PCT No. PCT/SE87/00036 Sec. 371 Date Sep. 21, 1987 Sec. 102(e) Date Sep. 21, 1987 PCT Filed Jan. 28, 1987 PCT Pub. No. WO87/04400 PCT Pub. Date Jul. 30, 1987.A turbine blade produced from reinforced plastic material having a plurality of reinforcement sections (4, 6), arranged so that the direction of the reinforcement, and/or the structure, and/or the material in one section (4) differs from the corresponding reinforcement in another section, (5, 6), but that the reinforcement material in one section extends mainly in the same direction. The turbine blade also is so designed, that the deformations caused by loads and stresses optimize its pitch at increasing load.
