Cyclic Olefin Copolymer Interleaves for Thermally Mendable Carbon/Epoxy Laminates
Molecules, 2020 Thin cyclic olefin copolymer (COC) foils were used as intrinsic thermoplastic healing agents in carbon fiber (CF)-reinforced epoxy laminates. COC films were produced by hot pressing and were interleaved in the interlaminar regions between each EP/CF ...

Polymer Composites, EarlyView.Helical wrapping of polyamide around E‐glass fibres deflects and bridges impact‐driven cracks, arresting damage that would otherwise propagate catastrophically in conventional side‐by‐side hybrid yarns. ABSTRACT Hybrid cowrapped (CW) yarns were engineered to enhance the impact resistance and damage tolerance of fiber‐reinforced composites.

Polymer Composites, EarlyView.Veil interlayers of five different chemistries (PI, FG, PPS, PEI, PEEK) were placed at two through‐thickness positions in carbon and glass fiber/epoxy laminates and evaluated under interlaminar shear (ILSS), three‐point bending (3PB) and axial buckling loading. The optimum placement was found to be loading mode dependent: near‐surface placement favored
