Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Assurance Testing Inspection Certification. To conduct this test a rectangular flat strip composite material coupon is symmetrically v-notched. A special fixture is used to hold the coupon and load is applied at a specified rate until failure occurs. The data can be used for research and development purposes concerning interply strength or composite material comparison.

Select from list below: Strain gages can be applied to both sides of the specimen to assure that shear and not twisting ast, and failure must occur by shear.

Factors that influence the shear response and should therefore be reported include the following: The materials are either continuous-fiber or discontinuous-fiber-reinforced composites. The test determines shear strain, shear stress and shear modulus. The composite materials are limited to continuous-fiber or discontinuous-fiber-reinforced composites in the following material forms:.

The composite materials are limited to continuous-fiber or discontinuous-fiber-reinforced composites in the following material forms: Note 1 — This shear test concept was originally developed without reference to fiber direction for use on isotropic materials such as metals or ceramics. The sample preparation, including notching, can be done at your facility or by Touchstone.
