Exova gains Airbus approval for composites testing

Global aerospace testing group Exova has become the only independent provider in the UK to achieve Airbus approval for a key composite test.

Exova’s Bridgwater lab is now Airbus approved to perform Tg (glass transition temperature testing) using DMA (Dynamic Mechanical Analysis).

As the only independent lab to gain the approval from Airbus, Exova Bridgwater is now able to perform tests on composite parts for all manufacturers within the Airbus supply chain.

Tg testing is used for production quality assurance checks as part of the manufacturing process of composite materials. DMA is a method of determining the glass transition temperature of the resin – the temperature at which polymer bonds begin to move against each other – within a composite material.

This test dictates the temperature at which the mechanical properties of the composite radically change – a key design requirement.

Mark Eldridge, general manager at Exova Bridgwater, said: “This is another key step in developing our capabilities to directly meet customers’ needs, and reflects our goal of offering unrivalled service and composites capability to the whole of the aerospace supply chain.”

Exova Bridgwater has been working closely with Airbus in Filton, Gloucestershire, in order to gain group approval to perform Tg testing as part of aerospace production release checks on critical components , known as Category 1.

Exova’s Aerospace division includes a network of specialist laboratories with facilities in the US, Sweden, Mexico, France and the Czech Republic.
