Description
Technical Field
The invention belongs to the field of carbon fiber plate type integrated process, and particularly relates to an integrated forming preparation process of a large-size carbon fiber plate type workpiece.
Background
Along with the development of the space remote sensor towards the large caliber and long focal length, the space camera supporting structure adopting the traditional metal material can not meet the high stability requirement of guaranteeing the relative positions of all the optical elements borne by the space camera supporting structure under the limited weight constraint, so that the carbon fiber composite material is a novel aerospace material with good application prospect in the technical field of space remote sensing. Compared with the traditional material, the carbon fiber composite material has the advantages of small density, high specific strength and specific modulus, designable performance, good fatigue and vibration resistance, good high temperature and breakage resistance, easy processing and the like.
At present, two common technological schemes for carbon fiber plate-type workpieces are adopted, namely, the plate shell components are spliced through glue screws, the process is simple, the assembly stress for large-size plate-type workpieces is larger, and the method is suitable for structural components with low stability requirements; secondly, the carbon fiber plate-type workpiece is integrally formed, the conventional technology is a prepreg metal die-molding pressurizing technology, the technology is mature for small-size structural parts, but the curing pressure is insufficient for large-size carbon fiber plate frame parts, and the defects of layering, high porosity and the like are easily caused.
A common process scheme for large-size carbon fiber plate-type parts is a metal die-casting and mechanical pressurizing process, and the preparation flow is shown in fig. 1.

From the standpoint of cost and simplification of the process, large-size carbon fiber plate-type workpieces are usually subjected to mold clamping by mechanical pressurization, and the principle is that pressure is applied from the outer surface of a mold, and the pressure is transmitted to the center of the workpiece through a mold and a soluble core mold, so that the laid prepreg is compacted, and the side surface of the carbon fiber plate-type workpiece is subjected to mechanical pressurization as shown in fig. 3. In the actual production process, because the soluble core mould is not a rigid body, the pressure is gradually reduced from outside to inside, and the pressure disappears after a certain distance, as shown in the area of the dotted line in the center of the figure 3, the carbon fiber in the area is extremely easy to have defects of layering, dispersion, large porosity and the like, and the manufactured part is a defective product.
