National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Composite Inorganic Resilient Seal Materials.

AD462222

Publication Date	1961
Personal Author	Smith, L. L.
Page Count	69
Abstract	The principal objective of this research program is to investigate and develop composite materials suitable for use as static and dynamic seals at temperatures ranging from cryogenic to 1200 F and pressures up to 5000 psi. Materials investigated may be grouped as follows: (1) Fibrous composites with pure metal impregnants. An example is stainless steel fiber skeletons impregnated with silver and/or indium with which promising results have been obtained at temperatures of 1000 F for reciprocating shaft seals and -424 F for static seals. (2) Fibrous composites with other impregnants. Included are metal skeletons filled with teflon, silicone, inorganic rubber, and various ceramic compositions. (3) Non-fibrous composites. These consist of ceramic composites containing talc or glass. Studies are included of resilience, fiber orientation, friction and wear, static seals, reciprocating shaft seals, rotating shaft seals, and radiation effects. (Author)
