A lightweight and sustainable solution that reduces fuel consumption and CO2 emissions is the manufacture of vehicle parts made of composite materials instead of steel. This also applies to commercial vehicles like trucks, which are strongly used every day. Carbon Truck & Trailer GmbH (CarbonTT) develops and also has the know-how as well as various intellectual property rights to produce and assemble truck chassis from carbon fiber-reinforced composites.
The composite chassis portion can be manufactured continually using pultrusion technology from a Covestro Baydur PUL polyurethane matrix system. This improves productivity compared to standard production.
Covestro will be exhibiting such a composite element in K 2019. Using a Baydur PUL polyurethane (PU) matrix system, it can be generated continually.
CarbonTT developed and optimized the profile design of the composite part to meet mechanical requirements, achieve maximum weight reduction as well as minimize costs. With its Baydur PUL scheme and its knowledge in optimum pultrusion processing, Covestro promotes CarbonTT. Pultrusion runs were carried out effectively to show the advantages of the PU scheme and are being extended.
The pultrusion method is an ongoing method that can be highly automated and is presently in the phase of industrial application to be achieved. This enables highly efficient production of differentiated as well as complicated composite components, particularly when an appropriate polyurethane resin is being used.
Baydur PUL has many superior components and handling characteristics compared to the other resin systems used for pultrusion. The superior mechanical characteristics of PU-matrix components allow clients to create thin profiles as well as useless complicated fiber strengthening where possible. With high reactivity, the viscosity of the system is also very low, which, however, enables the customers to produce very effectively and efficiently at high throughput rates.
