Problems solved by technology

[0003] However, the products and manufacturing methods described in this publication are actually defective: due to the small size of the particles, usually only a few millimeters cubic, the sandwich structure formed by bonding is cut into granular dielectric material units At the same time, the foam material in the dielectric material unit is easily deformed, and the foam material and the conductive fiber are also easily separated after cutting, and the structural strength of the dielectric material is low.
In addition, this kind of production method of first overall production and then cutting requires a relatively large amount of cutting work in the later stage, and the requirements for cutting precision are also relatively high, which will eventually lead to an increase in production costs.
