Abstract
The present invention relates to a composite article and to a process for manufacturing the composite article. The composite article comprises multiple layers including high tenacity fibers incorporated into a fabric and a core thermoplastic resin. The fabric may be coated with a surface treatment agent, a polymer matrix resin. Single or multiple layers of the composite articles may be formed into a composite part having high strength, rigidity, fast molding cycle time and extremely good conformability in a 3-dimensional mold. The composite parts formed by this process have high part strength in all directions.
Claims15
A prepreg comprising:
- a) a first layer comprising a top and bottom, wherein the first layer comprises a fabric made from high tenacity fibers coated with a surface treatment agent and a thermoplastic polymer matrix resin;
- b) a second layer comprising a top and bottom, wherein the second layer comprises a core thermoplastic resin having a higher melt temperature than the polymer matrix resin in the first layer, wherein the bottom of the first layer is adhered to the top of the second layer,
- wherein the polymer matrix resin has a melt flow index greater than the core thermoplastic resin.
