The invention provides a low-odor glass fiber-reinforced polycarbonate composite material which is prepared from the following raw materials in parts by weight: 60-90 parts of polycarbonate, 5-40 parts of a short glass fiber reinforcement, 3-10 parts of an interfacial compatibilizer, 1-5 parts of a first deodorant, 1-5 parts of a second deodorant and 0.1-1 part of an antioxidant. The invention also provides a preparation method of the low-odor glass fiber-reinforced polycarbonate composite material. The preparation method provided by the invention uses glass fibers for modifying during material filling, and can effectively control odor of the composite material with the aid of the interfacial compatibilizer and the deodorants while further improving mechanical properties of the material; and the composite material especially has outstanding performance in a high-content glass fiber system, and has an odor level not much different from that in a low glass fiber content. 本发明提供了种低气味的玻璃纤维增强聚碳酸酯复合材料，由以下重量份的原料制备而成：
