EXPERIMENTAL STUDY ON THE MECHANICAL PROPERTIES OF CONTINUOUS CARBON FIBER SHEET

Because there are so many kinds of carbon fiber sheet (CFS) with various mechanical behaviors, it is necessary and important to present a reasonable method to determine the tensile strength and modulus of elasticity for CFS. Four kinds of CFS and four kinds of epoxies were used in the test. Results show that the stress of CFS increases linearly with the increase of its strain, and that the mechanical properties of epoxy and the width of specimens will affect the tensile strength of CFS strip. The method of determining the tensile strength and modulus of elasticity for CFS is rather practicable.
