Abstract
The present invention is a kind of Resin film infusion of FRP moulds, is comprised the step of：The first step, mold material selection, design and preparation；Second step, RFI shapings；3rd step, heating cloth are pre-buried.A kind of Resin film infusion of FRP moulds of the present invention, described can both avoid temperature too high, and mold materials occurrence of large-area is deformed and burnt, and can prevent that temperature is too low again, and the resin heated time of mold cavity surface is long, and resin film melting infiltration is difficult.
Description
Technical field
The present invention relates to the Resin Film Infusion field of mould, more particularly to a kind of Resin film infusion of FRP moulds.
Background technology
Resin film infusion (RFI) has obtained more and more extensive answer with its plurality of advantages in Aeronautics and Astronautics field
With.As foreign countries have prepared the wing structure of commercial transport and the radome fairing country RFI techniques of business aircraft with RFI techniques
Prepare large-size components and be also not seen reported the research for being limited only to resin film.National University of Defense technology's space flight at present and material engineering
Institute has carried out feasibility analysis and have developed RFI having prepared entirety with resin film to preparing large-scale train component using RFI techniques
It is molded the FRP moulds of roof of train and success is achieved in actual production.
RFI is a kind of inexpensive composite technology of preparing.It is better simply to be currently used primarily in the big-and-middle-sized and shape of manufacture
The mechanical property of composite element such as its component such as bullet train drivers' cab and unmanned plane whole wing is pasted than hand or vacuum bag
It is but very low that prepared by the techniques such as pressure significantly improves cost.
Therefore, FRP moulds are made and with the mould system by the rational design of heater in the selection of material and mould
For the sheet material of excellent performance is gone out, a kind of Resin film infusion of FRP moulds is designed, solves problem above.
The content of the invention
The present invention is to overcome the above insufficient, there is provided a kind of Resin film infusion of FRP moulds, is comprised the step of：
The first step, mold material selection, design and preparation：
The determination of material system, the preparation of raw material；The determination of resin mould system and the melting of RFI molding resins film,
Solidification temperature is relevant, pastes upsized frp mould for hand, preferably selects cured resin at room temperature system, research finds cured resin at room temperature
The FRP moulds of system manufacture, its geometrical stability, the capacity of heat transmission on surface and heat endurance substantially meet requirement, can
It is long-term use of at 120 DEG C and indeformable.
Second step, RFI shapings：
Resin film is laid in mold working surface, in its upper strata lay down fibre woven cloth or other fiber preforms, so
Die cavity is encapsulated according to vacuum flexible bag moulding technique afterwards, starts heating system, after resin film melting, under negative pressure of vacuum, melting
Resin is sucked from bottom to top, so as to be impregnated with fiber preform, obtains composite element.
3rd step, heating cloth are pre-buried：
After die surface layer and the solidification of certain thickness enhancement layer, surface of suitably polishing lays heating cloth, and heating cloth is determined
Use can not be folded, folding point resistance is excessive and causes the generation of " focus ", should cover the die area that need to entirely heat, but method
It need not be laid on blue side.
The beneficial effects of the invention are as follows：
A kind of Resin film infusion of FRP moulds of the present invention, described can both avoid temperature too high, and mold materials occur
Large area deformation and burn, can prevent that temperature is too low again, the resin heated time of mold cavity surface is long, and resin film melting is molten
Ooze difficulty.
Embodiment
It is described in detail below with reference to embodiments of the invention.
A kind of Resin film infusion of FRP moulds, is comprised the step of：
The first step, mold material selection, design and preparation：
The determination of material system, the preparation of raw material；The determination of resin mould system and the melting of RFI molding resins film,
Solidification temperature is relevant, pastes upsized frp mould for hand, preferably selects cured resin at room temperature system, research finds cured resin at room temperature
The FRP moulds of system manufacture, its geometrical stability, the capacity of heat transmission on surface and heat endurance substantially meet requirement, can
It is long-term use of at 120 DEG C and indeformable..
Second step, RFI shapings：
Resin film is laid in mold working surface, in its upper strata lay down fibre woven cloth or other fiber preforms, so
Die cavity is encapsulated according to vacuum flexible bag moulding technique afterwards, starts heating system, after resin film melting, under negative pressure of vacuum, melting
Resin is sucked from bottom to top, so as to be impregnated with fiber preform, obtains composite element.
3rd step, heating cloth are pre-buried：
After die surface layer and the solidification of certain thickness enhancement layer, surface of suitably polishing lays heating cloth, and heating cloth is determined
Use can not be folded, folding point resistance is excessive and causes the generation of " focus ", should cover the die area that need to entirely heat, but method
It need not be laid on blue side.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
