Organic/inorganic fibers

The fabricator has a variety of alternatives to choose from regarding the kind, form, amount of reinforcement to use, and the process vs. requirements (Table 8-28). With the many different types and forms (organics, inorganics, fibers, flakes, and more) available, practically any performance requirement can be met and molded into any shape. Possible shapes range from very small to extremely large, and from simple to extremely complex.

Although the pyrolysis of organic materials (organic hollow fibers) is used in the commercialization of a new family of inorganic membranes (Fleming 1988) there are only a few descriptions in the open literature. Koresh and Soffer (1980, 1986, 1987) have published a series of articles on this subject. There is also a paper by Bird and Trimm (1983) which is based on a previously described preparation procedure of Trimm and Cooper (1970, 1973). 

Ultimate Tensile Strength of Representative Organic, Inorganic, and Metallic Fibers... 

The focus here on self-organizing polymers, electrical and optical properties, and biosynthesis is not even close to comprehensive in the enumeration of avenues and opportunities in new polymeric materials. Degradable plastics that do not remain in our environment forever [24] and polymer precursors to ceramics [19] and inorganic fibers are two of many more areas in which new polymeric materials will provide new challenges to engineers in production and processing. 

The need for high-temperature-resistance fibers has arisen from demands of a number of industrial applications, as well as applications in aerospace programs. In many of these applications, the usual characteristics of organic-based fibers are desired, but the high temperature resistance of inorganic fibers is required. Thus, the fibers are expected to retain their structural integrity at temperatures of 300°C and above for considerable periods of time, but otherwise...

There have been some attempts to address this issue. However, the size of the inorganic fibers or spiral wound unit is still quite larger than that of the organic counterparts. To be... 

However, when such insulation mats are exposed to moisture, the bonding strength is reduced, which can affect the quality of the insulation material. To prevent this problem, on the one hand, a hydrophobic agent is added to make the mineral wool more water repellent, and on the other hand silane is included in the binder mixture to enhance the bond between the inorganic fibers and the organic binder. 

Worldwide production of fibers was c t. 45 10 t/a in 1993, of which ca. 20% was inorganic fibers. Whereas at the turn of the twentieth century the fibers utilized were almost exclusively natural fibers (organic fibers cotton, sheep s wool and silk inorganic fibers asbestos), by 1993 the proportion of synthetic fibers had grown to ca. 50%. This trend appears to parallel the increasing world population and the consumer behavior coupled therewith. 

In the following sections the fibers are discussed organized according to application field, the order approximating to the order of their industrial importance. A survey of several inorganic fibers together with their most important application fields is given in Table 5.2-1.
