Abstract
A two phase polymer composite comprises high-modulus, continuous, pre-stressed fibers selected to maintain tension within a discontinuous fiber-reinforced polymer matrix selected to compressively restrain the pre-stressed fibers below an activation temperature. Whereas above an activation temperature the discontinuous fiber-reinforced polymer matrix is selected to cease restraint and deform to provide an external force release and dimensional change. The composite material is imparted with the characteristics of increased strength, as well as increased creep and impact resistance.
