To provide a bumper beam for automobile which facilitates press molding and is excellent in energy absorption property.SOLUTION: A bumper beam for automobile is composed of a laminate of a carbon fiber-reinforced part composed of two or more layers of carbon fiber-reinforced resin layers (A) and a glass fiber-reinforced part composed of one or more layers of a glass fiber-reinforced resin layer (B), in which each of the layers (A) is composed of a thermoplastic resin and a continuous carbon fiber having orientation in one direction, an orientation angle of at least one layer of the layers (A) is α, an orientation angle of at least another layer of the remaining layers (A) is -α (30°≤α≤90°), the layer (B) is composed of a thermoplastic resin and a discontinuous glass fiber, one surface of two surfaces in the lamination direction of the laminate is formed of a glass fiber-reinforced part, the other surface is formed of other glass fiber-reinforced part, and the orientation angles of all of the layers (A) are ranges of -90° or more and less than -15° or more than 15° and 90° or less.SELECTED DRAWING: Figure 1

    【課題】プレス成形が容易でエネルギー吸収性に優れる自動車用バンパービームの提供。【解決手段】2層以上の炭素繊維強化樹脂層(A)からなる炭素繊維強化部と1層以上のガラス繊維強化樹脂層(B)からなるガラス繊維強化部との積層体からなる自動車用バンパービームであって、層(A)のそれぞれは熱可塑性樹脂と一方向に配向性を有する連続炭素繊維からなり、層(A)のうちの少なくとも1層の配向角がαであり、残りの層(A)のうちの少なくとも1層の配向角が−αであり(30°≦α≦90°)、層(B)は熱可塑性樹脂と不連続ガラス繊維とからなり、積層体の積層方向における2つの表面のうちの一方の表面がガラス繊維強化部によって形成され、他方の表面が別のガラス繊維強化部によって形成され、全ての層(A)の配向角が−90°以上−15°未満または15°を超え90°以下の範囲にある。【選択図】図1
