High Performance Carbon Fiber Thermoplastic Composites in Aerospace Structures

Purpose and goal

The main aim of the PRACTICE project was to build knowledge about fibre-reinforced thermoplastic composites and their possible applications in the Swedish aerospace industry. The work has revolved around a small-scale demonstrator component, a cargo door structure for aircraft consisting of two components; L-profile and "skin", both with curvature. These have been designed, manufactured and evaluated through several steps. Initial tests that formed the basis for, among other things, material database, process simulation for manufacturing, welding etc.

Expected results and effects

The work has included everything from characterization, design and simulation, to manufacturing, joining, testing. But most important of all, the industrial applications of these thermoplastic composites within the Swedish aerospace industry. The project´s results will form the basis for future R&D project, but also the journey to implement thermoplastic composite materials within the Swedish aviation industry. This i.a. through the manufacturing and design methodology developed within the project, which is necessary for the industrialization of these materials.

Planned approach and implementation

Almost all of the project´s deliverables have been met, but where the timetable for most had to be corrected during the course of the project due to external circumstances. Final demonstrator will be carried out after completion of project during Q2 2023.
