PHYSICAL AND CHEMICAL-PHYSICAL TESTS OF COMPOSITE LAMINATES

PHYSICAL AND CHEMICAL-PHYSICAL TESTS OF COMPOSITE LAMINATES

The chemical-physical tests on the CFRP/GFRP product are used to verify that the finished product satisfies the design characteristics.

The following tests can be used to evaluate the raw materials in the acceptance phase, to verify the aging status, to verify the raw materials in the requalification phase or to verify the optimization of the production processes.
