NON-HOOK CHATACTERISTICS OF TENSILE MODULUS OF CARBON FIBERS
碳纤维抗拉模量的非虎克特性

The modulus-strain curves of two kinds of PAN-based and one kind ofisotropic pitch-based carbon fibers were measured in this paper.It was discovered that themoduli of three kinds of carbon fibers do not always change linearly with the strain.Each curvecan
