Abstract
This invention relates to extruded composite materials specifically focusing on the increasing load bearing capacity and the overall strength of composites. Injectable conformable structural core materials are used to replace foam cells inside extruded composite materials thereby increasing the overall load bearing stability and strength. The core materials are tailored to have a desired CTE with respect to the structural materials. The core materials may also incorporate fibers and solid structural fillers for increasing the strength of the composite member. The objective is to enable composite materials to have the highest structural load bearing capability possible so that these technologies can be used as the replacement of wood, in aerospace applications and for other purposes.
