A Review on the Methods of Interlaminar Properties Using Nanomaterials to Reinforce Carbon Fiber Epoxy Composites

Abstract

Carbon fiber reinforced epoxy composites is playing a role in reducing structural weight and costs, saving resources and optimizing processes. However, the low properties of epoxy matrix and the weak interfacial bonding between carbon fiber and epoxy lead to the poor interlaminar performancec for carbon fiber or fabric reinforced epoxy composites. The application of nanomaterials is an effective way to improve or enhance the interlaminar properties of composite materials. Therefore, this paper summarized the research on the methods of nanomaterialsto reinforce resin matrix, and nanomaterials-carbon fibers multi-scale reinforcement to enhance the interlaminar performace, and nanomaterials to distribute the surface of prepreg uniformly, and nanomaterials to promote interfacial binding energy between carbon fiber and epoxy and nanomaterials macrostructure to improve the interlaminar properties of composites.

Rubbery-Modified CFRPs with Improved Mode I Fracture Toughness: Effect of Nanofibrous Mat Grammage and Positioning on Tanδ Behaviour

“…Nanofibrous mat interleaving is a simple and smart approach: it can be virtually applied to any commercial prepreg during lamination, without the need for preliminary resin modification [20,21]. Nanofibrous nonwovens can be applied to composites for enhancing mechanical performance, mainly interlaminar fracture toughness [22][23][24][25][26][27], or adding new properties [28,29].…”
