1.1 This guide establishes the essential and desirable elements of data required for the identification of composite materials in computerized material property databases. A recommended format for entry of these fields into a computerized database is also provided. Examples of the application of this guide are included for filament-wound polymer-matrix composites, laminar polymer-matrix composites, and ceramic-matrix composites. An example for metal-matrix composites is planned for the next revision.

1.2 The recommended format described in this document is suggested for use in recording data in a computerized database, which is different from contractual reporting of actual test results. The latter type of information is described in a materials specification or shown on business transactions, and is subject to agreement between vendor and purchaser.

1.3 This guide defines the information which is considered essential to uniquely describe a composite material. A format is recommended for placing these data in fields suitable for a computerized database. Additional fields which are considered desirable, but not essential, are also defined. The purpose is to facilitate efficient storage and retrieval of the information with a computer and to allow meaningful comparison of data from different sources.
