AI Technical Summary

Technical Problem

Existing heat insulation structures, such as those using styrene foam or vacuum insulating materials, are heavy due to the need for metal reinforcement, compromising their lightweight and strength characteristics.

Method used

A heat insulation structure comprising a flat base material and a plate-shaped reinforcing member with protrusions supported by the base material, both made of composite materials, and a vacuum-sealed laminate configuration to enhance insulation and strength.

Benefits of technology

The structure achieves lightweight thermal insulation with enhanced strength and improved thermal performance by using composite materials and vacuum-sealed spaces, reducing contact areas and heat transfer.
