Composite structural part formed of multiple layer fibrous preforms inter-fitted with one another and reinforced with a polymer matrix coating

摘要

A composite part including a fibrous assembly including at least two preforms each of which includes layers of fibrous cloths. Each preform includes at least one opening or protruding structure which is substantially complementary to the structure of the other preform. The first and second preforms are engagement with one another and are firmly connected by a polymer matrix being injected around the preforms.
