ABSTRACT:
In accordance with a preferred embodiment of this invention there is provided a process for extruding an oriented-fiber reinforced tubular product. This product preferably is formed from a crosslinked polysiloxane elastomer produced by the curing of a fiber containing "liquid polymer" polysiloxane precursor. The subject process involves pumping the fiber containing precursor through a heated non-pumping extruder. The extruder initiates the curing reaction, shapes the reacting precursor into a tubular form and orients the fibers.
