Summary

The effect of anodic oxidation in H2SO4 – solution on the ultimate tensile strength (Rm)and modulus of elongation (E) of carbon fibres and composites prepared from these fibres and an epoxide resin has been investigated. It has been found that this metod of carbon fibre surface modification results in an increase by 17% of the value of Rm of composites containing 20.5% by volume of fibre without changing the value of E. It has been demonstrated by changing the fibre kontent in the range of 20.5–35.5% by volume that the specifi cstrength (Rm/density ratio) and the specyfic elasticity (E/density ratio) ofa carbon-epoxide composite containing 35.5% by volume of reinforcement are higher than the corresponding values forDural.
