Impact damage resistance of non-hybrid and intra-ply hybrid non-crimp thermoplastic composites

What is it about?

There is a growing interest in hybrid composites because of the strong need for new lightweight, high-performance and low-cost materials with improved toughness. The present study investigates the impact and post-impact properties of carbon/E-glass/PP intra-ply hybrid non-crimp thermoplastic composites. By comparing purposes, non-hybrid carbon/PP and E-glass/PP non-crimp thermoplastic composites were also tested. The intra-ply hybridization increased the compression and CAI strengths of non-crimp thermoplastic composites since the synergic efficacy of hybridization by distribution of carbon and E-glass fibers within the composite layers uniformly. The residual compression strength and modulus of impacted samples increased with hybridization which indicated to damage tolerance.

Why is it important?

In most of the studies in literature, the thermoplastic fibers are used for toughness purpose in thermoset-based composites. In addition, there are not any studies about the impact and post-impact behaviors of co-weaved carbon/E-glass/PP intra-ply hybrid thermoplastic composites.
