1、Designation: D 4029 04Standard Specification forFinished Woven Glass Fabrics1This standard is issued under the fixed designation D 4029; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parenth

2、eses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers finished fabrics woven from“E” electrical glass fiber yarns that are intended as a reinforc-ing material in laminated plastic

3、s for structural use. Thisspecification can also be applied to fabrics made of other glasstypes as agreed upon between the purchaser and the supplier.1.2 This specification specifies the terminology, definitions,general requirements, and physical requirements for finishedwoven glass fabrics This spe

4、cification permits the applicationof sizing materials to the glass fiber yarn during manufacturethat helps facilitate weaving. These organic materials aretypically removed from the greige gabric and replaced with afinish that is compatible with the resin matrix specified in thecontracting documentNO

5、TE 1Sizing materials on glass fiber yarns, in most cases, areremoved by various cleaning procedures as 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 This specificati

6、on shows values in both SI units and ininch-pound units. “SI units” is the technically correct name forthe system of metric units known as the International System ofUnits.“ Inch-pound units” is the technically correct name forthe customary units used in the United States. The values in SIunits are

7、provided as information only; the values stated ininch-pound units are to be regarded as standard.1.4 This specification is one of a series to provide asubstitute for Military Specifications: MIL-Y-1140 Yarn, Cord,Sleeving, Cloth, and Tape-Glass; and MIL-C-9084 Cloth,Glass Finished for Resin Laminat

8、es.1.5 Additional ASTM specifications in this series have beendrafted and appear in current editions of the Annual Book ofASTM Standards. These include greige glass fabrics, glasstapes, glass sleevings, glass cords, glass sewing threads, andfinished laminates made from finished glass fabrics.1.6 Thi

9、s standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

20、ike materials, tire cords,electrical insulation, etc. Each of these materials requiredifferent testing atmospheres. It is the intent of this wide spreadin testing atmosphere to allow testing of glass textiles inrespective laboratories where end product test atmosphererequirements differ. The test at

21、mospheres for respective prod-ucts should be controlled as specified in Practice D 1776. It isthe opinion of Subcommittee D13.18 that the physical proper-ties cited in respective specifications would not be affected bythe range selected.
