Tidal Blades

Together with our customer Tocardo, Solico developed, engineered and delivered a total of 6 sets tidal turbine blades. The blades, varying from 2.5 to 4.5m, are engineered in-house. Holland Composites produced the turbine blades and Solico performed quality management during production. The efforts of all parties involved resulted in a fantastic outcome.

On November 26, 2015 the first tidal energy plant in the Dutch Eastern Scheldt was officially opened

High stiffness to weight ratio

The stiffness to weight ratio of a high modulus carbon fiber construction is typically 5 times higher than steel or aluminium.

Freedom of geometry

Double curved shapes are easily produced in composite materials at almost no extra cost. For production of limited series the relatively low moulding costs are an additional benefit.

Low maintenance

Steel structures typically require periodic maintenance such as conservation and paint systems to prevent corrosion. Composites are not susceptible to corrosion resulting in lower Life-cycle costs.

Fatigue

The fatigue resistance of composites is much better than that of metals. Of course fatigue failure also occurs in GRP and CFRP and has to be analysed in detail.

Lightweight

The specific weight of composites varies between 1.5 and 2.0 compared to 2.7 to 7.8 for aluminium and steel.

High strength

In general, fiber reinforced plastics outperform metals (e.g. steel and aluminium) in strength.
