  1. Tensile tests of carbon filament yarn shows at high strain rate that the mechanical behavior of carbon fiber bundles are insensitive to strain rate, i. e., the failure stress strain and elastic modulus are not increased with the rising of strain - rate. however, the fractograph of carbon fiber is rate - dependent. the fractograph of carbon will become smooth from coarse as the strain rate increases

    通過對碳纖維束的沖擊拉伸試驗表明,雖然碳纖維束的力學性能與應變率基本上是不相關的,即隨著應變率的增大,碳纖維束的初始模量、破壞應力及其失效應變都變化不大,但碳纖維束的破壞斷口與沖擊拉伸實驗的應變率密切相關。
