原子炉材料照射試験において、照射容積、放射化、廃棄物等の問題から微小試験片技術開発が極めて有効だが、複合材料は有限の大きさの複数要素からなる不連続構造に由来する異方性のため、試験片小型化に伴う破壊の特徴を熟慮した評価法の開発が重要である。本稿では、様々な試験モードによる複合材料の破壊挙動に関する最近の成果を交え、微小試験片を用いた複合材料のための強度試験法の特徴と課題を整理し、試験法規格化を見据えた微小試験片法の開発に関する今後の展望を試みた。

The small specimen test technique is a viable method for nuclear reactor materials irradiation because of reducing irradiation volume, radioactivity, and waste. It is important to develop the evaluation method to consider unique failure behavior of composites since composites generally show anisotropy due to discontinuity among various constituents with finite size. This paper reviewed recent progress of failure evaluation by various modes and summarized requirements and issues about the small specimen test techniques for composites. Finally, we discussed future perspectives of the small specimen test techniques toward standardization.
