Most of these tests are carried out on glued samples. For this purpose, we have a bath line in which the aluminium is treated prior to gluing. The treatments applied are: phosphoric-sulphuric anodising (PSA) and phosphoric anodising (PAA). In addition, we have a hot plate press that allows the curing process of metal-to-metal bonded joints to be carried out. For certain two-component adhesives, curing is carried out in ovens, using specifically designed tooling as defined by the manufacturers’ specifications.

To perform these tests, we have IR spectrophotometer equipment with Fourier transform, rotational and ball drop viscometers, pycnometers and Shore D hardness testers. To perform the mechanical tests, we have tools specifically designed to study these materials in addition to different universal testing machines.

Annually, we carry out more than 500 tests related to the characterisation of the mechanical properties of metallic materials .

Within the mechanical testing of metallic materials , our quality system includes 26 standardised procedures accredited by ENAC and NADCAP, and approved by Airbus, Bombardier and Embraer. Using these procedures, we perform the following tests on film-type structural adhesive materials: Appearance of the individual components, compression of rigid plastics, non volatile content, volatile content (foaming structural adhesive films), volatile content, single lap shear metal-metal, apparent density of solid samples, density of liquid samples, density of solid or viscous samples, shore d hardness, specific gravity, apparent, of liquid samples, compression modulus test of rigid plastics, floating roller peel, t- peel test, compression stress test of rigid plastics, peel strength at 180° of adhesive bonds, cure time, pot life, tensile strength of butt joints, and viscosity: determination using a single cylinder type rotational viscometer method.
