Embodiment 1
[0039] see figure 1 , in an embodiment of the present invention, a process for fabricating a fiber-reinforced composite sheet with ribs by paving method includes the following steps:
[0040] (1) Stir the base material evenly in the base material mixing station 13, then put it into the primary paver 14, and spread the base material in the mobile mold to form a layer of base material layer 1;
[0041] (2) Stir the fabric evenly in the fabric mixing station 23, then put it into the secondary paver 24, and spread the fabric flat on the bottom material layer 1, and spread it into a layer of fabric layer 2;
[0042] (3) Then, the bottom material layer 1 and the fabric layer 2 are sent into the initial curing kiln 4 by a conveyor belt, and steam initial curing is carried out. The steam initial curing condition is: temperature 50-100 ° C, time 2-5 minutes, so that the material is initially set to It is beneficial to move when stacking, and stack the plates after leaving the kiln;

Embodiment 2
[0048] In an embodiment of the present invention, a process for fabricating a fiber-reinforced composite sheet with ribs using a paving method includes the following steps:
[0049] (1) Stir the base material evenly in the base material mixing station 13, then put it into the primary paver 14, and spread the base material in the mobile mold to form a layer of base material layer 1;
[0050] (2) Putting mesh ribs or strip ribs 3 made of metal or non-metallic materials on the bottom material layer;
[0051] (3) Stir the fabric evenly in the fabric mixing station 23, then put it into the secondary paver 24, and spread the fabric flat on the bottom material layer 1, and spread it into a layer of fabric layer 2;
[0052] (4) Then the bottom material layer and the fabric layer are sent to the initial curing kiln 4 by a conveyor belt for initial steam curing. The conditions for the initial steam curing are: the temperature is 50-80°C, and the time is 2-5 minutes, so that the material...
Embodiment 3
[0056] In an embodiment of the present invention, a process for fabricating a fiber-reinforced composite sheet with ribs using a paving method includes the following steps:
[0057] (1) Stir the base material evenly in the base material mixing station 13, then put it into the primary paver 14, and spread the base material in the mobile mold to form a layer of base material layer 1;
[0058] (2) Putting mesh ribs or strip ribs 3 made of metal or non-metallic materials on the bottom material layer;
[0059] (3) Repeat steps (1) and (2) multiple times;
[0060] (4) Stir the fabric evenly in the fabric mixing station 23, then put it into the secondary paver 24, and spread the fabric flat on the bottom material layer 1, and spread it into a layer of fabric layer 2;
[0061] (5) Repeat steps (2) and (4) multiple times;
[0062] (6) Then the bottom material layer and the fabric layer are sent to the initial curing kiln 4 by a conveyor belt for initial steam curing. The steam primar...
