Abstract
A composite containing hollow ceramic spheres and a preparation method are provided. The composite includes an impact-resistant gradient complex part containing a hollow ceramic sphere complex, prepared by using a 3D printing method and a hollow ceramic sphere-high polymer complex dielectric material obtained in a blending and fusing way. The obtained composite has the characteristics of relatively low density and high strength. The impact-resistant gradient complex part is a layered complex, the composition and properties of the complex may be regulated in a direction vertical to a layer according to a design, for example, mechanical properties of the complex are transitioned from soft to hard to form gradient change by regulating the change of the composition, and meanwhile, the thickness among layers with different properties is accurately controlled as required. The dielectric, heat conducting and mechanical properties of the hollow ceramic sphere-high polymer complex dielectric material are greatly improved.
