A prepreg composite material comprising a resin comprising a fiber layer and a thermosetting resin component, a curing agent, and fiber micropulp. The micropulp component is an aramid fiber having a volume average length of 0.01 to 100 micrometers. Prepregs are useful in composite panel structures to minimize fluid penetration into the cured structure. This prepreg is particularly suitable for producing honeycomb sandwich panels. Also disclosed are film adhesives, liquid resins and paste resins containing aramid fiber micropulp. |
