According to Cetim, 19 mechanical and physico-chemical tests were assessed. This new audit was carried out on the Cetim site of Nantes, France. Cetim says this was the fourth success in a row, without any non-conformity: a unique result in the world, which enhances the higher reputation of Cetim with the aerospace manufacturers and their subcontractors.
Cetim says this renewed Nadcap accreditation is a major recognition in the aerospace sector, and it is thereby accredited as a mechanical and physico-chemical test laboratory for composites materials. It says the test demand is growing: composite or non-metallic materials are becoming more and more important in aeronautical or aerospace manufacturing. This contributes to weight savings in structures or airframes under the resulting enhancement of energy efficiency as well as polluting emission abatement.
This accreditation complements that already obtained for metallic material testing: now Cetim proposes a complete Nadcap-certified test offer in the aeronautical and aerospace world and improves its positioning and the growth of its activity with its partners, on behalf of the EADS and SAFRAN groups’ companies amongst others.
To address its clients’ requests, Cetim is regrouping its test facilities dedicated to composite or non-metallic materials on its Nantes site.
The Nadcap accreditation is relevant to the following mechanical tests (on non-metallic materials):
· Tensile test at room temperature.
· Tensile test at non-ambient temperature.
· Tensile deformation measurement.
· Compression test at room temperature.
· Compression test at non-ambient temperature.
· Compression deformation measurement.
· Bending shearing on close supports at room temperature.
· Bending test at room temperature.
· Bending test at non-ambient temperature.
The physical tests are relevant to:
· Density/specific gravity.
· Fibre/resin/porosity rate by acid digestion.
· Fibre/resin/porosity rate by calcination.
· Moisture pick-up test.
· Volatile component rate characterisation.
· Surface density of the reinforcements.
· Surface density of the adhesive/prepreg films.
Finally, it says the thermal analyses are focused on the TGA (Thermo-Gravimetric Analysis) and the DSC (Differential Scanning Calorimetry), whereas, the chemical tests will be focused on the Fourrier transform infrared analysis.
Cobra International will showcase a range of composite products at CAMX 2018, including carbon fibre components for the automotive, transportation, marine, water sports and luxury sectors.
Coriolis Composites has been selected by the National Institute for Aviation Research (NIAR) at Wichita State University (WSU), US, to provide a thermoplastics capable Automated Fibre Placement (AFP) system.
UK company Prodrive Composites has developed a process for manufacturing recyclable composite components that can satisfy future end-of-life requirements without any compromise in the performance of the original parts. The company says the P2T (Primary to Tertiary) process not only simplifies recycling, but endows a composite material with the potential to fulfil three or more useful lifetimes.
