Problems solved by technology

[0003] Although some composite materials in the prior art are better used in normal working environments and temperatures, for some composite materials that require high toughness, the existing composite materials will undergo high deformation and even fracture during use. problem, which seriously affects the service life of this type of composite material
In some occasions where the working temperature is lowered, such as composite materials used in high-temperature and low-temperature equipment such as refrigerators, if they cannot withstand low temperatures, it will cause damage to the equipment and affect its use.
