Abstract

Aramid nonwoven fabric was interlaminated into a Carbon Fiber-Reinforced Polymer (CFRP) composite panel by using the resin transfer molding process because of its excellent mechanical and thermal performance. The “ex situ” toughened aramid-RTM composites were demonstrated to have mechanical properties. The interlaminate fracture toughness showed a significant increase in G of 549.9 J/m2 to 1071 J/m2, and an increase in GIIC up to 58.1%, respectively. Meanwhile, the CAI value increased by 17%. The toughening mechanism was found that the aramid nonwoven fabrics still kept the original structure in the interlayer, and formed a macroscopic bicontinuous structure with the resin matrix, resulting in a remarkable toughening effect.
