Mechanical Characterization of 3D Woven Carbon Composite

Abstract

This report presents the results of testing performed by Intertek on six 3D woven carbon fiber composites. The panels were woven by 3Tex and Textile Engineering and Manufacturing (TEAM). Vacuum Assisted Resin Transfer Molding (VARTM) was performed by the University of Delawares Center for Composite Materials. Tensile tests were conducted along all three axis, and shear tests were performed on the x and y axis. The Ultimate Tensile Strength (UTS), Youngs Modulus, Shear Modulus, and Poissons Ratio were calculated for each panel. Each panel showed varying degrees of anisotropy, which is typical for composites. This was particularly notable along the z-axis. The quantitative results for the majority of the tests are suspect and should not be considered accurate. This is due to grip slippage and adhesive failure that occurred during the tensile tests. As a result, further characterization of these materials will be necessary.
