A resin matrix with strong microwave absorption and a preparation method thereof belong to the field of composite materials. The invention selects high-performance epoxy resin with strong polarity as the main resin, adds microwave absorbing components to adjust the microwave responsiveness and viscosity of the resin system to adapt to liquid molding such as winding, and selects a curing agent to adjust the microwave response activity of the resin system. And to achieve its mechanical properties, heat resistance and dimensional stability, on the basis of which the ionic liquid is used to modify the nano-components to further enhance the microwave responsiveness of the resin matrix. By adjusting the structure of the main resin, the microwave absorbing component, the curing agent and the ionic liquid-modified nano-component and their mixing ratio, a kind of microwave absorbing performance, good dispersion of the nano-component, suitable viscosity and uniform curing was developed. , Microwave curing resin system with excellent comprehensive mechanical properties, good heat resistance and high dimensional stability. It has great guiding significance for the preparation of fiber composite materials, and can be widely used in aerospace and other fields. |
