The invention belongs to the technical field of materials, and particularly relates to a composite material and a preparation method thereof. A designed flame retardant enhanced PBT material is prepared from the following raw materials in percentage by weight: 30 to 50 percent of PBT, 10 to 15 percent of brominated flame retardants, 10 to 15 percent of compound flame retardants, 13 to 40 percent of glass fiber, 2 to 6 percent of toughening agents, 0.2 to 0.8 percent of antioxidants and 0.3 to 0.8 percent of lubricating agents. The 750-DEG C glowing filament in the European Union IEC60695 standard is raised to 850 DEG C extinguishment in 2 seconds by the flame retardant enhanced PBT material provided by the invention; the gradually increased requirements of customers on 750-DEG C glowing filaments can be met; meanwhile, the advantages of high intensity, high toughness, fast shaping capability, high cost performance and the like are realized; the requirements of electronic and electric appliance and home-use el
