Crack Healing in Polymers.
Abstract
The healing of cracks, crazes, voids and mechanical energy losses were studied in a variety of polymer materials. These included amorphous, crystalline, crosslinked polymers, block copolymers and both rigid and soft composites. Mechanical testing methods consisted of uniaxial tension, wedge cleavage, compact tension, fracture, lap shear joint fracture, single edge notch fracture, Izod impact and compact tension fatigue. The important problem to solve was that of strength development, sigma, at a polymer-polymer interface as a function of time, t, temperature, T, pressure, P, and molecular weight, M.
