PREPREGGEWEBE UND WABENFÖRMIGE SANDWICHPLATTE

摘要

A woven fabric prepreg comprising at least ÄAÜ a woven fabric as reinforcing fibers, ÄBÜ a thermosetting resin or thermosetting resin composition and ÄCÜ fine particles of a resin and having a cover factor of 95% or more, and a honeycomb sandwich panel, comprising skin panels fabricated by said woven fabric prepreg and ÄDÜ a honeycomb core can be obtained. The woven fabric prepreg little changes in tackiness with the lapse of time and has moderate drapability, being excellent in self adhesiveness to the honeycomb core when used as skin panels of a honeycomb sandwich panel. Furthermore, the honeycomb sandwich panel obtained has a small porosity in the skin panels fabricated by the cured prepreg and has excellent surface smoothness with few pits and depressions on the surfaces of the skin panels.
