Description
1.少なくとも樹脂、ガラス繊維およびレーザ吸収材を含有し、該ガラス繊維が露出した溝を有する溝付きの第1の樹脂成形品と、
該第1の樹脂成形品の該溝を有する面上に隣接して配置される第2の成形品、
とを備えた複合成形品であって、
該第1の樹脂成形品において、該ガラス繊維は、該樹脂組成物全体に対し12〜45質量%が混合され、
該レーザ吸収材は、該樹脂組成物全体に対し0.25〜10質量%混合されており、かつ、[{第1の樹脂成形品を構成する樹脂組成物に含有されるガラス繊維の量(質量%)×0.9}+{第1の樹脂成形品を構成する樹脂組成物に含有されるレーザ吸収材の量(質量%)×1.4}]×{第2の成形品を構成する材料の溶融粘度(Pa・s)+360}÷{第1の樹脂成形品を構成する樹脂組成物に含有されるガラス繊維の平均直径(μm)×0.8}が、700以上2500以下を満たす、複合成形品。
3.{前記第1の樹脂成形品を構成する樹脂組成物に含有される前記ガラス繊維の量(質量%)×0.9}+{前記第1の樹脂成形品を構成する樹脂組成物に含有される前記レーザ吸収材の量(質量%)×1.4}]×{前記第2の成形品を構成する材料の溶融粘度(Pa・s)+360}÷{前記第1の樹脂成形品を構成する樹脂組成物に含有される前記ガラス繊維の平均直径(μm)×0.8}が1200以上2100以下を満たす、前記1又は2に記載の複合成形品。
本発明の複合成形品は、少なくとも樹脂、ガラス繊維およびレーザ吸収材を含有する樹脂組成物からなり、該ガラス繊維が露出した溝を有する溝付きの第1の樹脂成形品と、該第1の樹脂成形品の該溝を有する面上に隣接して配置される第2の成形品、とを備えた複合成形品であって、該第1の樹脂成形品において、該ガラス繊維は、該樹脂組成物全体に対し12〜45質量%が混合され、該レーザ吸収材は該樹脂組成物全体に対し0.25〜10質量%混合されており、かつ、[{第1の樹脂成形品を構成する樹脂組成物に含有されるガラス繊維の量(質量%)×0.9}+{第1の樹脂成形品を構成する樹脂組成物に含有されるレーザ吸収材の量(質量%)×1.4}]×{第2の成形品を構成する材料の溶融粘度(Pa・s)+360}÷{第1の樹脂成形品を構成する樹脂組成物に含有されるガラス繊維の平均直径(μm)×0.8}が700以上2500以下を満たすことを特徴とする。
図2は、溝付きの第1の樹脂成形品10の概略拡大断面模式図である。溝付きの第1の樹脂成形品10は、ガラス繊維11を含有する。また、溝付きの第1の樹脂成形品10は、ガラス繊維11が側面より突出し露出された溝12を有する。ガラス繊維の一部は、溝に架かっている。
[樹脂]
[ガラス繊維]
[レーザ吸収材]
質量%含有させることにより、レーザ照射時の樹脂の除去しやすさ(溝の形成しやすさ)を適宜調整することができ、接合強度のバラツキを抑制することができる。0.25質量%よりも少ない場合は、ガラス繊維によるレーザの反射や散乱による減衰が発生しやすく、溝の形成状態にバラツキを発生しやすくなり、10質量%を超えた場合は、レーザ吸収材の凝集物が生じたり、またレーザ吸収材が凝集し高濃度となった箇所で、レーザによる過熱が発生し炭化物が生成したりすることで、それらが異物として破壊起点となり、やはり接合強度のバラツキを発生しやすくなる。
[溝]
本明細書では、複合成形品1においてガラス繊維11が露出されていない場合であっても、複合成形品1から第2の成形品20を取り除いた態様において溝12からガラス繊維11が露出していれば、「溝12においてガラス繊維11が露出されている」ものとする。
本発明の第2の成形品20を形成する材料は、未硬化の流動状態であって、ガラス繊維11が露出された溝12に入ることが可能な樹脂であれば特に限定されるものでなく、熱可塑性樹脂、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)、ゴム、接着剤等のいずれからなるものであってもよいが、加工性の点から、射出成形で賦形することができる熱可塑性樹脂、熱硬化性樹脂、ゴムを含む樹脂組成物が好ましく、熱可塑性樹脂を含む熱可塑性樹脂組成物であることがより好ましい。第1の樹脂成形品を構成する樹脂と同種の樹脂または異種の樹脂を使用することもできる。ここで異種とは、第1の樹脂成形品を構成する樹脂を、一部含む場合も含んでいる。本発明では、異種の場合に特に効果が発揮される。
第1の樹脂成形品に第2の成形品が射出成形、トランスファ成形、溶着等の方法により積層されることにより、本発明の複合成形品が形成される。
本発明では、溝付きの第1の樹脂成形品を構成する樹脂組成物に含有されるガラス繊維の含有量と平均直径、レーザ吸収材の含有量、および第2の成形品を構成する材料の溶融粘度が、得られる複合成形品の接合強度に相互に影響を及ぼす。
