GRP for renewable energies

Solar plants need substructures that are as durable as possible and whose material is easy to process. In the case of very large installations, the renewal of the substructure is associated with a considerable amount of work and thus high costs. A decision in favor of composites always pays off here.

are complex technical constructions in which e.g. corn silage, liquid manure and household waste are used to create a substrate that is processed into biogas by fermentation. Many building components here are in chemically aggressive and humid environments. GRP is also recommended here.

As in all structures in the vicinity of water, designers place particular emphasis on building materials that are resistant to corrosion, while at the same time offering material properties such as high strength, UV resistance and freedom from maintenance. Composites are therefore the first choice.

The blades of wind turbines can easily have a length of 80 to 100 m. They are hollow on the inside for weight reasons and, since very high forces act on them, would break without additional effective internal reinforcement. Flat profiles made of carbon fibre composites, CFRP, are suitable for this. They are very lightweight, with a high degree of stability.
