Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide establishes the essential and desirable ele-ments of data requi
3、red for the identification in computerizedmaterial property databases of fibers, fillers, and core materialsused in composite materials. A recommended format for entryof these fields into a computerized database is provided.Examples of the application of this guide are also included.1.2 The recommen
4、ded format described in this guide issuggested for use in recording data in a database, which isdifferent from contractural reporting of actual test results. Thelatter type of information is described in materials specifica-tions shown in business transactions and is subject to agree-ment between ve
5、ndor and purchaser.1.3 The materials covered by this guide include fibers, bothcontinuous and discontinuous, and fillers of various geometrieswhich are used as reinforcements in composite materials, aswell as core materials used in sandwich composites. Cores maybe foam, honeycomb, or naturally occur
6、ring materials such asbalsa wood. These materials are distinguished from bulkmaterials by the importance of their specialized geometricforms to their properties. This difference is reflected in the useof geometry, along with chemistry, as a primary basis forclassification. Identification of composit

The purpose is to facilitate efficientstorage and retrieval of the information with a computer and
18、toallow meaningful comparison of data from different sources.4.2 Comparison of property data from different sources willbe most meaningful if all the essential information defined bythe guidelines is present. Comparison may still be possible ifessential information is omitted, but the value of the c

20、mation should not be considered restrictive.For example, a database designer may find it useful toaggregate several fields, such as the material and chemicalclass fields, into a single field. This may affect search strategiesand other database operations. These considerations are be-yond the scope o
