Fracture Property and Fracture Mechanism of Polymer Blends

Improving the fracture toughness and the cyclic-fatigue resistance of epoxy-polymer blends

Relatively tough epoxy-blend polymers are now commercially available for use as adhesives and as the matrices for fibre composites. Nevertheless, another failure property which may be of equal, or even of greater, importance in some applications is the resistance of the epoxy polymer to cyclic-fatigue loading. However, the cyclic-fatigue behaviour of epoxy polymers has not been studied in great...

Fracture Failure Mechanism

The present study investigates the failure mechanisms of industrial fiber materials 13 a custom designed fiber cutting performance test bench. The fracture morpholog 14 fibers are examined by scanning electron microscopy. The analysis reveals that fiber cutting can be 15 distinguished according to four distinct stages of fiber failure represented by shearing, cutting, 16 brittle fracture, and t...

Fracture Toughness of Blends of Nylon 6 with Maleated Elastomers

Fracture of Ceramic-Polymer Composite Biomaterials

Fracture toughness, strength, and elastic modulus of poly(methyl methacrylate) (PMMA)and poly(buty1 methacrylate) (PBMA)-impregnated alumina ceramics were measured as a function of polymer volume fraction, mean polymer particle size, and interfacial bonding between the polymer and ceramic. Fracture toughness was found to increase with increasing polymer volume fraction and decreasing polymer pa...
