External casing components for urban buses and longdistance coaches

For many years, we have been developing casing components for the exterior of buses and railway vehicles here at TC. One advantage of GRP profiles is that we can produce different component lengths based on just one tool. This increases flexibility in design. The components are based on a profile made of glass fibre-reinforced plastic, which we process in our CNC-controlled milling machines to produce
precision-cut parts for e.g. wheel arches, indicators and maintenance covers. We can also install reinforcements or add-on parts at the same time if required.

Repair side walls for urban and overland buses

The side walls of urban and overland buses are put under major strain by the day-to-day demands placed on them: stone chipping, scratches and minor and major accidents quickly cause damage to the thin-walled metal sheets found in older models. What's more, in some cases the effects of weather and chemicals such as de-icing salts and cleaning products can lead to unsightly signs of corrosion, which can damage the image of the bus company among its customers. This makes repairs and touch-ups necessary.

As non-corrosive plating is not always available for older vehicles, TC manufactures side walls made of glass fibre-reinforced plastic that are suitable for all such models and makes, and provide an optimal and durable alternative to older metallic plating.

Mobile platforms

We can create mobile platforms on request. Discuss your mobile platform requirements with us. For mobile platforms we generally use GRP construction profiles manufactured in accordance with EN 13706 / E23. This ensures that the platform has a minimum load-bearing capacity. These GRP construction profiles typically have an isopolyester resin matrix. For structures that are exposed to higher chemical stress, we can also use profiles with a vinyl ester resin matrix. If profiles need to be connected with angle brackets, we generally use V4A stainless steel connectors. We do not use short GRP remnants for such connections because they are not sturdy enough.

Spray and touch protection

We have already designed and built an array of different spray protection systems for indoor and outdoor use at industrial plants on behalf of our customers. These traditionally consist of a load-bearing system made of weather-resistant GRP profiles and transparent, weather-resistant plastic panels. The spray protection system has already been enhanced with e.g. fastener frames for electric distributors, pipe supports, GRP cable bushing systems, GRP doors and ports and special openings for sample extraction. As the GRP spray protection systems for outdoor use are also exposed to high wind loads, we are happy to provide auditable static analysis from an independent structural engineering firm to confirm their stability.

GRP profiles for energy efficiency in the constructions industry

Global climate change and the necessary decline in the dependence on fossil fuels lead directly to better insulation for all types of buildings. The energy footprint of buildings is greatly affected by its windows and doors. Conventional materials such as steel, aluminium, PVC and wood only meet requirements for energy efficiency, durability, robustness, cost-effectiveness and low maintenance to a certain extent. By contrast, pultruded composite profiles can absorb high mechanical loads while also meeting insulation requirements.

0 to 100 km/h in 2.9 seconds – thanks to carbon

Carbon is a composite material and differs significantly from quasi-isotropic materials like steel or aluminium. As with glass fibre-reinforced plastics, the material properties depend on the direction. With a density of approx. 1.6 g/cm³, the material is very light, while maintaining good rigidity and vibration behaviour. If you want to increase the rigidity of a GRP component, it is often sufficient to use a blend of glass and carbon fibres.
