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...
1.1 This test method is an index test used to measure the force required to continue or propagate a tear in woven or nonwoven geotextiles by the trapezoid method. While useful for quality control and acceptance testing, the trapezoid tear test does not provide all the information needed for...
5.1 It is well known that the prepreg impregnation level affects handling characteristics, tack and drape, and final part quality. Resin impregnation level is the dominant factor in the ability of removing air and volatiles from the layup during processing. Partially impregnated prepreg...
5.1 The grab method is applicable whenever it is desired to determine the "effective strength" of the fabric in use, that is, the strength of the material in a specific width, together with the additional strength contributed by adjacent material. There is no simple relationship between grab...
4.1 PFAS are widely used in commercial and industrial applications worldwide (see Fig. 1). PFAS are of concern due to their documented persistence and their studied impacts on human health and the environmental. While there is no comprehensive source of information on the many individual PFAS...
5.1 This practice provides supplemental instructions for the use of Test Method D6484/D6484M to determine unnotched compressive strength data for material specifications, research and development, material design allowables, and quality assurance. Factors that influence compressive strengths...
1.1 This specification covers flexible sheet made from ethylene propylene diene terpolymer (EPDM) geomembrane intended for use in geotechnical and geoenvironmental applications. The tests and property limits used to characterize the sheet are values to ensure minimum quality for the intended...
5.1 This test practice is designed to produce tensile property data for material specifications, research and development, quality assurance, and structural design and analysis. Factors that influence the tensile response and should therefore be reported include the following: materials...
1.1 This specification covers bridge bearings that consist of a spherical rotational element, where a stainless steel convex surface slides against a concave carbon steel plate covered with woven or sheet polytetrafluoroethyl
5.1 Overlap splices are used in field applications of FRP composites when site conditions prohibit continuous access to a structural element or when the specified length of the FRP composite is such that saturation and placement of the entire length would be cumbersome. This method can be used as a...
