Selective Tape-Laying for Cost-Effective Manufacturing of Optimised Multi-Material Components
The aim of the Stellar project is to develop the manufacturing process for high-speed placement of carbon, glass and polymer fibre reinforced matrices, in selected locations in a composite structure, to provide the optimum reinforcement, weight and cost profile within a part.
The concept of this project is to develop the design methodologies, manufacturing processes, equipment and control systems needed for localised placement of different fibre-reinforced thermoplastic composite tapes onto different substrates, creating locally reinforced components that are fully weight-optimised.
To achieve this, the project will focus on development of the Automated Tape Laying (ATL) process to selectively place reinforced thermoplastic tapes in 3 manufacturing routes:
Selective reinforcement of existing components
Direct additive manufacture of components
Manufacture of selectively reinforced tailored blanks for compression moulding
The manufacturing process developed will have a significant effect on the weight of structures, as for the first time it will allow different reinforcement fibres (polymer, glass, carbon) to be used synergistically in the same thermoplastic polymer matrix, to produce hybrid multi-material structural components with optimised performance and weight.
