Composite materials in wind energy technology

The  reduction  of  fossil  fuel  dependency  is  an  important  goal  for  both  developed  and  developing   countries   of   the   world.   To   achieve   this   goal,   the   renewable   energy   production,  in  particular,  wind  energy  generation,  must  be  drastically  increased.

Carrying out expert evaluations and updating business plans and feasibility studies of investment projects for the production of continuous basalt fiber, staple fiber and basalt composite products.

This  can  be  realized  by  installation  and  expansion  of  many  off-shore  and  on-shore  wind  parks built with large and extra-large wind turbines. Due to the high costs of repair and maintenance  of  extra-large,  off-shore  or  remotely  located  wind  turbines,  the  reliability  of wind turbines, first of all, its most important part, rotor, should be increased to ensure efficient work for 20 and more years.

The durability and high lifetime of wind turbine can  be  ensured,  among  others,  if  the  wind  blade  materials  have  very  high  stiffness,  strength,  fatigue  damage  and  environmental  loading  resistances  as  well  as  low  weight.  For this, the advanced composites should be developed, improved and utilized in wind turbines.

In  this  chapter,  the  application  of  composites  in  wind  energy  technology,  requirements  to  the  composites,  their  properties  and  constituents,  manufacturing  technologies  and  defects are reviewed. Methods of computational modeling of wind blade materials and promising future directions of their development are discussed.
