pressures at reduced SoD. H-glass composites exhibited mode-I failure (large inelastic deformation) at both the SoDs, whereas E-glass composites showed mode –I failure at small SoD only. In E-glass composites, matrix cracking and fibre failure were predominant at higher SoD and insignificant at reduced SoD. However, these failure modes were not observed in H-glass composites. With the advantages of lower density, absence of matrix cracking, fibre failure and insignificant higher displacements over E-glass composites, the H-glass/composites may be a potential blast mitigating material. However, more studies are required to prove the efficiency of this material.
