We are developing a new technology to bond different types of composites together. This hybrid technology bonds thermoplastic composites with thermosets. The aim is to make aircraft and other large structures lighter and more sustainable.
The aviation industry must accelerate its transition to sustainability in order to reduce its climate impact and meet European emissions targets. New, sustainable technologies are needed to produce lighter aircraft.
Objective
The HyWeld project focuses on joining two types of materials: thermoplastic composites and thermosetting composites. The main difference is that a thermoplastic softens when heated and can be moulded into any desired shape. A thermosetting material, on the other hand, retains its shape and structure when heated. Currently, thermosetting materials are predominantly used in the aviation industry.
We are developing various technologies for the application of thermoplastic composites in large structures, including aircraft. Within the HyWeld project, our aim is to use a combination of these two materials, thereby enabling new applications that do not yet exist. With hybrid welding technology, designers can reliably join components made from both materials. In this way, they combine the strong properties of thermoplastics with the well-established and scalable supply chain of thermosets. Our approach is to accelerate the transition to a future-proof aviation industry.
Phasing
We are using an aircraft door surround structure for this purpose. Strict certification requirements are central to every step. The project will be carried out in three phases:
This project is funded bij RVO, Rijksdienst voor Ondernemend Nederland (the Netherlands Enterprise Agency).
The next generation of aircraft will need to reduce their CO₂ emissions in many areas. In this project, we are focusing on improving the leading edge of aircraft wings.
SAM XL develops smart robotic solutions for welding ship panels together. This is currently mainly done manually.
Carrying out maintenance quickly and efficiently is essential in the aviation industry. We develop smart software and robotics solutions for the maintenance, repair and overhaul of existing aircraft components.
The digital knowledge of employees in the manufacturing industry is often limited. This project will focus on speeding up the development, broadening and deepening of that digital knowledge.
Research institutions and companies are collaborating to enable the production of lightweight aircraft. The innovative technologies focus on the machining of thermoplastic composites.
The manufacturing sector is in desperate need of digitally skilled staff. Together with other knowledge institutions, SAM XL is committed to fostering versatile expertise in digitalisation and automation.
SAM XL is advancing new technologies for continuous ultrasonic welding and – together with partners – thermoforming of thermoplastic composites so they can be applied in industrial manufacturing of large, lightweight aircraft structures.
SAM XL is developing future production technology using smart robots. These robots can be deployed flexibly: they adapt their operations quickly, without the need for additional programming. This makes variable production straightforward.
