Embodiment 1

[0042] The S-shaped glass inorganic reinforcing fiber with a fiber diameter of 3µm is fed into a tunnel with a length of 18 meters, a width of 200mm, and a height of 300mm. An automatic spraying device with a length of 200mm and a width of 1mm is installed at the entrance of the tunnel to spray out water containing 0.6%wtγ-shrinkage Anhydrous alcohol solution of glyceryl ether oxypropyltrimethoxysilane, and at the same time input nitrogen gas (N 2 ), install an exhaust fan at the exit of the corridor, and extract the N 2 After being separated from the anhydrous alcohol by the cooling tower, it can be recycled. After the inorganic reinforcing fiber is processed by the tunnel, it is immediately input into the cooling tunnel of the same size, and at the same time, the dry air at room temperature containing 0.001% v / v water vapor is input at a distance of 0.3 meters from the tunnel. An exhaust fan is installed at the exit of the tunnel to extract the dry air out of the tunnel for ...

Embodiment 2

[0045] Enter E-type glass inorganic reinforcing fibers with a fiber diameter of 6µm into a tunnel with a length of 18 meters, a width of 200mm, and a height of 300mm, and install an automatic spraying device with a length of 200mm and a width of 1mm at the entrance of the tunnel to spray 0.8%wtγ-glycidol Anhydrous alcohol solution of etheroxypropyl trimethoxysilane, and at the same time input nitrogen gas containing water vapor 0.03% v / v at a temperature of 160°C at a distance of 0.8 meters from the shaft (N 2 ), install an exhaust fan at the exit of the corridor, and extract the N 2 After being separated from the anhydrous alcohol by the cooling tower, it can be recycled. After the inorganic reinforcing fiber is processed by the tunnel, it is immediately input into the cooling tunnel of the same size, and at the same time, it is input into the dry air at room temperature containing 0.003% v / v water vapor at a distance of 0.3 meters from the tunnel. Install an exhaust fan at t...

Embodiment 3

[0048] Alumina ceramic inorganic reinforcing fibers with a fiber diameter of 4µm are fed into a tunnel with a length of 18 meters, a width of 200mm, and a height of 300mm. An automatic spraying device with a length of 200mm and a width of 1mm is installed at the entrance of the tunnel, and sprays water containing 0.7%wtγ-shrinkage Anhydrous alcohol solution of glyceryl ether oxypropyltrimethoxysilane, and at the same time input nitrogen gas (N 2 ), install an exhaust fan at the exit of the corridor, and extract the N 2 After being separated from the anhydrous alcohol by the cooling tower, it can be recycled. After the inorganic reinforcing fiber is processed by the tunnel, it is immediately input into the cooling tunnel of the same size, and at the same time, the dry air containing water vapor 0.002% v / v at room temperature is input at a distance of 0.3 meters from the tunnel. An exhaust fan is installed at the exit of the tunnel to extract the dry air out of the tunnel for re...

Description

technical field [0001] The invention belongs to the field of production and application of special fiber composite materials, and in particular relates to a manufacturing method of inorganic reinforced fiber laminated materials. Background technique [0002] Fiber-reinforced resin-based composites were first developed in the United States in the 1930s. At that time, composite products were mainly to meet the needs of military and aerospace fields. In recent years, due to the many advantages of fiber thermoplastic composite materials, people began to shift the focus of research to fiber reinforced thermoplastic or / and thermosetting composite materials, and began to conduct continuous and in-depth research on this type of material. The output of fiber thermoplastic composite materials has gradually increased, and processing There are also endless ways, and fiber-reinforced thermoplastic or / and thermosetting composite materials have been applied in many fields, such as aerospac...
