A process for reinforcing blocks of stone material, in particular extracted from a quarry, comprises the following operative steps: preparing a block of stone material to be treated on a mobile carriage; spreading on said block a layer or film of suitable resin by means of spraying; stretching over the entire surface of the said resin block a reinforcing fabric or fibre layer; and removing the so reinforced block from said carriage after a preset time.

This application provides a 5D ceramic housing structure and a 5D ceramic processing process method, to resolve a problem that long processing time of existing CNC and polishing results in high production costs of a housing of an electronic device and low production efficiency. The method includes: obtaining a raw ceramic material, that is, a ceramic powder; performing casting processing on the raw ceramic material to obtain a to-be-sintered green-state ceramic sheet; performing flat ceramic sheet pre-sintering on the green-state ceramic sheet to obtain a sintered product with a shrinkage rate of 18% to 23%; performing 5D heat-bend forming on the sintered product, to enable the sintered product to be further crystallized and deformed by heating to form a ceramic housing; performing fiber adhesion on the ceramic housing; and forming a 5D ceramic housing structure.
