| 5. | But it is mainly dependant on the physical parameters such as volume shrinkage . and when phbv crystallized , the hv content will be segregated , it will be accelerated when crystallization temperature is increased
在结晶过程中， phbv二元共晶中hv (羟基戊酸)组分会受到排斥，结晶温度的升高会导致hv组分分凝现象的加剧。 |

| 8. | The mechanism of physical damage of carbon fibers was clarified firstly . the precursor which attached on carbon fibers changes to inorganic ceramic under high temperature with large volume shrinkage which appearing at cracks with fiber traction and the cracks are mainly vertical to fiber axis . because of mismatched coefficients of thermal expansion , carbon fibers suffer multiple thermal stresses and are damaged
首次探明了碳纤维热应力物理损伤机制，即碳纤维表面附着的先驱体在高温下无机化形成陶瓷体，同时伴随着大的体积收缩，在碳纤维的牵引下，基体的体积收缩以开裂形式出现，裂纹的取向以垂直于纤维轴向为主，由于碳纤维与基体热膨胀系数失配，致使碳纤维在降温过程中受到复杂热应力，引起碳纤维损伤。 |
