1、Designation: D4389/D4389M 16Standard Specification forFinished Glass Fabrics Woven From Rovings1This standard is issued under the fixed designation D4389/D4389M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last revi
2、sion. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification primarily covers glass fabrics wovenfrom “E” electrical continuous glass fiber rovings that areintended prim
3、arily as a reinforcing material in laminatedplastics for structural use.1.2 This specification specifies the terminology, definitions,general requirements, and physical requirements for wovenroving glass fiber fabrics. This specification permits the appli-cation of sizing materials to the glass fibe
4、r roving duringmanufacture that helps facilitate weaving. When used aspermitted in this specification, such materials are compatiblewith the resin matrix as specified in the contracting instrument.NOTE 1Sizing materials on glass fiber yarns, in most cases, areremoved by various cleaning procedures a
5、s a first stage in preparing afinished fabric. When these yarn sizing materials are removed during acleaning procedure, they need not be compatible with the subsequent resinmatrix.1.3 UnitsThe values stated in either SI units or inch-pound units are to be regarded as standard. The values stated inea
6、ch system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in nonconformancewith the standard.NOTE 2This specification is one of a series to provide a substitute forthe following Military Specifications:MIL-
