Abstract:

The shear properties of long-fiber reinforced composite materials can be studied on the basis of some tension tests, on the condition, for the reinforcement, to be oriented at an certain angle in respect with the load direction. The most frequently used, at this aim, are the values of 10° and ±45°. The present paper focuses on the experimental results obtained from some 10° off-axis tensile tests, on a unidirectional carbon/epoxy composite. One can consider that the resulted shear modulus values are consistent with those obtained, for the same material, using the Iosipescu shear test.

Keywords:

unidirectional composite materials, off-axis tensile test, shear modulus.
