A number of works on modifying epoxy properties with polysulfone thermoplastic additives provide data that additives in amounts up to 20% by volume do not change the yield strength, elastic modulus and ultimate deformation. Which is natural, since the mechanical properties of the polymers are similar, but the same works say that in this case the fracture toughness K1c and fracture energy G1c increase. Could this be possible?
