Problems solved by technology
[0004] At present, the normal modulus of blade shell reinforcement materials commonly used in the industry cannot meet the tensile properties required for the design of super-large offshore blades. Increasing the layup and increasing the thickness of FRP to increase the strength of the blade will cause the blade to be overweight. risk of overload

Abstract
The invention discloses a high-modulus high-gram-weight glass fiber fabric TLX1350, which comprises a warp layer, a first diagonal weft layer, a liner weft layer, a second diagonal weft layer and polyester yarns in sequence from top to bottom. The polyester yarns are used for binding of the warp layer, the first diagonal weft layer, the liner weft layer and the second diagonal weft layer. Comparedwith an existing conventional fabric, the high-modulus high-gram-weight glass fiber fabric TLX1350 has advantages that the tensile modulus is increased to 35-45GPa and increased by 25-35%, the tensile strength is improved to 900-1000MPa and increased by 30-40%, and the gram weight in unit area is increased from 1215g / m<2> to 1350g / m<2> and increased by 11%.
Description
technical field [0001] The invention relates to the field of glass fiber products, in particular to a high-modulus and heavy-weight glass fiber fabric for reinforcing wind power blades and a preparation method thereof. Background technique [0002] As a kind of clean and renewable energy, wind energy is close to the bottleneck in the development of land-based wind resources, and people turn their attention to the vast sea area. In the past two years, with the continuous launch of offshore wind turbines by various mainstream machine manufacturers and the increasing number of offshore wind power projects, offshore wind power has become the general trend of wind power development. [0003] Although my country has made many achievements in the development of offshore wind power, there are still many problems and shortcomings in general. As far as blades are the most important large parts of wind turbines, the development of offshore wind power requires the manufacture of suppor...
