提高碳纤维强度的理论基础及其技术途径

Theoretical basis and technical path of increasing strength of carbon fiber

碳纤维属于脆性材料。它的抗拉强度受控于各类缺陷，基本遵循 Griffith 经典理论和韦氏（Weibull）统计规律。如何减小缺陷尺寸、减少缺陷数目是当今提高其抗拉强度的主要技术途径和研究热点。

Carbon fiber belongs to brittle materials.Its strength is controlled by various defects,follows griffith classical theory and weibull statistical regularity basically.The main technical path and research focus of increasing its strength are how to minish dimension of defects and how to reduce number of defects.
