Advanced And Lightweight Composite Outlet Guide Vanes - CACTUS

The project focuses on two main areas: manufacturing methods and material systems. It introduces new reinforcement materials that can improve performance and reduce weight compared to traditional reinforcements. Although these modern materials are commercially available, they are not yet widely used in the aerospace industry. Using these lightweight composite materials can significantly reduce the weight of aircraft and engines, leading to lower CO2 and greenhouse gas emissions. This aligns with Flightpath 2050 Europe’s vision for aviation and other climate goals for 2050.

An innovative solution is the Gapped UD material from Oxeon. A high-performance UD carbon fiber fabric with controlled gaps in the weave for better resin flow in, for example, RTM injection. Another aspect of the project is the introduction of metal parts, such as end-fittings and leading edges, where new adhesive bonding methods will be developed and tested.

The project is divided into several activities, ranging from small-scale tests to the manufacture of guide vanes over the 18 months of the project. The fundamental study of material compaction, permeability, and composite/metal joining will clarify the key parameters for manufacturing advanced guide vanes on a full scale.

The project will demonstrate how new materials and bonding techniques can be used in the next generation of aeroengines and strengthen the collaboration between the project coordinator Oxeon and the project participants GKN Aerospace Sweden and RISE AB, improving the consortium’s and Sweden’s position in the global aerospace industry.
