1. Deformability of unidirectional prepreg materials
Abstract : To reduce cost of structural composites the development of more efficient manufacturing methods is of great interest. Sheet forming of thermoset prepreg, also known as hot drape forming, has been a promising manufacturing method for decades. An automatic tape layer (ATL) can be used to perform the lay-up in an efficient way. READ MORE

2. Towards defect free forming of multi-stacked composite aerospace components using tailored interlayer properties
Abstract : Use of lightweight materials is an important part of reduction of fuel consumption by commercial aircraft. A considerable number of structural aircraft parts are therefore built of thin layers of epoxy pre-impregnated carbon fibres stacked to laminates. READ MORE

3. Forming of stacked unidirectional prepreg materials
Abstract : To reduce cost of structural composites, the development of more efficient manufacturing methods is of great interest. An automatic tape layer (ATL) can be used to perform the layup in an efficient way for flat sheets and the second step is by pressure forming the prepreg stack onto a given mould. READ MORE

4. Automated layup and forming of prepreg laminates
Abstract : Composite materials like carbon fiber-reinforced polymers (CFRPs) present highly appealing material properties, as they can combine high strength with low weight. In aerospace applications, these properties help to realize lightweight designs that can reduce fuel consumption. READ MORE

5. Tooling and processing for efficient and high tolerance prepreg composite manufacturing
Abstract : Composite use is normally motivated in aircraft design by improved weight-specific mechanical properties as compared to metals. However, fatigue and dielectric properties may also be critical for material selection. READ MORE
