ABSTRACT:
Reinforcing fibers are wound onto a spool together with fibers or strips composed at least in part of a material which is to form a matrix for the reinforcing fibers. The spool is likewise at least partially constituted by such a material. After winding, the resulting assembly is placed into a container having an inner diameter which is the same or slightly larger than the outer diameter of the assembly. The container is also composed at least in part of a material which is to form a matrix for the fibers. The resulting composite blank is then placed in an induction oven and heated to a temperature which does not detrimentally affect the reinforcing fibers but which is sufficient to favorably influence the formation of reaction layers between the reinforcing fibers and the matrix material. The heated blank is compressed so as to remove any air inclusions which may remain in the interior thereof and is simultaneously deformed in a manner which enhances the flow characteristics of the blank during subsequent working. The blank is then extruded so as to form reinforced articles of the desired configuration.
