The effect of whisker growing catalyzed by different amounts of AlF₃ on the various properties of an epoxy/silicone resin-based high-temperature-resistant adhesive was comprehensively investigated. Although the addition of AlF₃ promoted the oxidation reactions, accelerated the premature formation of mullite whiskers, increased the production of SiC ceramic, and reduced the thermal expansion of bonding layer, the excessive use of AlF₃ induced many more large holes in the bonding layer, caused the structural heterogeneity, and made mullite whiskers overgrow, thus finally led to the weaker mechanical properties of adhesives. The best dosage of AlF₃ in this work was 3 % (mass fraction), a uniform composite structure that whisker weaved adhesive frame kept steady from 1100 °C to 1500 °C, and an impressive bonding strength of 63 MPa was achieved at 1100 °C, 80 % higher than that of the blank sample. Under the synergistic effect of whisker repair, whisker bridging, whisker drawing and crack deflection, a multi-stage fracture phenomenon happened during the shear test, and the fracture displacement of 1100 °C-calcined adhesive with 3 % AlF₃ increased by 61 %, compared with that of the black sample.

全面研究了不同数量的AlF ₃催化的晶须生长对环氧/硅氧烷树脂基高温胶粘剂各种性能的影响。尽管添加AlF ₃促进了氧化反应，加速了莫来石晶须的过早形成，增加了SiC陶瓷的生产，并降低了粘结层的热膨胀，但是过量使用AlF _3会在粘结层中产生更多的大孔引起结构异质性，并使莫来石晶须过度生长，最终导致胶粘剂的机械性能较弱。最佳剂量的AlF ₃在这项工作中，其质量分数为3％，晶须编织的粘合框架在1100°C至1500°C的温度下保持稳定的均匀复合结构，在1100°C时达到了63 MPa的惊人粘合强度，比80％高出80％。空白样品的值。在晶须修复，晶须桥接，晶须拉伸和裂纹变形的协同作用下，剪切试验过程中发生了多阶段断裂现象，含有3％AlF ₃的1100°C煅烧粘合剂的断裂位移增加了61％，与黑色样品相比。
