Exova, the global testing, calibration and advisory services provider, has been granted authorisation by aircraft manufacturer Airbus to proceed with its specification AITM 1-0003, which governs Dynamic Mechanical Analysis (DMA) testing.

DMA testing is an instrumental technique in which the mechanical deformation of carbon fiber-reinforced composites is analysed, and focuses on measurement of glass transition temperature. The approval comes following a concerted effort by Exova to obtain Airbus approval for this critical test, including recent investments in new DMA equipment.

The Anaheim, California laboratory, run by Mark Kokosinski, also worked closely with the other Airbus-approved Exova laboratories in Bridgwater, UK and Toulouse, France to ensure that test methods and procedures were well-aligned. The Anaheim laboratory previously obtained Airbus’ authorisation for a range of mechanical and analytical tests. The addition of a local approved laboratory for DMA testing will significantly reduce turnaround times for North American customers.

Rocco Moro, Executive VP for Aerospace in the Americas, said: “As composites play an increasingly important role on large commercial aircraft, there is growing demand for specialised testing such as DMA. This new approval makes Exova the first and only third party testing laboratory in North America to receive Airbus approval for DMA testing and reinforces our commitment to provide technically demanding services to the aerospace industry.”

Exova Anaheim’s primary customer for DMA testing is Spirit AeroSystems in Kinston, NC which requires testing of its Section 15 (Center Fuselage) composite components and Main Wing Spars for the Airbus A350XWB commercial airliner.  Exova is also now in a position to perform DMA testing for other Airbus sub-contractors in North America, which require certification to the Airbus specification.
