ASTM D3518 / D3518MStandard Test Method for In-Plane Shear Response of Polymer Matrix Composite Materials by Tensile Test of a ±45° Laminate
ASTM D3518 is a test method, which measure the shear stress and shear strain properties of polymer matrix composite materials composed of +45 plies and -45° plies. Calculations include shear stress and strain, shear modulus of elasticity and offset shear strength.
Before conducting ASTM D3518, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
