通过研制一种新的仪器，可以测量直径为5-15 μ m的单纤维的横向模量。 本文介绍了几种典型高性能纤维的横向模量和横向压缩强度的研究结果。 所研究的高性能纤维是具有不同纵向模量的芳族聚酰胺纤维、也具有不同模量值的沥青和PAN碳纤维以及一些其他参考纤维。 这些纤维在纤维轴的纵向和横向上具有很强的各向异性，并且两个方向的模量之间存在相关性。 横向强度由两个方向的模量。 还研究了这些纤维的压缩横向强度。 高度定向聚合物的有机纤维在横向压缩中显示出延展性，并具有屈服应力，但碳和陶瓷纤维在压缩中显示出脆性行为。 这些纤维的屈服应力或断裂应力和横向模量之间的相关性被发现。
The measurement of the transverse modulus of single fibres having a diameter of 5-15-mu-m has become possible by the development of a new instrument. An account is given in this paper of an investigation of some typical high-performance fibres for their transverse modulus and their fibre strength in transverse compression. The high-performance fibres studied were aramid fibres having different longitudinal moduli, pitch and PAN carbon fibres, also of different modulus values, and some other reference fibres. These fibres had strong anisotropy in the longitudinal and transverse directions to the fibre axis, and there was correlation between the two directional moduli. The transverse strength by the two directional moduli. The transverse strength by compression was also investigated for these fibres. Organic fibres of highly oriented polymers showed a ductile property in transverse compression and had a yielding stress, but carbon and ceramic fibres showed brittle behaviour in compression. A correlation between the yield stress or breaking stress and the transverse modulus was found for these fibres.
