4 test principle
The tensile strength and tensile modulus of the continuous SiC fiber bundle are determined by stretching the fiber bundle after the impregnated resin is cured
Damage to determine. The tensile strength is obtained from the breaking load divided by the cross-sectional area of the continuous SiC fiber bundle, and the tensile modulus of elasticity is the amount of change in stress
And the corresponding strain change ratio. Elongation at break is the ratio of the elongation at elongation to the gauge length at beam load loading up to the maximum load.
