It is also found that the strength and modulus of UD composites both increased with decreasing the temperature in all cases including tensile, compressive and shear loads. On the other hand, the results show that strain to failure decreased by decreasing the temperature. Keywords: Mechanical characterization, Glass/epoxy composites, Low temperature

Jun 20, 2015· Flexural Modulus Higher flexural modulus means that the epoxy will be stiffer when higher loads push on it while under flex. Flexure modulus is very similar to tensile modulus but the sample is tested in the same way as flexural strength. Instead of testing strength along the length of the sample it is testing the strength perpendicular to the ...
