Abstract

This specification primarily covers glass fabrics woven from 'E' electrical continuous glass fiber rovings that are intended primarily as a reinforcing material in laminated plastics for structural use. The basic designation for glass woven roving fabric is by mass per unit area and is given in grams per square metre. The roving shall be continuous filament fiber, free of any free alkali, such as sodium or potassium metal salts and foreign particles, dirt, and other impurities. For the given woven roving fabrics, the average fabric count, average size-free yarn numbers, filament diameter, average mass per unit area, and fabric length shall conform to the requirements specified. For woven roving fabrics, the roving designations, strand construction, and fabric width shall be agreed upon between the purchaser and the supplier. For the given woven roving fabrics, the weave type shall be plain weave. The woven roving fabric shall be generally uniform in quality and condition, clean, smooth, and free of foreign particles and defects detrimental to fabrication, appearance, or performance. Woven roving fabric shall be furnished in rolls and shall be wound on spiral tubes.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification primarily covers glass fabrics woven from E electrical continuous glass fiber rovings that are intended primarily as a reinforcing material in laminated plastics for structural use.

1.2 This specification specifies the terminology, definitions, general requirements, and physical requirements for woven roving glass fiber fabrics. This specification permits the application of sizing materials to the glass fiber roving during manufacture that helps facilitate weaving. When used as permitted in this specification, such materials are compatible with the resin matrix as specified in the contracting instrument.

Note 1Sizing materials on glass fiber yarns, in most cases, are removed by various cleaning procedures as a first stage in preparing a finished fabric. When these yarn sizing materials are removed during a cleaning procedure, they need not be compatible with the subsequent resin matrix.

1.3 Units The values stated in either SI units or inch-pound units are to be regarded as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

Note 2This specification is one of a series to provide a substitute for the following Military Specifications:
MIL-Y-1140H Yarn, Cord, Sleeving, Cloth, and Tape-Glass
MIL-C-9084C Cloth, Glass Finished for Resin Laminates
MIL-C-19663C Cloth, Glass, Woven Roving for Plastic Laminates
