The invention discloses a polycarbonate composition. The polycarbonate composition is prepared from, by weight, 50-90 parts of polycarbonate, 5-50 parts of fibrous filler and 0-10 parts of other adjuvants, wherein the sum of the weight parts of the components is 100 parts. The fibrous filler comprises a component I, a component II and a component III, wherein the component I is composed of fibrous filler bodies with the length of 50-100 micrometers and accounts for 3-15 wt% of the fibrous filler, the component II is composed of fibrous filler bodies with the length of 200-400 micrometers and accounts for 25-60 wt% of the fibrous filler, and the component III is composed of fibrous filler bodies with the length of 500-700 micrometers and accounts for 8-30 wt% of the fibrous filler. According to selection, the length and content distribution of the fibrous filler are adjusted in the formula of the polycarbonate composition, the fibrous filler can be distributed in the polycarbonate composition in a trimodal mode, while rigidity of the obtained polycarbonate composition is enhanced, the polycarbonate composition has excellent toughness, rigidity and toughness can be balanced, and applicability and practicality of the composition are improved.
