Reinforced structural layer and wind turbine blade

Abstract

A reinforced structural layer and a wind turbine blade are provided. The reinforced structural layer includes a plurality of fibers that includes a first fiber, a second fiber, and a third fiber. Any two of the first fiber, the second fiber, and the third fiber are arranged at an angle to each other, and the angle formed between any two fibers is different from the angle between any other two fibers. The plurality of fibers are connected to form a fiber structural layer such that extension directions of the plurality of fibers are oriented in different directions. The reinforced structural layer can form an amorphous reinforcement configuration that effectively resists crack propagation in various directions, thereby effectively countering random crack propagation and providing more comprehensive reinforcement.
