Carbon fiber piano boxes have many advantages, most notably high strength and light weight. Compared to carbon fiber materials with the same volume of steel, the weight of carbon fiber is only a quarter of that of steel, but its strength is several times that of it. Carrying the piano in a carbon fiber case with you almost always feels the weight of the box, and if you collide with other things while walking, there won't be any damage. The corrosion resistance, the erosion of acid and alkali solutionsof carbon fiber is also excellent.
