Polysulfone composite material as well as preparation method and application thereof

The invention discloses a polysulfone composite material which comprises the following components in parts by weight: 40-90 parts of polysulfone resin; 0.1 to 10 parts of a polyarylamide liquid crystal polymer; 20 to 40 parts of fiber; 0.1 to 0.2 part of an acid acceptor; and 0-0.3 part of an antioxidant. According to the invention, the aromatic polyamide liquid crystal polymer with a special structure is selected to be compounded and combined with the polysulfone resin in situ, and meanwhile, specific fibers are added, so that the fluidity of the material can be remarkably improved, and meanwhile, the defect that the polysulfone resin is easy to crack due to stress is overcome; the problem that in the prior art, the mechanical property of a material is seriously degraded due to the fact that the compatibility of a common liquid crystal polymer and polysulfone resin is poor is effectively solved, the polysulfone composite material with high flowability, high heat resistance and high toughness is prepared, and
