Description
・割れ43bが第2構造体41を通り、接合線42と平行に成長する(図1b)。このことは、第2構造体41の全体的な破壊を引き起こし、それが第2構造体の、第1構造体40との連携を停止する。一般に、この筋立ては破局的ではない。もしもフェイルセーフ設計原理が用いられる場合には、第2構造体41の破壊は、構造体の全体的な破壊を発生させず、この構造体は外部荷重に耐え続けることができる。
・割れ43cは、第2構造体41の外側表面に向けて成長し、そして消滅する(図1c)。この筋立ては、第2構造体41の全体的破壊を起こすか、またはその能力を部分的に低減させるかのいずれかである可能性がある。両方の場合において、第1構造体40は初期のままであるので、この筋立ては、全体の構造体の全体的な破局的破壊を起こしはしない。
・割れ43dは、第2構造体41の内部表面に向け、そして次いで第1構造体40を通って成長する(図1d)。この筋立ては、第1構造体40の破局的な破壊をもたらすので受け入れられないし、そして従って回避しなければならない。
複合材の層の積層体であって、複合材のそれぞれの層は、マトリックス中に埋め込まれた複数の強化繊維を含んでいる積層体;および
前記複合材の層の積層体の中に埋め込まれた自己修復性材料の1つもしくは2つ以上の層であって、自己修復性材料のそれぞれの層は、複数のコンテナを含んでおり、それぞれのコンテナは硬化性の修復性液体を含んでいる層、を含む複合材積層構造体を提供し、この積層体はT2の総厚さを有しており、そして自己修復性材料の層はT1の総厚さを有しており、そして比T1/T2は0.05未満である。
この比T1/T2を比較的に小さくすることによって、構造体の座屈性能に著しく有害な影響を有することなく、割れの成長を止めることができる。
好ましくは、この構造体は、更に複合材の複数の層を含む第2の積層体を含み、これらの積層体は互いに接合線で結合されている。
本発明の態様は、ここに添付の図面を参照して説明される。
・液相の、成長衝撃波の減衰(damping)によるエネルギーの吸収。
・固化、それによって、割れの成長によって破壊された材料を、固体接着剤系で置き換え、それによって材料の連続性とより円滑な荷重経路を確実にし、そして割れの先端における局部的な応力の集中を緩和する。
