Abstract
In order to analyze the creep properties of UHMWPE multifilament and aramid multifilament, four-element model and Matlab software were used to get creep fitting curve, the corresponding mechanical fitting equation and microscopic parameters. The creep properties of the two kinds of multifilament were discussed by microscopic parameters. At the same time, the tensile and relaxation performance of UHMWPE multifilament and aramid filament were studied. Compared with aramid multifilament, UHMWPE multifilament has higher strength, better elongation, lower creep resistance and obvious the phenomenon of stress relaxation. This article will provide some basic performance reference to the application of UHMWPE multifilament.
