Mar 27, 2014 . Because the reinforcing phase and matrix of the self-reinforced material have the same chemical structure, solid-state extrusion represents an effective means of achieving high-strength, high-modulus polymers at relatively low cost. In this approach, a polymer is converted to a highly oriented chain..
