Experimental Research of Automotive Needlepunched Carpets at Thermoforming Temperatures
摘要
Abstract
Tensile prerties with different thermoformingconditions and deformation mechanism at thermoformingtemperatures of automotive needlepunched carpets made up ofthree layers of different materials were reported.Investigations on the tensile properties were performed as afunction of thermoforming temperature, extensile speed andfiber orientation based on an orthogonal experiment design.The experimental results show that the automotive carpets arerate-dependent anisotropic one and very sensitive to theforming temperature. The tensile properties are stronglydepended an the forming temperature when compared with theextensile speed and the fiber orientation. Experiments onlyvarying with the temperature were performed because of thedominative effect of the temperature. Different defotmationperformances were observed with different temperatures.Deformation mechanisms at the thermoforming temperatureswere presented to explain the nonlinear trend of the ultimateelongation with the temperatures based on the combination ofthe experimental observations and the corresponding polymertheories.关键词
