Enhanced mechanical and tribological properties of Kevlar/PTFE‐phenolic composites by improving interfacial properties by aramid nanofibers

To gain an in‐depth understanding of improving interfacial properties of the fabric‐reinforced polymer composites, aramid nanofibers (ANFs) were constructed in situ on Kevlar and PTFE fiber surface to promote the mechanical and tribologic properties of Kevlar/PTFE‐phenolic composites. Through rich interactions between in situ ANFs and the phenolic matrix, the interfacial characteristics of the inert and smooth functional fibers contained in the...
