摘要： Provided are a method for preparing a unidirectionally aligned discontinuous fiber reinforcement composite material, a unidirectionally aligned discontinuous fiber reinforcement composite material, and a sandwich structure. The method for preparing a unidirectionally aligned discontinuous fiber reinforcement composite material comprises discontinuously aligning short fibers on a polymer substrate in one direction by using an air-laid method.
