Tensile Creep Behavior of PP/CF Wet-Laid Nonwoven Composite: Short-Term and Long-Term Creep Behavior
Source abstract
Abstract
PP/CF wet-laid nonwoven composites have potential application in automotive secondary structural parts, but their long-term service behavior needs clarification. This paper investigated the effect of CF content, load, and interfacial enhancement on short-term creep behavior of the composite and plotted a master creep curve to study the long-term creep behavior. Short-term tests showed that creep resistance peaked at 30 vol% CF, higher loads reduced resistance, and interfacial enhancement improved it. The Findley and Burgers models fitted short-term curves well, with Burgers parameters reflecting intrinsic creep behavior. Creep master curves (reference temperature of 30 °C) of 30 vol% CF composites showed no rupture, indicating good long-term creep performance.
