| Zusammenfassung: | To firmly bond a surface treatment layer of a coating film and the like in a state without being peeled off.SOLUTION: A plastic laminate consists of a plate 2 which is made of a plate-shaped fiber-reinforced plastic formed by embedding reinforcing fibers in a thermoplastic resin, and a core 3 which is made of a trapezoidal corrugated fiber-reinforced plastic formed by embedding reinforcing fibers in a thermoplastic resin, and is heat welded to the plate 2. A part or the entire surface of the plate is provided with a smooth surface 2a and an uneven surface 2b having a greater unevenness than the smooth surface 2a, and the smooth surface 2a and the uneven surface 2b are alternately arranged in stripes.SELECTED DRAWING: Figure 1
【課題】塗膜等の表面処理層を剥離しない状態で強固に付着する。【解決手段】プラスチック積層体は、補強繊維を熱可塑性樹脂に埋設してなる板状の繊維強化プラスチックからなる板材２と、板材２に熱溶着してなる補強繊維を熱可塑性樹脂に埋設してなる台形波状の繊維強化プラスチックからなる中芯３とからなり、板材表面の一部ないし全面に、平滑面２ａと、平滑面２ａよりも凹凸の大きい凹凸面２ｂとを設けており、さらに平滑面２ａと凹凸面２ｂとを交互に縞状に配置して設けている。【選択図】図１ |
