Huntsman Advanced Materials will highlight its range of solutions for aircraft repairs, focussing on the benefits of Epocast 52 A/B; the first repair system to achieve qualification in accordance with the Commercial Aircraft Composite Repair Committee’s (CACRC) AMS 2980 standard for the structural repair of carbon epoxy airframe components at JEC Europe, Porte de Versaille in Paris, France, next week.
According to Huntsman, the CACRC aims to develop methods and procedures for the repair of composite structures on civil aircraft structures. The organisation involves members from airframe manufacturers, airline users, material manufacturers and aviation authorities. CACRC and the OEMs are responsible for the qualification of repair materials.
Huntsman explains that, following an extensive testing procedure, which was witnessed by Airbus, Boeing and the FAA, the CACRC qualified Epocast 52 A/B as a structural repair material for carbon-epoxy components to be processed by Wet-Lay up (vacuum bagging). Wet-Lay up is often the preferred process for repair due to the simplicity of storage offered and the use of two component resin and dry fibres.
It says that Epocast 52 A/B combines low temperature vacuum bag curing with excellent hot/wet performance (service temperature up to 177C). This system is also qualified to BMS 8-301, Class 1, Grade 2; AIMS 08-01-002-01 and AIMS 08-02-002-01.
Philippe Christou, Head of European Technical Support, Huntsman, said, “A repair has to restore a damaged structure to its original state. It has to be airworthy, durable, damage tolerant and capable of exceeding the life of the aircraft. Repair solutions need to be designed to meet the needs of the OEMs, the airline users and the airline repair shops. As the use of composites in airframe structures increases, several challenges must be addressed. Among these, repair methods and their standardisation are of upmost importance.”
