摘要：
The Vickers microhardness test has been carried out on GFRP specimens at different loads ranging from 5 to 160 g. The Vickers hardness number (H(v))-load behaviour has been explained on the basis of strain hardening phenomena. This reveals that the value of H(v) is greater at small stresses and it becomes independent of load beyond 110 g. In this range the value of the logarithmic index, n, is 2. The non-linear behaviour of microhardness with load has three different values of logarithmic index. Further, the dependence of load on H(v) in GFRP specimens has been explained on the basis of Newtonian resistance pressure as proposed by Hays and Kendall.
