The yield stress of polyacetal (POM) decreases monotonically with the incorporation of thermoplastic polyurethane (TPU) elastomer in POM/TPU blends as would be anticipated. However, the impact strength of the resultant POM/TPU blends increases initially up to 30% TPU and thereafter decreases with th
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
## Abstract This article discusses the viscoelastic behavior of a vinyl ester (Derakane 411β350) reinforced with 1.25 and 2.5 wt % nanoclay and exfoliated graphite nanoplatelets during shortβterm creep and relaxation tests with a dynamic mechanical analyzer. Linear viscoelastic models are generally
