The invention discloses a
digital manufacturing method for light permeable concrete. The method comprises the following steps that the density, array
modes and patterns of optical fibers are designed through
computer aided software; light guiding fibers are fixed to two
optical fiber substrates in a penetrating-inserting mode through a braiding mechanism and a
wire drawing mechanism, and different arrangement
modes and separation distances of the optical fibers are achieved through stepping displacement of the two assembled
optical fiber substrates; the optical fibers in certain lengths are reserved, the upper
optical fiber substrate and the lower optical
fiber substrate are separated after optical
fiber arrangement is completed, and the near optical fibers are bonded into bundles through a binder so as to improve the
mechanical strength of the optical fibers and protect the surfaces of the optical fibers; and the optical
fiber substrates with the optical fibers arranged in advance are placed in a mold for concrete pouring and forming, and then cured to the demolding period, and the optical fiber substrates and the superfluous optical fibers are ground to obtain the light permeable concrete. The computer
numerical control technology is firstly adopted for the optical fiber arrangement process of the light permeable concrete, and automatic rapid production of the light permeable concrete can be achieved.
