Aerogenerator blade composite material

Abstract

The invention discloses a composite material for wind turbine blades, which is composed of a fiber part, a resin part and a metal part. It is composed of amide resin, antioxidant, anti-aging agent and corrosion inhibitor, and each component includes, in parts by weight: 15-22 parts of polyamide resin, 4-9 parts of antioxidant, 2-6 parts of anti-aging agent and 1 part of corrosion inhibitor -5 parts; the components of the metal part by weight include: 3-8 parts of Cu, 2-6 parts of Al, and 1-4 parts of Ti. During preparation, the fiber part and the metal part are dissolved in the resin part in turn. The fiber part in the present invention can give full play to the high-strength and high-model properties of the fiber in its length direction, so as to ensure the overall mechanical performance of the wind turbine blade. The metal part can ensure the corrosion resistance, excellent ductility and strength of the material. The manufactured leaves are non-toxic and harmless to the production environment and can also be recycled.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a composite material for wind power generator blades. Background technique [0002] Wind is one of the energy sources without pollution. And it is inexhaustible and inexhaustible. Wind energy as a clean Renewable Energy , has received more and more attention from all over the world. For coastal islands, grasslands, pastoral areas, mountainous and plateau areas that lack water, fuel, and inconvenient transportation, the use of wind power generation according to local conditions is very suitable and promising. Among the utilization forms of wind energy, wind power generation technology is the most mature and has the most prospect of commercial development. Large-scale use of wind power generation is also one of the effective measures to reduce harmful gas emissions. [0003] Blades are the most basic and critical components of wind turbines. Harsh environment an...

Problems solved by technology

However, there are some shortcomings in the process of producing blades. For example, unsaturated polyester resin is used as the matrix resin, and harmful substances such as styrene overflow during the production process; the curing system using epoxy resin as the matrix resin is mostly organic amines. and other harmful substances

The presence of these substances will cause harm to the environment and operators

At the same time, materials such as polyester resin, vinyl resin, and epoxy resin are all thermosetting materials, and all have the disadvantage of being non-recyclable.
