Problems solved by technology

The weight of the layer completed by this method can reach about 10 tons, which greatly limits the speed of the high-speed yacht.
At the same time, due to the hand lay-up, the labor intensity is high, and the product quality is too dependent on the technology of each operator, resulting in low performance stability
Moreover, in this production process, the emission of styrene is large, and the labor hygiene conditions are poor.

Embodiment 1

[0016] The invention provides a vacuum infusion and infiltration molding process for high-speed yachts, the steps of which are as follows:

[0017] Step 1. Clean the hull mold and wax and polish it;

[0018] Step 2. Spray surface paint with a thickness of 3 to 5 mm on the surface of the waxed and polished hull with a pressure-free spraying device;

[0019] Step 3. First, spray the mixture of resin and glass fiber on the surface of the hull mold obtained in step 2 to reinforce the base layer. The spray thickness is 2-3mm, and then use the pressure-free spraying device to spray the glass fiber reinforced plastic coating. The spray thickness is 3-6mm. Wherein, the weight ratio of resin and glass fiber in the resin and glass fiber mixture is 1, resin is, the weight ratio of resin and glass fiber in the fiberglass coating is 1, and resin is ortho-phthalic low-viscosity resin;

[0020] Step 4, manually laying up cloth felt on the coating, the total thickness of the felt is 10mm, th...

Embodiment 2

[0026] The difference between this embodiment and embodiment 1 is that in step 3, the weight ratio of resin and glass fiber in the resin and glass fiber mixture is 0.7, and the weight ratio of resin and glass fiber in the fiberglass coating is 0.7;

[0027] In step 4, the total thickness of the felt is 20mm. The felt is a composite board with grooves on both sides in the direction of length and width. The groove spacing is 18mm and the depth is 3mm. The diameter is 3mm.

[0028] Take column test, measured by tensile, bending and impact methods, the strength is beyond the standard specification, which can fully meet the required value.

Embodiment 3

[0030] The difference between this embodiment and embodiment 1 is that in step 4, the felt is a composite board with grooves on both sides in the direction of length and width, the groove spacing is 22mm, and the depth is 2mm. At the same time, holes are punched in the grooves. The diameter is 1mm. Other steps in this embodiment are the same as in Embodiment 1. Take column test, measured by tensile, bending and impact methods, the strength is beyond the standard specification, which can fully meet the required value.

Abstract

The invention provides a vacuum perfusion infusion forming technique used for a speedboat, which comprises the steps of: cleaning, waxing and polishing a speedboat shell die at first, coating surface paint with the thickness of 0.6-1mm, then reinforcing a basic layer and coating glass fiber reinforced plastic with the coating thickness of 2-3mm, manually laminating a cloth felt on the coating, and then covering a diversion net, a demoulding cloth and a plastic cement cloth on the felt in sequence, respectively connecting one ends of a vacuumizing pipe and a resin diversion pipe on the diversion net and arranging the other ends outside, injecting resin after vacuumizing, and demoulding after forming. The vacuum perfusion infusion forming technique used for the speedboat has the advantages of reducing the weight of the original layer by 30 percent, reducing the emission of styrene by 90 percent, reducing the cycle time by 50 percent and reducing the labor cost by 30 percent, greatly improves the flow speed and has stable product performance.

Description

technical field [0001] The invention relates to a vacuum infusion forming process, which is used for the hull laying of high-speed yachts, and belongs to the technical field of vacuum infusion forming process for the hull laying of high-speed yachts. Background technique [0002] The traditional craft of high-speed yacht hull laying is to clean the hull mold first, wax and polish it, then spray gel coat on the hull mold and then lay 18 layers of FRP by hand lay-up, thus completing the hull structure. The weight of the layer completed by this method can reach about 10 tons, which greatly limits the speed of the high-speed yacht. At the same time, due to the hand lay-up, the labor intensity is high, and the product quality depends too much on the skills of each operator, resulting in low performance stability. Moreover, in this production process, the emission of styrene is large, and the labor hygiene conditions are poor. Contents of the invention [0003] The object of t...
