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...

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.

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...

A Novel Polymer - Derived - nanoCeramic for Ultrahigh Temperature MEMS Micro

Polymer–derived ceramics (PDCs) constituted from silicon, carbon, nitrogen and oxygen embody not only remarkable resistance to creep, thermal shock and oxidation at very high temperatures, but also functional properties such as semiconductivity which extends up to 1350C. In this report we describe the extraordinary sensitivity of the electrical resistance of the PDCs to hydrogen, at temperature...

Fracture toughness of graphene.

Perfect graphene is believed to be the strongest material. However, the useful strength of large-area graphene with engineering relevance is usually determined by its fracture toughness, rather than the intrinsic strength that governs a uniform breaking of atomic bonds in perfect graphene. To date, the fracture toughness of graphene has not been measured. Here we report an in situ tensile testi...
