Abstract
This work aimed to investigate the strain-rate effect (0.001-3000Â sâ1) on compressive properties of the highly cross-linked epoxy and the epoxy sample filled with 10Â wt% sol-gel-formed silica nanoparticles. As the strain rate increased, the compressive modulus and transition strength of both samples went up distinctly, the strain at break and ultimate strength decreased more or less, while the strain energy at fracture nearly did not change. Adding the sol-gel-formed silica nanoparticles can improve effectively the compressive modulus, transition strength as well as strain energy at fracture of the epoxy polymer owing to their homogeneous dispersion in epoxy matrix.
