Abstract
A method for fabricating long-length and/or large-sized dense filamentary reinforced monotapes. The method comprises forming a layered sandwich of matrix foils or encapsulating sheets plus foils around a reinforcing mat of collimated fibers and sealing the edges of the assembly. The sealing step is carried out with the sandwich formed to a predetermined arcuate configuration such that the sandwich can be coiled after edge sealing without buckling the encapsulating sheets or disturbing the filament alignment and orientation. The formation of the sealed, encapsulated preform can be carried out using continuous processing techniques. Subsequent processing, such as densification, can be performed with the preform in the coiled condition or after it is uncoiled to approximately the arcuate configuration of the sealing step.
