Processing and Mechanical Properties of High Temperature/High Performance Composites. Book 3, Section 2: Strength and Fracture Resistance. Part 2.

摘要

The third annual report of the University Research Initiative project at UCSB on High-Temperature, High-Performance Composites consists of sections compiled in a total of six books. The first section in Book 1 is concerned with the properties and structure of bimaterial interfaces and the related problem of coating decohesion and cracking. The second section describes research on the strengths and fracture resistance of brittle matrix composites manufactured with fibers, whiskers and ductile phases. This information is presented in Books 2 and 3. The third section addresses the flow and creep strength of reinforced systems, with emphasis on effects of aspect ratio and the incidence of damage, and is offered in Book 4. The fourth section, Books 5 and 6, describes work on processing of intermetallic and ceramic matrices and composites, as well as numerical modelling of the melt-spinning process. This is Book 3, Section 2 of the series. Contents of this section pertain to: Strength and fracture resistance - Ductile reinforcement; and Matrix toughening. Keywords: Toughness, Ceramic composites, Brittleness, Ductility, Whisker composites, Cracks. (aw)
