Abstract


This is preliminary report describing results of the single fiber pull-out tests conducted with newly developed composite material based on integration of NiTi filaments into the silicon-polyester matrix. Nominal shear stress at debonding, debonding force, and spring constant characterizing fiber-matrix interface prior to a failure of the adhesion, were derived from experiments. It was concluded that current data does not support a hypothesis of rate-dependent adhesion limit and mechanical response before the debonding.

Keywords
