Abstract

The mechanical properties and fracture mode of polymer composite materials reinforced with fibers of high-performance polyethylene are investigated. It is found that plasma treatment (activation) of the fibers increases the composite strength. This effect is explained by the formation of chemically active centers on the surface of treated fibers, the strength of the fiber-matrix joints in which is higher. These centers can be seen through an optical microscope as white stripes. The changes observed are connected with a unique fibril-porous structure of the fibers as well as peculiarities of cross-cut craze propagation throughout the fibers.
