Filament wound flat strip composites of polyethylene fiber reinforced polyolefins arepresented and studied. The versatility of this product is demonstrated by involving different polyolefin compositions based on ethylene-butene copolymers with a range of fiber volume fractions and various winding angles. The mechanical performance of the composite product agrees with standard theoretical predictions for angle-ply composites, while the dynamic mechanical analysis reflects the viscoelastic nature of the matrix. In particular, the branching density of the polyolefin backbone, expressed by the β-transition peak, dominates the dynamic mechanical behavior. The feasibility of a potential biomedical application is discussed based on process variable optimization, resulting in a specific combination of static and viscoelastic properties.
