Abstract
Description
図1は、本実施の形態に係る溝付き樹脂成形品10(単に「樹脂成形品」ともいう)の断面を模式的に示した図である。溝付き樹脂成形品10は、無機充填剤11を含有し、その無機充填剤11が露出された微小溝12(単に「溝」ともいう)が当該溝付き樹脂成形品10の表面10aに複数形成されている。
樹脂の種類としては、レーザ照射又は化学処理等の樹脂除去手段により微小溝12を形成できるものであれば特に限定されない。例えば、レーザ照射により溝を形成できるものとして、ポリフェニレンスルフィド(PPS)、液晶ポリマー(LCP)、ポリブチレンテレフタレート(PBT)、ポリアセタール(POM)等を挙げることができる。
無機充填剤11は、溝付き樹脂成形品10を構成する樹脂の一部を除去して微小溝12を形成することで、その微小溝12に露出するものであれば特に限定されない。この無機充填剤11は、形成された微小溝12の側壁12aから微小溝12の空間内(溝内)に露出して、この溝付き樹脂成形品10と他の成形品20とで複合成形品1とする際に、それらの分離を抑制するアンカーの役割を果たす(図2参照)。また、このように無機充填剤11を微小溝12に露出させることで、無機充填剤11そのものが複合成形品1から脱落することを防ぐことができる。
なお、無機充填剤11を含有する樹脂材料として、ガラス繊維入りPPS(製品名:ジュラファイドPPS 1140A7,ポリプラスチックス社製)、ガラス繊維・無機フィラー入りPPS(製品名:ジュラファイドPPS 6165A7,ポリプラスチックス社製)、ガラス繊維入りLCP(製品名:ベクトラLCP E130i、ポリプラスチックス社製)等が市販されている。
微小溝12は、樹脂成形品10の表面10aに複数形成されたものであり、その側壁(側面)12aから無機充填剤11が露出されている。この微小溝12は、樹脂成形品10を構成する樹脂の一部を除去することによって形成され、このように樹脂の一部を除去することによって、無機充填剤11をその側壁12aから突出した状態で露出させることができる。
溝付き樹脂成形品10は、無機充填剤11を含有する樹脂成形品にレーザ照射や化学処理等を行って樹脂を部分的に除去し、その樹脂成形品の表面10aに複数の微小溝12を形成することによって得られる。溝付き樹脂成形品10では、このようにして樹脂成形品の表面10aを部分的に除去して微小溝12を形成することで、樹脂成形品内に含まれる無機充填剤11が微小溝12の側壁12aから露出される。
図2は、本実施の形態に係る複合成形品1の拡大断面の模式図である。図2に示すように、複合成形品1では、溝付き樹脂成形品10の微小溝12を有する面(表面10a)を接触面として、その面上に他の成形品20が隣接して配置されている。
ここで、他の成形品20としては、未硬化状態の場合に、無機充填剤11が露出された樹脂成形品10の微小溝12に入ることが可能なものであれば特に限定されるものではなく、例えば、硬化性樹脂(熱硬化性樹脂、光硬化性樹脂、放射線硬化性樹脂等)、熱可塑性樹脂等を挙げることができる。また、上述したような樹脂に限られず、ゴム、接着剤、金属等であってもよい。
複合成形品1は、上述したように、溝付き樹脂成形品10の微小溝12を有する面(表面10a)を接触面として、その面上に他の成形品20が隣接して配置されている。この複合成形品1は、例えば、多重成形(インサート成形)により得ることができる。
図4は、多重成形によって複合成形品1を得る方法を説明するための概略図である。図4に示すように、先ず、1次樹脂を1次成形して、溝付き樹脂成形品10の予備体10’を作製する(図4(1))。
