✦ Synopsis

The mechanical properties, the crystal orientation, and the microstructure of hot rolled and quench rolled ultrahigh molecular weight polyethylene (UHMW-PE) were investigated. The tensile strength of hot rolled and quench rolled UHMW-PE sheets increased with increasing draw ratio. The crystallographic axes a, b, and c of the rolled sheets tended to be oriented to the normal direction (ND), the traverse direction (TD), and the rolling direction (RD), respectively. The small-angle X-ray scattering patterns with incident X-ray beam parallel to TD suggested the presence of inclined lamellar structure in the RD-ND plane. At the initial stage of rolling, partial breakup of crystallites along the (100) plane was observed. The lamellar structure is deformed by the slippage mechanism along the (100) plane in the chain direction.
