Description
SiC粉末(信濃電気製錬株式会社製のGP#500、 平均粒径30μm)100質量%に有機バインダとしてフェノール樹脂粉末(DIC株式会社製のOI−305A)を15質量%添加し、ヘンシェルミキサーを毎分1500回転で4分間運転させて混合した。
比較例1として、フェノール樹脂粉末の添加量を変更してSiC/Si複合材料体のSiC充填率を25体積%とした以外は実施例と同様にして、中空構造のSiC/Si複合材料体の作製を試みた。しかし、SiC/Si複合材料体とSiCチューブとの界面にクラックが発生した。なお、SiC/Si複合材料体の熱膨張係数は2.43×10−6[1/K]であった。
比較例2として、SiCチューブを埋め込まなかったこと以外は実施例と同様にして、中空構造のSiC/Si複合材料体の作製を試みた。しかし、溶融Siの浸入によって、SiC/Si複合材料体の中空部が閉塞した。
Claims (3)
- SiC多孔質体の接着面に形成した溝に、内部空間を有し、前記SiC多孔質体より気孔率が低いSiC体を埋め込み、前記SiC多孔質体同士を接着させた後、金属Siを含浸させてSiC充填率が30体積%〜95体積%である中空構造のSiC/Si複合材料体を得ることを特徴とするSiC/Si複合材料体の製造方法。
- 前記SiC体の気孔率は5%以下であることを特徴とする請求項1に記載のSiC/Si複合材料体の製造方法。
- 内部空間を有するSiC体が内部に埋め込まれ、SiC充填率が30体積%〜95体積%であり、前記SiC体の空孔及びSiが占める体積割合と比べて空孔及びSiが占める体積割合が高いことを特徴とするSiC/Si複合材料体。
