We must first understand the prepreg equipment:
Prepreg refers to a composition formed by impregnating fiber or fabric materials with resin under certain conditions. It is also an intermediate material for composite material manufacturing. It has certain mechanical properties and can be used for structural design. In the manufacturing process of composite materials, some characteristics of prepreg will be directly transplanted into the composite material. In other words, the quality of prepreg directly affects the quality of composite materials.
Characteristics of prepreg:
1. Prepreg can control the resin content during the molding process to obtain a finished product with very good mechanical properties and dimensions.
2. Prepreg is a dry material with a certain viscosity, so it can be layered more accurately.
3. There are no bubbles inside, which can form a good surface effect.
4. The production environment is clean and tidy, which is more environmentally friendly than the traditional composite material processing environment.
5. The disadvantage is that the production process is complicated and the price is high.
Application fields of prepreg:
Due to the easy-to-control characteristics of prepreg, it is widely used in sports goods, aerospace materials, military products, construction products, automobile manufacturing, mobile phone manufacturing, ship materials, nuclear power engineering, agricultural breeding and other fields. .
Prepreg cutting equipment:
Prepreg is widely used, but no matter what industry it is used in, it is inseparable from the cutting process. Prepreg cutting is now often used. Of course, some simple straight or rectangular manual cutting is basically satisfactory except for the slow speed. But for complex special-shaped cutting, it cannot fully meet the requirements.
Automatic feeding vibration knife cutting machine can automatically feed and automatically layout.
The first is accuracy. Many industries that use prepreg have very high requirements for the cutting accuracy of prepreg, which cannot achieve the cutting accuracy of manual cutting.
The automatic feeding vibration knife cutting machine adopts servo motor and cooperates with the self-developed multi-axis control system to make the cutting accuracy higher.
Its second is the speed requirement. The speed of manual cutting, even for decades of skilled workers, is far behind the speed of machine cutting.
The cutting speed of the vibration knife cutting machine can reach 140m/min, which is 5-8 times that of manual cutting. It can cut continuously and greatly increase the output.
. The important thing is the cutting cost. On the one hand, it is the workers' wages. For skilled workers, it costs at least nearly $100,000 per year. On the other hand, there is a serious waste of hand-cut materials.
According to the type, it can be divided into unidirectional carbon fiber prepreg and woven carbon fiber prepreg. The former has a large strength in the fiber direction and is usually used for laminates that require a combination of different directions; the latter has different weaving methods, and the strength in the two directions is almost the same, which can be applied to different structures.
By the way, the myocardial infarction characteristics of carbon fiber prepreg are divided into three points: .. The first point is high strength and low density. The strength of carbon fiber prepreg can reach 6-12 times that of steel, but the density is only one-fourth of steel; the second point is good plasticity, easy to shape and easy to process; the third point is corrosion resistance and long life.
It is usually widely used in aerospace, fishing tackle, sports equipment, sporting goods and other fields. Military products.
There are two main methods for the production of carbon fiber prepreg, one is the hot melt method and the other is the solution impregnation method. Both methods have advantages and disadvantages. Like the hot melt method, the resin is directly heated. Because the resin content is easy to control, there is no solvent residue. However, due to the high viscosity of the resin, it is easy to cause fiber deformation when impregnating fiber braids. Therefore, in order to use this method well, it is necessary to control the viscosity of the resin. The solvent impregnation method has low investment cost and simple production process, but the solvent used is easy to remain in the prepreg, which is not only easy to cause environmental pollution, but also may affect the strength of the material.
