PROBLEM TO BE SOLVED: To provide a vehicle body reinforcement structure capable of improving ride comfort of an occupant, by making both compatible in weight reduction in vehicle body weight and the vibration damping function, with a simple constitution.SOLUTION: A vehicle body reinforcement structure is reinforced via fiber-reinforced resin band plate materials 21-27 incorporated with a plurality of carbon fibers F, and the plurality of carbon fibers F are arranged so as to extend in the length direction of the band plate materials 21-27 in a base material M, and both end parts 21a-27a and 21b-27b of the band plate materials 21-27 are connected to a pair of connection parts separated in the vehicle width direction of a vehicle body, and are constituted so that the torsional moment acts on the band plate materials 21-27 when the vehicle body is deformed, and two band plate materials 21-24, 26 and 27 are provided so as to become bilateral symmetry to the vehicle body center line, and the connection parts of the band plate materials 21-24, 26 and 27 are provided so as to separate in the vehicle body longitudinal direction.SELECTED DRAWING: Figure 2
【課題】簡単な構成で、車体重量の軽量化と振動減衰機能とを両立させることができ、乗員の乗り心地を向上させることができる車体補強構造を提供する。【解決手段】複数の炭素繊維Fが組み込まれた繊維強化樹脂製の帯板材21〜27を介して補強された車体補強構造において、母材M内で複数の炭素繊維Fが帯板材21〜27の長さ方向に延びるように配列され、帯板材21〜27の両端部21a〜27a,21b〜27bが車体の車幅方向に離隔した1対の連結部に連結され、車体変形時、帯板材21〜27に捩りモーメントが作用するように構成し、車体中心線に対して左右対称となるように2本の帯板材21〜24,26,27を設けると共に帯板材21〜24,26,27の連結部が車体前後方向に離隔するように設けられている。【選択図】 図2
