Abstract

There is provided a flexible, low temperature, filled composite material composition and method of synthesizing the composite material composition. The composite material composition has a segmented copolymer elastomer having an α,ω-(alpha, omega)-dihydroxy terminated polysiloxane species, a diisocyanate species, and an amine or hydroxy terminated chain extender. The composite material composition further has a solid particulate filler. The composite material composition has a high flexibility at a temperature of down to about −100 degrees Celsius, has a percent elongation of greater than about 100%, and has a tensile strength of greater than about 5 MPa (megapascals).
