Technique of unidirectional composite materials at low temperatures tensile tests

The technique of unidirectional composite materials at low temperatures uniaxial tension tests. This method allows determining the tensile strength of unidirectional composite materials under normal and low temperatures. The approbation technique at low temperature of 0 °C and –30 °C. During the research all tests specimens were destroyed in the «work area», which allowed for the tensile strength and modulus of unidirectional glass fiber with 70 %. The diagrams of loading and deformation. The obtained experimental results suggest the acceptability of this method for testing of unidirectional composite materials uniaxial tension at normal and low temperatures. Recommendations of unidirectional composite materials at high temperatures test.
