- Lightweighting Excellence Programme (LX)
- Creation of 238 new jobs
- Total project value of £7.15M
Three UK-based automotive OEMs, namely Bentley Motors Limited, Emerald Automotive LLC and Nissan Motor Manufacturing (UK) Ltd, are working closely with the Lightweighting Excellence Programme (LX)* in order to achieve vehicle weight reduction. The LX consortium is seeking to enhance capability within the UK automotive supply chain to manufacture composite components in medium to high volumes by connecting the key functions of material supply, design and manufacturing.
Total project value of £7.15M
A total project value of £7.15M of joint funding will support the creation of 238 new jobs and safeguard 144 existing jobs between 2015 and 2021. Many UK-based automotive OEMs have expressed interest to source a higher percentage of their composite components from within the UK.
The three OEMs are working on the following ‘Use Cases’:
Bentley Motors – door inner structure
Bentley has offered as a use-case the challenge of replacing a structural door-inner sub-assembly, currently made of numerous metallic parts, with a simplified carbon composite assembly. The door-inner assembly anchors the door’s anti-intrusion beams and mountings for numerous components such as electric window motors, window frame guides and exterior skin connection. Using composite materials, the LX consortium aims to produce a lightweight concept that reduces the number of parts used, while retaining strength, stiffness and crash integrity. This weight reduction could enable increased functionality that is sometimes prohibitive due to the weight of the existing metallic structures.
Emerald Automotive – exterior body panels
Emerald Automotive is developing a lightweight commercial vehicle that could utilise thermoplastic exterior body panels in the future. They are expected to achieve a high quality Class A surface finish that is lightweight, durable and dent resistant. The project outcome will see the LX consortium members working together in a robust supply chain to create a UK-based production facility that uses automated technology and thermoplastic composite moulding know-how to ensure an uninterrupted supply of Class A body panels to help Emerald Automotive meet demand for what will become a popular global vehicle. When the LX consortium has proven rate, process, quality and price, component production numbers are anticipated to be in low to medium volumes.
Nissan – structural component
Nissan believes that significant lightening of the weight of a passenger vehicle by replacing an existing metallic body structure with lightweight carbon composite is a future requirement. One of the most difficult candidate parts for manufacturing in carbon composites could be a structural floor component which Nissan is offering the LX programme for development. The first run of prototypes will be produced in early 2016 as proof of concept, showing high volume manufacturing methodology and processes ready for future full-scale production. The key challenges for the LX partners to overcome are producing a floor that is significantly lighter than the existing metallic part, at a price that is comparable with the existing metallic component it replaces, while maintaining consistent high quality, structural performance and just-in-time delivery to the production line.
