Wind turbines are the devices used to harness wind energy. The turbine blades are one of the components which directly confront the wind and convert it into mechanical energy. Various material composites are used in the turbine industries to manufacture wind turbine blades but it is hard to select the best material composite along with the choices. In this study, an MCDM technique named Measurement of Alternatives and Ranking according to Compromise Solution (MARCOS) method is applied to select the best material composite among the set of materials for manufacturing of the blades. The weights of the criteria are determined by the Best Worst (BWM) method. Around 9 criteria such as the ultimate tensile strength, stiffness, cost of the materials, panel stability parameter of the material etc. are used to rank the best alternative among the blade materials. The carbon fibre reinforced plastic is seen to be the best material among the other materials composite by applying the MARCOS method.

Lightweight Component

Mit verschiedenen Industriepartnern und dem Fraunhofer AGP wurde ein Fertigungsverfahren zur Herstellung von Stabtragwerken aus faserverstärktem Kunststoff (FVK) entwickelt. Es erlaubt, beliebige Tragwerksstrukturen als ein integrales und besonders leichtes Bauteil direkt aus den Halbzeugen Roving und Matrixharz ressourceneffizient sowie kostengünstig herzustellen. Das Verfahren ist weitgehend automatisierbar. Zu den Produktbeispielen zählen unter anderem Masten, Brückenstrukturen und Rotorblätter von Windkraftanlagen.   Fraunhofer AGP has developed a process for manufacturing fibre-reinforced plastic (FRP) rod frameworks. The semi-finished products roving and resin are used to manufacture almost a random number of spatial structures as an integral and very lightweight component in a resource-efficient way at low cost. Large parts of the process can be automated. Product examples are masts, bridge structures and wind turbine blades.
