本文研究了碳纤维增强酚醛聚合物烧蚀材料在快速加热作用下的局部离面变形。利用三维数字图像相关技术测量了高温下的局部离面变形。这是通过使用陶瓷粘结剂在样品表面附着耐高温随机图案来实现的。此外，还使用了蓝色滤光片，以切断样品的强红外辐射。然后从碳化、热解气体产生、气体压力储存和气体压力引起的层间脱粘等方面讨论了快速加热条件下局部离面变形的机理。
This study investigates local out-of-plane deformation of a carbon fiber reinforced phenolic polymer ablator subjected to very rapid heating. Local out-of-plane deformation was measured using a three-dimensional digital image correlation technique at high temperatures. This was achieved by attaching high temperature resistant random patterns on the specimen surface using a ceramic bond. Additionally, blue filters intended for cutting strong infrared radiation from the specimen were also used. This study then discusses the mechanisms of the local out-of-plane deformation under rapid heating conditions in terms of carbonization, pyrolysis gas occurrence, gas pressure storage, and interlaminar debonding due to gas pressure.
