In FIX3HYB, so-called draping molds are developed for the three-dimensional shaping, fixation, and stabilization of the hybrid textiles used. Systems such as pins, Velcro fasteners, and snap fasteners are used for fixation. Additional elements are used as needed to secure the interlayers. In addition, the textiles are pre-compacted using 3D shell elements, so that the […]

Development of a quality-assured process chain for the production of functionally integrated and multiaxially reinforced pultrusion profiles made from natural-fiber-reinforced bioplastics.

The “KaskaWi” collaborative project is developing new approaches to keep FRP from end-of-life construction waste in the material cycle for as long as possible. Instead of shredding the components, the goal is to specifically reuse suitable components and semi-finished products in new construction applications based on their remaining properties.

In HOPAR, demonstrators featuring a leading edge made from innovative hightemperature CFRP are being developed to address technical issues through construction and flight testing. This, in turn, minimises the development risk. Figure 1 illustrates the process route, ranging from the definition of the key constraints through to the selection of materials and processes, and finally to the finished demonstrator.

The international security situation is becoming increasingly unstable, and attacks on security and emergency response personnel are steadily on the rise. As a result, the demand for personal protective equipment (PPE) is growing. Many stab-resistant vests and tops available on the market—which come in various designs and protection classes—are often non-breathable, heavy, and, in some cases, severely restrict the wearer’s freedom of movement due to the added protective elements such as plates or multi-layer constructions. Lightweight and hybrid materials, combined with new technologies, offer great potential in this area. Instead of the rigid, preformed protective plates that have traditionally been positioned across the entire surface, bio-inspired overlapping structures made of fiber-reinforced composites can be used.
