Abstract
Description
本発明によるワークピースは一般に熱可塑性材料またはある種の小さなグループの熱硬化性プラスチックから製造される。プラスチックまたはプラスチック繊維あるいはプラスチックでコーティングされた他の繊維からなる織編物も材料に含まれる。本発明のワークピースの特徴的設計は、その表面を相手方の表面に融着させ、表面近くで幾つかのポリマー層を各々の方向に整列させることができることである。主な特徴はワークピースの少なくとも表面が加熱により分解ではなく軟化することである。同様に相手方の表面も加熱により軟化しなければならない。ワークピースとこれに融着するべき相手方材料は互いに混和可能(miscible)なポリマーでなければならず、相互に重なり合う溶融温度範囲を持つものでなければならない。
吸収色素をテープ状またはフィルム状などの固形状にしてワークピース表面に配置することも可能であるが、これを液状にして適用することによって格別の有用性が発揮される。この適用方法は本発明の一部を構成するものではないが、多数の適用方法のいずれを採用するかによって付与される特性が異なるから、結果として得られるワークピースは、いかなる意味においても、幾つかの適用方法のみが記述されていることによって限定されるものではない。たとえば、液体投与(liquid dispensing)またはインクジェット印刷は各々異なる柔軟性、コスト効率および均一性を与え、色素を様々な表面、形状、ワークピースの種類、意図する用途およびこれらの組合せに対する適用を可能にする。
図3は一連の透過率グラフであり、曲線70はワークピース10のサンプルの頂面に置いた相手方材料12のサンプルを光が通るときの透過率を示す。両サンプルはポリカーボネートで作製した。次に、1グラム/リットルの吸収色素を含む溶液をワークピース10に塗布してその上に溶接領域を形成した。曲線50は吸収色素を含むワークピース10の頂面に置いた相手方材料12を光が通るときの透過率を示す。
再び図3を参照して、曲線60はパネルが互いに係着(clamp)されておらずしたがって溶接部を持たない場合のレーザ照射後に両パネルを光が通るときの透過率を示す。曲線70は溶接領域が外側を向いていて(facing out)であって溶接されていない場合のレーザ照射後に両パネルを光が通るときの透過率を示す。曲線80は両パネルが適切に向き合って係着され良好に溶接された場合のレーザ照射後に両パネルを光が通るときの透過率を示す。
