Abstract
A metal mold is machined via a computer numerically controlled wire-cut electrical discharge technique so as to describe a fractally profiled parallel grooves-and-ridges configuration. Fibers are placed along the mold's grooves. Using the mold combined with the fibers situate in its grooves, a first composite portion is resin transfer molded so as as to describe a complementary fractally profiled parallel grooves-and-ridges configuration, and to include, in its ridges, the fibers situate in the mold's grooves. Fibers are placed along the first composite portion's grooves. Using the first composite portion combined with the fibers situate in its grooves, a second composite portion is resin transfer molded so as as to describe a complementary fractally profiled parallel grooves-and-ridges configuration, and to include, in its ridges, the fibers situate in the first composite portion's grooves, and to effect secondary bonding of the first and second composite portions.
