AI Technical Summary
Technical Problem
Existing composite materials with multiple voids, such as foamed materials, do not effectively consider the relationship between the distribution of void sizes and thermal conductivity, limiting their thermal conductivity improvement.
Method used
A composite material is designed with a specific distribution of void sizes having two or more peaks, where inorganic particles are arranged along the boundaries between voids and a skeletal structure, enhancing thermal conductivity and flexibility.
Benefits of technology
The material achieves high thermal conductivity and flexibility by optimizing void size distribution and particle arrangement, surpassing conventional foamed materials in thermal performance.

Abstract
A composite material 1a includes: a framework 10 that includes a resin 11; inorganic particles 12; and voids 20. At least a portion of the inorganic particles 12 are arranged along the boundaries between the framework 10 and the voids 20. A number-based first size Sz distribution D1 obtained by measuring the size Sz of each of the voids 20 in a cross-section of the composite material 1a has at least two peaks.
