The invention discloses a heat-insulating and noise-reducing nonwoven composite material for automobile interior trim and a preparation method thereof. The composite material is prepared from certain proportions of PP (polypropylene) fiber, PET (polyester) fiber and hollow PET fiber, the mixed fiber is prepared into a composite felt by a certain acupuncture process, and an appropriate die pressing process is adopted to prepare a composite fiber felt. The composite material disclosed by the invention keeps lower surface density, good bending performance and good dimensional stability, can also meet the functional requirements for heat insulation and sound insulation, and can be used for preparing medium and high-grade automobile interior trim materials.
