Description

A kind of large-sized composite material casing forming method
Technical field
The present invention relates to a kind of casing forming method, particularly relate to a kind of large-sized composite material casing molding side Method.
Background technology
Canister launch technology can be effectively improved the storage reliability of missile weapon system because of it, have whole day Wait the advantage such as adaptation ability and battlefield quick-reaction capability, military by current various continental rises and carrier-borne sophisticated missile Device system uses.The core of canister launch technology and it is crucial that firing box, the Main Trends of The Development in its future it One is exactly the miniaturization of firing box, lightweight.Since the seventies, fibrous composite is with its specific strength Height, specific modulus height, the designability of mechanical property, damping shock absorption, endurance, ageing-resistant, moulding process The series of advantages such as simple, obtains in fields such as Aero-Space and is widely applied.
Casing as storing firing box key component, carry contain guided missile, install finder and Primary load bearing effect, belongs to large scale closed cross-section member.Fibre reinforced composites are used to manufacture firing box casing, The problems such as weight big, welding deformation, easy-to-rust that metal structure casing exists can be solved well, And the lowest production cost, open wide prospect for application on storing firing box.
Firing box mostly is the structures such as tetragon, hexagon, octagon, and the polygon goods length of side is more than 300mm, Length 2000mm~15000mm, thickness is more than 2mm.Reinforcing material can select glass fibre, carbon fiber, height Strong fiber, basalt fibre;Resin material can select epoxy resin, vinylite, unsaturated-resin, The synthetic resin such as phenolic resin, polyimide resin.
The main moulding process of composite material launching box has wet method hands paste, prepreg autoclave bag pressure, fiber to be wound around Etc. several technological formings.Wet method hand pasting forming strength of materials performance rate is the highest, anthropic factor is relatively big, causes criticizing Production. art reliability is poor;Prepreg autoclave bag presses technique raw and auxiliary material, equipment investment higher, and cost is relatively Greatly, especially large scale goods;Fiber winding forming needs proprietary forming frock just can realize polygon goods Molding, the realisation complexity of technique.Vacuum assisted resin transfer molding technique (VARTM/SCRIMP) is applicable to Prescription height, small lot and larger-size goods.The composite processed in this way, fiber contains Amount height, Mechanical Properties of Products is excellent, and product size is unrestricted, is especially suitable for making massive article. It is compared with traditional autoclave forming process, has die cost low, resin cold curing and hardly The feature that restricted product size etc. are prominent.Development and the property of relevant raw and auxiliary material along with SCRIMP technique Can improve, make SCRIMP technique have obvious advantage in terms of polygon product molding.
