Deng et al. found that the strength, modulus, and creep resistance were significantly increased after incorporating UHMWPE fibers into a UHMWPE matrix, but the wear resistance of the self-reinforced UHMWPE composites could not be improved. In this paper, carbon fiber (CF) reinforced UHMWPE composites were prepared, and the effect of the CF ...

Highlights The optimum concentration of MWCNTs in UHMWPE was found to be 2 wt%. Related mechanisms for the enhancement and the reduction of mechanical properties were identified and confirmed. Formation of microvoids in nanocomposites was prominent at higher loading of MWCNTs. Variation in surface and bulk properties of nanocomposites were assessed and confirmed.

A regular Kelvin foam model was used to predict the linear thermal expansion coefficient and bulk modulus of crosslinked, closed‐cell, low‐density polyethylene (LDPE) foams from the polymer and gas properties. The materials used for the experimental measurements were crosslinked, had a uniform cell size, and were nearly isotropic.

UHMWPE has less creep than other fibers like polyester. If creep is of high concern - perhaps in the manufacture of recurve bowstrings - a UHMWPE grade with a higher modulus could be the best fit. UHMWPE also has significantly better UV resistance than aramid yarn and tends to be a better choice for outdoor applications.
