Ductility can be quantified by the fracture strain, which is the engineering strain at which a test specimen fractures during a uniaxial tensile test. Another commonly used measure is the reduction of area at fracture.The ductility of steel varies depending on the alloying constituents.his tensile test of a nodular cast iron demonstrates low ductility. In materials science, ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire.
Spacer fabric is a specialized three-dimensional textile that uniquely facilitates air flow, breathability and lightweight shape support.pacer fabric is a specialized three-dimensional textile that uniquely facilitates air flow, breathability and lightweight shape support.

The breather and bleeder layer is usually a non-woven synthetic fiber material that comes in a variety of thicknesses and/or weights. Its purpose is to provide a continuous air path for pulling vacuum on the component. When the bag wrinkles against the hard laminate, it traps air and the breather prevents this from happening.
