【 摘 要 】

Notched specimens, composed of layers of pure nylon and layers of nylon-EPR blend, were prepared. The specimens were fractured in an Izod impact test and were also fractured in tension, with the draw speed set to give a strain rate comparable to that of the Izod impact test. The data show that at these high deformation rates a brittle propagating crack can be stabilized when it reaches the ductile material (the blend).
