In contrast, the tensile strength of 2x2 woven composites and the tensile modulus of the UD material were insensitive to increasing strain rates. Experimental results demonstrated an increase in the tensile strength of UD CFRP composites in the longitudinal (0°) and transverse (90°) direction with increasing strain rates. DIC was used to estimate strain profiles on composites surfaces, and the modulus was calculated from those strain measurements. Tensile strength and modulus were experimentally investigated over a wide range of strain rates (0.0001 to 200 s-1). Specimen cross-sections, according to each fiber orientation tested, were consistent across strain rates to ensure results were comparable. Non-standardized specimen geometries were tested on a standard uniaxial frame and an intermediate-to-high speed dynamic testing frame, equipped with high speed cameras for 3D digital image correlation (DIC). In order to develop, integrate and implement predictive computational models for CFRP composites that link the materials design, molding process and final performance requirements to enable optimal design and manufacturing vehicle systems for this study, the dynamic mechanical response of unidirectional (UD) and 2x2 twill weave CRFP composites was characterized at deformation rates applicable to crashworthiness performance. We also ask that you refer to MatWeb's terms of use regarding this information.Īll the property values for this datasheet as they were originally entered into MatWeb.The introduction of carbon fiber reinforced polymer (CFRP) composites to structural components in lightweight automotive structures necessitates an assessment to evaluate that their crashworthiness dynamic response provides similar or higher levels of safety compared to conventional metallic structures. The resulting hybrid graphene aerogels have a high compressive strength of 56.7 kPa at 50 strain, an electrical conductivity of 3.072 S m1, and a strain-responsive electrical response sensitivity of 11.3 k Pa1 in a low-pressure range of 00.15 kPa.
