ASTM's composite standards are instrumental in the evaluation and determination of the physical, shear, tensile, flexural, and compressive properties of various forms of composite materials used in structural applications. These composites can be in the form of sandwich core materials, honeycomb core materials, polymer matrix composite materials and their laminates, fiber-reinforced polymer-matrix composite plates and bars, fiber reinforced metal matrix composites, carbon fiber-epoxy prepregs, continuous filament carbon and graphite fiber tows, hoop wound polymer matrix composite cylinders, sandwich beams, flat composite panels, simply supported sandwich composite plates, and fabric-reinforced textile composite materials. These composite standards are also helpful in guiding manufacturers and users of such materials in their proper fabrication and testing for the assurance of their quality.
