ASTM D4018 Tensile Carbon Graphite Yarns Rovings Tows Test Equipment

0 0

ASTM D4018 tensile test for carbon graphite yarns roving tows cover the preparation and tensile testing of resin-impregnated and consolidated test specimens made from continuous filament carbon and graphite yarns, rovings, and tows to determine their tensile properties. ASTM D4018 tensile test for carbon graphite yarns roving tows is ideal for the testing of fibers that have been specifically developed for use as reinforcing agents in advanced composite structures. The ASTM D4018 test results of an impregnated and consolidated fiber should be representative of the strength and modulus that are available in the material.

The properties determined by the ASTM D4018 test method are of value in material specifications, qualifications, data base generation, certification, research, and development. The ASTM D4018 tensile test for carbon graphite yarns roving tows also cover the determination of the density and mass per unit length of the yarn, roving, or tow to provide supplementary data for tensile property calculation. ASTM D4018 tensile test for carbon graphite yarns roving tows include a procedure for sizing removal to provide the preferred desized fiber samples for density measurement. This ASTM D4018 procedure may also be used to determine the weight percent sizing. ASTM D4018 tensile test for carbon graphite yarns roving tows include a procedure for determining the weight percent moisture adsorption of carbon or graphite fiber.
