Fraction for fibre
WebNov 20, 2024 · By virtue of simplicity as well as less sensitivity to variation in fiber volume fraction, measurement of attenuation has been used more commonly than that of velocity in void characterization. 10 Stone and Clarke 99 noted that there is a bilinear relationship between void content and US attenuation coefficient in UD carbon FRCs, as plotted in ... WebThe fiber volume fraction is perhaps the most potent factor to affect the transverse compressive response and limit strength. To a first approximation, the composite elastic modulus in tension and compression depends only on the fiber and matrix modulus and the fiber volume fraction.
