The GO nanoparticles assisted in recovering the loss of flexural strength in the composites while improving the interlaminar fracture toughness at the same time.
Evaluating the results obtained from measurements on three types of sandstones show that the highest bending Young's modulus, as well as fracture toughness and fracture energy were found on samples from the Staric locality.
(2) the plain strain fracture toughness obtained is 136.27 MPa[square root of (m)].
