Abstract:
1. An FRP panel for an automobile comprising at least two FRP layers separated from each other with a first of the FRP layers on a first surface side and a second of the FRP layers on a second surface side on an opposite side of the first surface, wherein i) the first of the FRP layers and the second of the FRP layers are formed either (1) as an FRP solid plate formed integrally with the first of the FRP layers and the second of the FRP layers or (2) as a structure which has a space between the first of the FRP layers and the second of the FRP layers and in which the space is left intact or a core material is disposed in the space, ii) either of the first and second FRP layers is formed as a lower-strength FRP layer, and the lower-strength FRP layer forms a crushable structure that absorbs impacts to a pedestrian during a collision, wherein differences in strength are provided by one or two or more differences selected from the group consisting of a difference in amount of reinforcing fibers, a difference in property of reinforcing fibers and a difference in orientation of reinforcing fibers, and iii) each of the FRP layers is formed integrally as an FRP solid plate and said difference in strength is provided by providing a high breaking elongation layer on the lower strength FRP layer.
