Experimental Investigation on Drop in Tensile Performance Index of Carbon Fiber Composite in Use
To investigate the causations why the tensile performance index of carbon fiber composite in use is generally under that offered by the manufacturer, the tests on the tensile characteristics of the carbon fiber monolayer and those of the gumming carbon fiber monolayer were carried out in this paper. Based on the test results and mixed principle of the relation between strength of composite and each of the components, the influencing factors on the drop in tensile performance index of the carbon fiber composite in use were analyzed. It is concluded that all kinds of the defects could reduce the local strength of composite materials. Internal defects of the composite, possible load eccentricity in the test, size effect of the composite sample, and tensile properties of the resin may be the primary influencing factors.
