Abstract
Reinforcement preforms and methods for making same for use in fiber-reinforced composite materials structures are disclosed, in which the reinforcement preforms comprise first and second reinforcement preform elements which include strength reinforcement fibers that are in desired directional orientation. The first element has a cross-fiber surface which extends transverse of its constituent strength reinforcement fibers and is in contacting juxtaposition to a selected surface region of the second element, forming an abutment therebetween. Abutment strength reinforcing fibers, which may optionally be introduced in situ by a continuum of fibers, such as a yarn or thread, extend through at least a portion of said second element and its said selected surface region, the abutment, said cross-fiber edge surface, and into the first element substantially in the direction of orientation to its constituent strength fibers to which its cross-fiber surface is transverse.
