Abstract

Three types of pressure dependent deformation processes have been observed for the short glass fiber reinforced composites of poly(vinyl chloride) (PVC). A unique deformation behavior, observed for the first time, features a sharp drop in stress followed by shear yielding in the matrix. Competitive pressure dependent failure processes in the composites are strongly affected by β€œdebonding” at the fiber‐matrix interface. A new general pressure dependent yield criterion for PVC and its composites was elucidated.

Polyacrylonitrile short fibers/ethylene-propylene-diene terpolymer rubber (PAN/EPDM) composites are prepared for the first time by mechanical mixing and subsequent vulcanization at 150 β€’ C for 50 min to substitute for composites reinforced with aramid short fibers, as thermal insulating materials.
