Unlocking the potential of interleaving particle tougheners for improving the processability of composite prepreg materials

摘要

Interleaving a laminated composite with thermoplastic particles is an cost effective method to increase the interlaminar fracture toughness, which is also effective in improving the delamination resistance and damage tolerance. In typical prepregging processes, the particle tougheners are usually premixed with the uncured resin and then applied to the reinforced. This method forms a particle rich resin layer on the prepreg surface, which creates tough interlayers in the laminate after curing.
