Engineers from the ACG Applied Technology Group and Duqueine Composites have collaborated in the construction of a large composite jet engine test bench.
Manufactured for their customer, Techspace Aero (a subsidiary of SNECMA Group), Duqueine designed the substantial composite structure and worked closely with ACG in defining a novel manufacturing process to achieve it.
Dependant on their required ultimate service temperatures, the components have been moulded on aluminium tooling in combinations of ACG’s VTM260, VTM240, LTM310 series and ZPREG materials. Properties common to all these products are their ability to cure at 65°C (149°F) initially and produce large “out-of-autoclave” structures, with low void contents and excellent surface finishes. The products’ room temperature outlives range up to 30 days and offer maximum dry service temperatures as high as 180°C (356°F).
ACG manufactured six different composite material formats for the project and provided on-site engineering support during the most testing period of the build.
