Researchers are developing a material that does not react to heat

Researchers at the University of Southern California are working to create a material that does not react to heat. The project is already close to success, which could mean a real revolution in construction and mechanical engineering.

As you know, the vast majority of materials expand when heated, which creates many problems in the construction of engineering structures, in particular buildings and bridges. Particular attention has to be paid to structures made of several different materials that expand at different rates. To avoid undesirable consequences, it is necessary to create special built-in expansion joints that allow the structure to expand safely.

The university has developed technology to create 3D printed structures from several different materials. They are first printed in liquid form and then hardened by exposure to ultraviolet light.

Using this technology, an object with an internal lattice structure was printed, where the rays are located at specific angles. When heated, this structure, consisting of several materials, begins to expand in such a way that the rays are pulled inward. As a result, the object retains its original appearance.

The team hopes to create an affordable and easy-to-manufacture material that will be in demand in the construction of architectural structures.
