摘要
研究了液相浸渍及化学气相法致密工艺对二维炭 炭 (2D C C)复合材料力学性能的影响 ,尤其是对层间剪切强度 (ILSS)的影响。结果表明 :液相浸渍法增密周期短且致密效果好 ,但材料强度不高 ;而化学气相沉积(CVD)致密周期长 ,但材料层剪强度高 ;采用两种工艺联合致密 ,材料界面结合强度适中 。
Influence of CVD and LIC densification processes on mechanical properties, especially interlaminate shear strength(ILSS) of carbon cloth reinforced 2D C/C composites is studied. It is shown that the densification period of CVD process for 2D C/C is longer, but bonding strength of interface between fiber and matrix of composites is stronger, compared with LIC process, while the combined process (LIC+CVD) is good for the preparation of 2D C/C with good interface properties and high ILSS.
