Fracture Toughness of Sicp/2124Al Metal Matrix Composite

Interfacial Fracture Toughness Measurement and Improvement for Composite/metal Interfaces

Adhesive bonding is enlarging its application range as a practical method for the joining of dissimilar materials in automotives, aircrafts, microelectronics and medical devices industries replacing conventional joining techniques such as welding, bolting and riveting [1-5]. Especially for joining of fiber-reinforced polymer (FRP) composites to other structural materials such as metal, traditio...

Fracture Toughness of Metal Castings

Marginal fracture toughness of composite resins.

The marginal fracture toughness of several types of composite resins was determined by means of the rattler test. Microparticle-filled resins showed significantly higher marginal fracture toughness than conventional composites. Posterior restorative composites were intermediate between MFRs and conventional composites. Amalgams were inferior to restorative resins. These data correspond with the...

Measurement of the Fracture Toughness of the Metal-Composite Interface in Composite Repair Systems for Steel Pipework

This paper describes the fracture mechanics approach behind the water pressure ‘blow-off test for characterising the failure behaviour of composite repairs on steel tubes. The technique enables the fracture toughness of the metal/composite interface to be determined at the point where failure initiates. Surprisingly the values found for the interfacial fracture toughness are typically an order ...

Fracture toughness of composite and unfilled restorative resins.

Fracture toughness, critical strain energy release rate, and critical stress intensity factor were determined for experimental and commercial restorative resins. A composite resin had lower resistance to crack initiation than an unfilled acrylic resin. The data were consistent with surface failure observed in single-pass wear studies of these resins.
