  • Prediction of the Elastic Properties of Short Basalt Fiber

    Elastic Modulus The basalt short fiber may be regarded as acting efficiently if it carries a relatively high proportion of the externally applied load This results in higher strength, as well as greater stiffness, because the basalt short fiber is usually stronger, as well as stiffer, than that of a matrix Benefits of basalt fiber: In addition, fiberglass fiber has a significantly lower tensile strength, a lower modulus of elasticity, and the Poisson’s ratio indicates that it is a more fragile material than basalt fiber and steel Polypropylene fiberBasalt, metal or polypropylene fiber?
