Tensile and Fracture Properties of Silicon Carbide Whisker-Modified Cement-Based Materials

Microstructure and Fracture Toughness of Hot-Pressed Silicon Carbide Reinforced with Silicon Carbide Whisker

The effects of p-Sic whisker addition on the microstructural evolution and fracture toughness (K,c) of hot-pressed SIC were investigated. Most of the whiskers added disappeared during the densification process by transformation into the a-phase. The remaining whiskers acted as nuclei for grain growth, resulting in the formation of large tabular grains around the whiskers. The tabular grains aro...

Silicon Carbide Whisker-mediated Plant Transformation

With the advancement in molecular biology, several metabolic and physiological processes have been elucidated at molecular levels discovering the involvement of different genes. Since the advent of plant transformation 33 years ago, use of plant transformation techniques sparked an interest in fundamental and applied research leading to the development of biological and physical methods of fore...

Tensile Properties of Hydroxyapatite Whisker Reinforced Polyetheretherketone

Polyetheretherketone (PEEK) was reinforced with 0-40 vol% hydroxyapatite (HA) whiskers using a novel powder processing and compression molding technique. A powder mixture was uniaxially pressed into a composite powder compact and compression molded into a flat composite bar using an open-channel die, such that the HA whiskers exhibited a preferred orientation along the length of the bar and ten...

Shock-wave strength properties of boron carbide and silicon carbide

Processing and tensile properties of hydroxyapatite-whisker-reinforced polyetheretherketone.

Polyetheretherketone (PEEK) was reinforced with 0-50 vol% hydroxyapatite (HA) whiskers using a novel powder processing and compression molding technique which enabled uniform mixing at high whisker content. Texture analysis showed that viscous flow during compression molding produced a preferred orientation of whiskers along the specimen tensile axis. Consequently, the elastic modulus or ultima...
