Fiberglass composite mobile phone back covers become the new trend?

  Subsequently, many new phones were equipped with composite back covers, especially those that needed to be lightened and thinned, but the fiberglass was also made to have a texture close to that of glass.

  Xiaomi Mi MIX Fold 4 is available in four colors: black, white, gentian blue, and dragon scale fiber version. The black, white and gentian blue versions are made of ultra-thin fiberglass technology, which is lightweight and more than 30% thinner than traditional glass. The back cover of the dragon scale fiber version adopts a five-layer composite structure, combining aramid fiber and ceramic fiber to achieve optimal strength and toughness. It achieves puncture resistance and impact resistance in the three directions of XYZ, which can be said to increase strength while reducing weight.

  According to previous reports, more than one of the upcoming Snapdragon 8 Gen4 flagships will use a composite glass body. The report also said that the body materials of the new batch of iterative new phones are very rich, including but not limited to plain leather, fiberglass, glass, traditional ceramics, and new ceramics.
