Abstract
A dual layer cured composite article is provided that has an outer part having an outer part thickness composed of a first resin matrix having between 50 and 70 total weight percent of the outer part being an outer part mixed fiber filler, the outer part mixed fiber filler having an outer part primary fiber:carbon fiber ratio of 0.05-20:1. An inner part complementary to the outer part is provided and has an inner part thickness composed of a second resin matrix having between 40 and 60 total weight percent of the inner part of an inner mixed fiber filler, the inner mixed fiber filler having an inner part primary fiber:carbon fiber ratio of less than said outer part primary fiber:carbon fiber ratio. A joinder between the outer part and the inner part is provided. A process for producing such an article is also provided.
