SYSTEMS AND METHODS FOR MAKING INDEXED PREPREG COMPOSITE SHEETS AND LAMINATED COMPOSITE ARTICLES

摘要

A method of making an indexed prepreg composite sheet is disclosed. The method comprises forming discrete regions in a resin film layer. The discrete regions are arranged in an indexing pattern. The method also includes forming a precursor prepreg composite sheet by impregnating a fiber reinforcement with the resin film layer having a viscosity. The discrete regions of the resin film layer form non-impregnated regions of the precursor prepreg composite sheet. The method additionally includes replacing the non-impregnated regions of the precursor prepreg composite sheet with indexing openings.

1. A method (1000) of making an indexed prepreg composite sheet (300), the method comprising:
forming discrete regions (206) in a resin film layer (200), wherein the discrete regions (206) are arranged in an indexing pattern (308); forming a precursor prepreg composite sheet (301) by impregnating a fiber reinforcement (220) with the resin film layer (200) having a viscosity, wherein the discrete regions (206) of the resin film layer (200) form non-impregnated regions (310) of the precursor prepreg composite sheet (301); and replacing the non-impregnated regions (310) of the precursor prepreg composite sheet (301) with indexing openings (306).
