  • Publication number: 20120251823
    Abstract: The invention provides a tow prepreg having improved productivity and performance. In various embodiments, the tow prepreg has 90% or more resin impregnation and a FAW greater than 600 g/m2. A method of making the prepreg by impregnating each continuous reinforcement fiber strand with a thermosetting resin is also disclosed. In various embodiments, the resin is applied to the reinforcement fiber while flattening the fiber between heated rollers positioned in parallel to each other.

  • Publication number: 20120071585
    Abstract: Provided is an epoxy resin composition having superior flame resistance without containing a halogen-based flame retardant, red phosphorous or phosphate ester, and a prepreg and a fiber-reinforced composite material that use the epoxy resin composition. The epoxy resin composition has as essential components thereof (A) a phosphorous-containing epoxy resin composed of a compound (a) represented by the following formula (a), (C) a novolak-type epoxy resin, and (D) an epoxy resin curing agent. A prepreg containing the epoxy resin composition and a fiber-reinforced composite material obtained by curing the prepreg are also provided.
