Effect of Healing Agent Concentration on Viscosity of Epoxythermoplastic Blend and Void Distribution of Composite Laminates
Eng-Har Lim and Kim Pickering

Abstract:
Fabrication of self-healing Carbon Fibre Fabric Reinforced Polymer (CFFRP) composite laminates were carried out by hand lay-up and density was measured via water buoyancy. The results obtained from two methods were consistent showing laminates with a higher concentration of healing agent had greater void contents. Void content was also found to be higher near the edges of laminates compared to the central areas. High viscosity of the polymer blends due to the addition of thermoplastic healing agent is suspected to be the main reason for the void distribution pattern; air bubbles entrapped in laminates during fabrication are difficult to move in viscous resin during vacuum-degassing such that eventually the movement could be halted and voids accumulate near the laminate edges. The composite laminates fabricated in this study support the potential suitability for industrial applications.
