Description

しかし、車両の、目に見える領域での使用は、繊維強化熱可塑性プラスチック製コンポーネントにとって問題がある。繊維材料に起因して、表面の構造（テキスチャー）が平坦でない状態になり、コンポーネントに課される要求品質を満たすことができないからである。 However, the use of vehicles in the visible area is problematic for fiber reinforced thermoplastic components. This is because the surface structure (texture) becomes uneven due to the fiber material, and the required quality imposed on the component cannot be satisfied.

例を挙げると、Ｍ．Ｂｌｉｎｚｌｅｒは、「ＯｂｅｒｆｌａｅｃｈｅｎｔｅｘｔｕｒｅｎｂｅｉｇｅｗｅｂｅｖｅｒｓｔａｅｒｋｔｅｎＴｈｅｒｍｏｐｌａｓｔｅｎ」[織物強化熱可塑性プラスチックの表面テクスチャ］、Ｋｕｎｓｔｓｔｏｆｆｅ１１／１９９９、第１２８～１３０頁で、熱可塑性プラスチックに織物で強化を施すと表面にはっきりと見えるテクスチャ（織り地）を生じさせること、これは塗装によって高い光沢を示すのであるが、しかし同時に、表面上で不均一性がなお目に見えることを開示している。 For example, M. Blinsler, "Oberflaechentexturen bei gewebeberstärkten Thermoplasten" [Texture Reinforced Thermoplastic Surface Texture ], Kunststoffe 11/1999, pp. 128-130, on the surface of thermoplastics that are clearly reinforced with textiles. Producing a (woven fabric) , which exhibits a high luster by painting, but at the same time discloses that non-uniformity is still visible on the surface .

また、繊維強化熱可塑性プラスチックの表面は通常では、繊維材料と熱可塑性材料の不均一な分布に起因して、繊維の存在を透写する。さらに、冷却時には、熱可塑性材料の収縮は繊維材料よりも大きく、そのため、更なる表面欠陥をも生じてしまう。 Also, the surface of the fiber reinforced thermoplastic usually shows through the presence of the fiber due to the non-uniform distribution of the fiber material and the thermoplastic material. Moreover, upon cooling, the shrinkage of the thermoplastic material is greater than that of the fibrous material, which also results in further surface defects.

Examples of this treatment are increasing the proportion of thermoplastics in the outer layer of the member by reducing the content of the fibrous material, applying the outer layer without affecting the inner region of the thermoplastic member , additional It is mentioned to increase the layer thickness of the paint system by applying a filler layer or an increased amount of top coat, or to apply a dry coating film.
