To provide a fiber-containing resin molded article that can improve impact resistance while improving rigidity or reducing weight.SOLUTION: There is provided a fiber-containing resin molded article, which is a generally plate-shaped member containing vegetable fibers and a thermoplastic resin, and is characterized in that a repeating pattern of continuous convex portions 30 is formed on at least one side 12b. When the fabric weight is the same as that of a molded article without a repeating pattern, the rigidity can be improved compared to the molded article. On the other hand, when the same rigidity as a molded article without a repeating pattern is secured, reduction of the basis weight, that is, weight reduction in comparison with that molded article can be achieved. Due to the presence of countless convex portions, a force applied to the molded article 10 in a thickness direction can be dispersed in a plane direction, and an impact applied to the molded article 10 can be absorbed and cracking caused by the impact can be suppressed.SELECTED DRAWING: Figure 2
【課題】剛性向上あるいは軽量化を図りつつ、耐衝撃性を向上させることが可能な繊維含有樹脂成形体を提供する。【解決手段】植物性繊維と熱可塑性樹脂とを含有する概して板状の部材であり、少なくとも一方側の面12bに、凸部30が連続する繰り返しパターンを形成する。繰り返しパターンのない成形体と同じ目付けとすれば、その成形体に比較して、剛性を向上させることできる。一方、繰り返しパターンのない成形体と同じ剛性を確保する場合には、その成形体に比較して目付けを低減させること、つまり、軽量化することが可能である。また、無数の凸部の存在によって、当該成形体10に加わる板厚方向の力を、面方向に分散させることができ、当該成形体10に加わる衝撃を吸収し、衝撃による割れを抑制することができる。【選択図】図2
