Static tensile test was used to study the mechanical properties of composites. The acoustic emission from various composites was recorded in order to investigate the initial fracture and failure mechanism.
