Inorganic fiber

The tensile strength of materials is dependent on the treatment and form of the material. Thus, the tensile strength of isotropic bulk nylon-6,6 is less than that of anisotropic oriented nylon-6,6 fiber. Inorganics and metals also form fibers and whiskers with varying tensile strengths (Table 14.1). Fibers are generally less crystalline and larger than whiskers. 

Fiber, inorganic Fibers used in RPs, etc. include glass (different types), aluminum silicate, beryllium glass, carbon, ceramic, graphite, and quartz (fused silica).

Centrifugation is often followed by depth filtration. Alternatively, several depth filtration steps can be employed for clarification instead of centrifugation, especially for bench-, pilot-, or smaller commercial-scale applications [133]. Within depth filters, the particles are trapped in the internal matrix of the packed, porous material having a void volume of up to 85%. They are typically composed of cellulose fibers, inorganic filter aids such as diatomaceous earth, inorganic charged resin binders, and synthetic polymers. As the retention mechanism of depth filters is not absolute, some particles will get through, and it is not possible to define a minimum particle size that will be held back. Therefore, an additional membrane...

Seymour, R. B. (ed.), Pioneers in Polymer Science , Kluwer, Boston, 1989. The proceedings of an ACS Symposium that is dedicated to the 12 Nobel Laureate polymer scientists and 11 other scientists who have been largely responsible for the development of polymer science. Chapters are written by Stahl, Mark, Sperling, Fisher, Marvel, Carraher and Pauling, and detail the contributions made by pre 20th century polymer pioneers to the modern scientists in the areas of plastics, fibers, inorganic polymers, elastomers and engineering polymers. 

Figure 15.6 shows the ideal stress-strain curves of inorganic and polymer fibers. Inorganic fibers typically have higher strength and modulus, but they break at lower strain and are more brittle.
