ABSTRACT:
A composite article is made by braiding a 3D article shaped preform including non-fugative braider reinforcing fibers and fugative fibers and removing the fugative fibers to form a plurality of matrix-ingress passages in the braided preform. During impregnation of the braided preform with a matrix material, matrix material is supplied to the interior of the preform via the passages. The fugative fibers typically comprise fugative monofilaments which are substantially larger in size than the non-fugative fibers to permit one or more dimensions of the preform and thus the composite article to be increased beyond the capacity of the particular braiding apparatus employed.
