Re-design of commercial aircraft interior components incorporating sustainable FR308 composites

SHD recently supplied established aircraft interior company Percival Aviation with FR308 – a novel bio-based, fully FST compliant resin system for use in aircraft and rail interior applications. The highly sustainable product, initially derived from a waste product of cane sugar production, ultimately finding applications on Boeing and Airbus aircraft.

In an initial program, the end customer needed to extend the storage capability of overhead bins on their Boeing 757 aircraft. Percival Aviation created a solution that allows passengers on the aircraft to stow their luggage lengthways, instead of width-ways, and so enables more passengers to put their bag in an overhead bin.

The resin was tested for full conformance with aircraft interiors standards and was used in the overhead bin doors to replace a traditional fossil fuel derived phenolic prepreg. Utilising the resin increased the durability of the new OHB Doors. The improved surface finish of FR308 reduced the need for filling and re-work, reducing both the weight of the part and the cost of manufacture.

This was the first time FR308 had been used in a commercial passenger aircraft, marking an important milestone in the development of the material. Subsequently, through their EASA-certified design (Part 21J), production (Part 21G) and EASA Part 145 capabilities, Percival Aviation has used FR308 for the manufacture of a wash basin door of an Airbus A320 aircraft.

FR308 reinforced with 300gsm glass fibre is environmentally, and health and safety friendly in comparison to alternative products. There are no hazardous chemicals, the product is formaldehyde and phenol free, and no organic solvents are used in the manufacturing process. As FR308 is bio-based and sustainably sourced, it can significantly reduce the carbon footprint of the aircraft versus phenolic prepregs.

Customer Testimonial

Ian Leece, Operations Manager at Percival Aviation commented “the team at SHD were easy to work with and provided a suitable solution at a reasonable price. As the FR308 is a renewable bio resin system, it helps keep in line with our company environmental policy. Overall we were very impressed with the product and will return for future projects.”

We are exhibiting on stand 6F111 at Aircraft Interiors Expo, Hamburg, between 6-8 June 2023. During the show, we will be underlining the importance of the aerospace market and how we have grown to be a truly global supplier, serving customers across all major sectors, including aircraft interiors.

We will, in particular, be sharing our developments in the vital area of increased sustainability and material circularity with a focus on localised supply chains. On the stand, you will find a range of components made from SHD materials that include both increased levels of bio-sourced content, but also demonstrate how we are focused on lowering CO2 footprint and developing “end of life” solutions. On display are fully bio-based PFA parts including (FR308) commercial aircraft interior components as well as 100% bio-sourced panels and some novel product developments using recycled and aligned carbon fibres.
