Abstract:
A pultrusion article and method for manufacturing the same is disclosed. The article has a core of cured thermoset material and foaming agent. Unidirectional fibers are distributed about the periphery of the article. A shell of cured thermoset material encapsulates the unidirectional fibers, with the shell having a greater density than the core. The core and the shell are bonded together. The article provides increased strength without the use of cross-fibers.
