Stress relaxation behavior of short Kevlar fiber-reinforced thermoplastic polyurethane ( T P U ) is studied with respect to strain level, strain rate, fiber loading, and fiber orientation and temperature. The existence of a two-step relaxation mechanism for unfilled stock and a three-stage relaxatio

Unidirectional composite laminates based on carbon fibers (CF) and highperformance polyethylene fibers (PEF) and their hybrids were prepared with partially polymerized methyl methacrylate (MMA) at room temperature, followed by heating at 55ΠC (well below the softening point of PEF, 147ΠC) for 2 h.

## Abstract Wool is a natural keratin fiber made up of cuticle and cortical cells held together by the cell membrane complex (CMC), which contains few internal lipids (IWLs) (1.5% by mass). IWL arouse considerable cosmetic and dermatological interest because of its high proportion of ceramides. In
