Measurement and Research of the Transverse Mechanical Properties of High Performance Fibers
Transverse compression stress-strain curves of a single fiber having a diameter about 10 μm must be measured to obtain transverse compression mechanical properties of high performance fibers. RJY-1 thermo-mechanical analysis instrument that the smallest division value is 0.1 μm can measure the curves of the fibers by installing some auxiliary device on the instrument. The conclu- sion obtained from the features of the curve is that the Kevlar fiber showed a yielding in transverse compression, while Carbon, Ceramic and Glass fibers did not appear the yielding, and their com- pression curves were almost straight up to the point of brittleness. Transverse compression modulus, yield and breaking stress of Kevlar, Carbon and Glass fiber can be obtained from the curves.
