Problems solved by technology

[0006] 1. Hand lay-up process requires less investment in equipment and good product appearance, but there are also the following problems: 1. Solvent volatilization pollutes the environment, and at the same time endangers health and is not environmentally friendly; 2. The bonding force between fiber material layers is not good, and the product strength is not high enough; 3. The curing process is slow and the production efficiency is low. Although the cost is low, it is easy for individuals to DIY production, but it is not suitable for mass production
[0007] 2. Core material molding process. The pressure of the product during molding comes from an external press, that is, the hard foam core material is used to outsource the cement layer and then the fiber prepreg is preformed. The hard foam materials used include PMI, PU, PVC, balsa wood, etc. need to be cut into pre-shaped core materials by CNC, put into the mold cavity, heated and pressurized, and the resin is cured and formed to obtain products. The efficiency is high. Existing problems: 1. The process is complex and rigid foam The core material needs to be cut by CNC in advance, which increases equipment investment. 2. The foam material and fiber prepreg must be additionally added with a cement layer, which increases the material cost. 3. Due to uneven force, it is difficult to obtain an excellent product appearance; 4. The core material is in the There is no expansion force from the inside to the outside in the molding process, so the interlayer bonding force of the fiber is not good, the bonding is uneven, and the overall strength of the product is easily delaminated; 5. Large-sized workpieces require large-tonnage presses. Large investment in equipment is not conducive to popularization
This method can realize the hollow structure of the mechanical arm by blowing air in the middle of the nylon air pipe. There are problems at this stage: 1. Air blowing and hot pressing molding. In this industry, there is a 3-5% defective rate due to air leakage; 2. The investment of air blowing equipment is required; 3. The non-stereoscopic support structure of the preform obtained by wrapping the high-energy adhesive with fiber prepreg makes it difficult to control the product size stably, and it is easy to cause defective rates such as dislocation of the fiber layup in the final product; 4. It belongs to the intermittent production mode, and the production efficiency is low; 5. Due to the limitation of the shape of the air duct, it is difficult to apply complex products
