The invention provides a long-fiber enhanced thermoplastic composite material vane used for a wind energy generator, which is composed of a long-fiber enhanced thermoplastic composite material, wherein the long fiber is glass fiber, carbon fiber or the composite fiber of glass fiber and carbon fiber; the content of the long fiber in the vane is 32-75wt%, the reservation length of the long fiber is 2.8-25mm and can form a mutually-tangled three-dimensional net structure characteristics, and therefore the product has a higher impact resistance, and especially has low-temperature impact resistance; the preferable size of the vane manufactured by the injection molding technology is 46-2200mm; the vane surface is provided with a primer layer; and the primer layer is sprayed with a UV (ultraviolet) photocuring light shade surface. In the product, the vane is manufactured by the injection molding technology, and the product has the excellent performances of simple production technology, low cost, long service life, low specific gravity, low-temperature warping deformation resistance, stable size, no water and moisture adsorption, high strength, low-temperature impact resistance, scratch resistance, ultraviolet aging resistance, chemical solvent corrosion resistance and the like.

The invention relates to a fiber reinforced ceramic-based composite material antenna cover for a wave band W and a preparation method thereof. The fiber reinforced ceramic-based composite material antenna cover is a product prepared from a quartz fiber perform by pre-sizing with a copying-locating tool, repeated and circular soaking and drying, repeated and circular soaking after rough machining,drying thermal treatment, circular soaking of a silica solution after finish machining, and ceramic thermal treatment molding. The quart fiber enhanced silicon dioxide composite material is taken as the raw material. The antenna cover is applied to a wave band W. The antenna cover has high mechanical, thermal and electric performance and high appearance quality, is 2 to 3mm in thickness, passes awave-transmitting performance test on the wave band W, has a wave-transmitting rate of larger than 60 percent, passes static test examination, meets the application requirement of the wave band W of the antenna cover, and fills the technical blank of the technical field.

The invention belongs to the field of composite materials, relating to a molybdenum fibre reinforced resin concrete material. The molybdenum fibre reinforced resin concrete material comprises adhesive kinetosome and aggregate, wherein the adhesive kinetosome is a resin system formed by mixing composite resin, curing agents, diluents and flexibilizers, and the aggregate is of granite particles or gravel particles. The invention is characterized in that the molybdenum fibre reinforced resin concrete material also comprises molybdenum fibre. The raw materials are in following percentage by weight: 9-20% of the adhesive kinetosome, 77-90% of the aggregate and 0.1-3% of the molybdenum fibre. The molybdenum fibre adopts WEDM to cut and process scrapped molybdenum wires; after being cleaned, the molybdenum wire is cut into the molybdenum fibre with required length; and if the molybdenum fibre the surface of which is smooth is adopted, a corresponding processing method needs to be adopted to process the surface thereof so as to increase the bonding strength between the molybdenum fibre and resin and improve reinforcement effect. The composite material has favourable physical and mechanical properties; compared with no-fibre reinforced resin concrete material, the compression strength of the molybdenum fibre reinforced resin concrete material is improved by 15-30%. The molybdenum fibre reinforced resin concrete material can serve as favourable mechanical basic part material.
