Single crystal α－ Interlaminar hybrid composite material based on Al2O3 Fiber and its preparation method

摘要

Embodiments of the present invention include single crystals α－ The above-mentioned single crystal containing Al2O3 Fiber, glass fiber and resin phase solvent α－ The hybrid ratio between the Al2O3 Fiber and the above glass fiber is 1:40 to 3:53 α－ An interlaminar hybrid composite material based on Al2O3 fibers and its preparation method are disclosed.The composite material has a single crystal α－ By controlling the addition ratio of Al2O3 Fiber and glass fiber, excellent mechanical properties can be maintained in high temperature, and tensile strength can be remarkably improved, and it can be applied to the manufacture of heat resistant parts in the inferior environment such as aerospace products.Diagram
