Category Scope
27 Nonmetallic Materials
Includes physical, chemical, and mechanical properties of plastics,
elastomers, lubricants, polymers, textiles, adhesives, and ceramic materials.
For composite materials see 24 Composite
Materials.
Definition
Nonmetallic Materials – Materials that do not have the properties of, or do not contain, metal and that are able to combine with hydrogen to form stable compounds, acids, acidic oxides, and anions.
NASA Interest
Exhaustive Interest : Physical, chemical, and mechanical properties; testing, evaluation, and protection of nonmetallic materials (other than conventional building structural materials).
Selective Interest : Research and development on nonmetallic materials that have potential aerospace applications.
Negative Interest : Routine developments of structural nonmetallic materials for use in housing, heavy industry, and earthbound transportation, unless a potential exists for aerospace use.
