Intrinsic toughening mechanisms are processes which act ahead of the crack tip to increase the material's toughness. These will tend to be related to the structure and bonding of the base material, as well as microstructural features and additives to it. Examples of mechanisms include • crack deflection by secondary phases, • crack bifurcation due to fine grain structure WebFind many great new & used options and get the best deals for POLYMER TOUGHENING (PLASTICS ENGINEERING) By Charles Arends ... multiphase toughening of plastics; graft rubber concentrates; crazing in intrinsically tough high performance thermoset resins; fracture behaviour of rubber-modified high performance epoxies.
