Influence of Freeze-Thaw Aging on the Impact Performance of Damped Carbon Fiber Reinforced Plastics for Automotive Applications

The increasing use of composite materials in the automotive field requires more attention with regards to appearance noise, vibration and harshness (NVH) study cars construction. However, car door panels production, impact characteristics need be evaluated sandwich laminates. Furthermore, it is important consider effect prolonged environmental aging on crashworthiness properties. innovative content work hygrothermal effects evaluation performance for two damped CFRP In this paper, damping materials, Kraibon HHZ9578/99 SUT9609/24, were used as core between skins production. Freeze-Thaw treatment according IEC 60068, specific Automotive, was performed investigate components. Up 750 h, demonstrated that water absorption regulated by Fick’s Law. low-velocity behavior sandwiches has been studied ASTM D7136 throughout drop dart test equipment. Both main peak forces energy are negatively affected condition. introduction inside structure vehicle components can satisfy NVH constrictions. By contrast, at least same operating conditions must assured relation not-damped
