Technological method for prolonging storage period of automatically-formed core material

Abstract

The invention discloses a technological method for prolonging the storage period of an automatically-formed core material, and relates to the technical field of composite material manufacturing. The technological method comprises the following steps: S1, a core material storage mold is manufactured; S2, the filling core material is covered, wrapped and sealed through an isolation film, the sealed filling core material is placed in the core material storage mold, and then compaction treatment is conducted; and S3, the core material storage mold and the filling core material in the core material storage mold are integrally put into a freezer for storage, through the method, the filling core material can be stored for a long time, and the filling core material is taken out and unfrozen when needing to be used. Therefore, the method has the advantages that the storage period of the filling core material can be greatly prolonged, batch production can be realized, and the efficient production process requirement of the composite material is met.

Description

technical field [0001] The invention relates to the technical field of composite material manufacturing, in particular to a process method for extending the storage period of an automatically formed core material. Background technique [0002] In the production process of composite ribs and composite boards for curing and bonding, it is necessary to use automatically formed filling core materials (such as Figure 4 shown), the filler core material is generally carbon fiber prepreg. At present, there is no corresponding storage method for the automatically formed filling core material. After the filling core material is manufactured, it must be combined with the reinforced structure as soon as possible. If the external time is long, the manufacturability of the filling core material is poor, the molding quality is poor, the process window period is short, and the timeliness is short, so that the automatic forming filling core material cannot be produced in batches. Due to the...

Problems solved by technology

If the external time is long, the manufacturability of the filling core material is poor, the molding quality is poor, the process window period is short, and the timeliness is short, so that the automatic forming filling core material cannot be produced in batches. Due to the limitation of the storage problem of the automatic filling core material, it leads to A series of problems such as high production cost and low production efficiency
