ABSTRACT:
A woven fabric gap filler with carbon fiber yarns providing a central gap filling group section of large diameter warp yarns assuming a triangular sectional shape with tab portions extending respectively from the respective apexes of the triangular filler section to be held between lay-up of opposing graphite epoxy fabric rib and flange sheets for integration therewith and to retain the apexes of the filler section against shrinkage when the assembly is heat treated. Under stress of the hard plastic structural unit, the forces will be passed through transverse fabric woof yarns as well as through longitudinal warp yarn strands so as to resist breakdown of hard plastic within the gap filling section of the structural unit when stressed.
