The interlayer toughening carbon fiber-metal layer plywood provided by the invention takes a thermoplastic nylon non-woven fabric with high porosity as an interlayer toughening/isolating layer, a resin matrix in a hot compacting process can smoothly generate penetration and soakage in the toughening/ spacer, the toughening/isolating layer and a basal body resin can not dissolve and generate phase splitting, and the complete non-woven fabric structural style is still kept; further, the nylon non-woven fabric and the basal body resin mutually penetrate so as to form a non-reaction inductive detached three-dimensional net structure, plays the role of the interlayer toughening action, simultaneously obstructs the contact of a carbon fiber strengthening body and a metal plywood, and plays the role of the electrochemistry separate action; and electro-chemical corrosion is caused between the carbon fiber strengthening body and the metal plywood because of potential difference, and the carbon fiber with the excellent mechanical property is used for preparing a fiber -metal layer plywood composite material.
Description
Technical field
The invention belongs to fiber-metal laminate structural composite material manufacturing technology field, relate to a kind of carbon fiber-metal laminate of interlayer toughened.
Background technology
Fiber-metal laminate be a class novel mix the enhancing structural composite material, be referred to as in the world FML(Fiber-Metal Laminate) laminate, its Typical Representative is aluminium alloy-aramid fiber laminated composite materials laminate, be called in the world ARALL(ARAamid-ALuminum Laminate), and aluminium alloy-glass fibre laminated composite materials laminate, be called in the world GLARE(GLAss-Reinforce aluminum).List of references (Vogelesang, L., Development of a New Hybrid Material (ARALL) for AircraftStructure, Ind.Eng.Chem.Prod.Res.Dev., 1983, pp.492-496) with U.S. patent of invention (US.5,039,571, US.5,547,735 and US.5,219,629) all studied the preparation method of FML laminated composite materials laminate in great detail, mechanical property and advantage and potential application.At present, GLARE is applied on the upper body shell structure of A380 aircraft in large area, is a significant innovative point of A380 aircraft material technology.
At present, FML composite both domestic and external all select nonconducting aramid fiber or glass fibre etc. and the carbon fiber of not selecting to have better mechanical property and interface performance as strengthen, toughening material, its reason is that the potential difference of the metal materials such as carbon fiber and aluminium, titanium, steel will form electrochemical corrosion, affect the performance of using for a long time and be on active service of this material, finally cause the structural failure of laminate structures and can't be applied to the manufacturing of aeronautic structure.
Summary of the invention
The objective of the invention is to propose a kind of use high-performance carbon fibre prepreg as the enhancing body, and do not have the carbon fiber-metal laminate of the interlayer toughened of electrochemical corrosion problem.
Technical scheme of the present invention is that described carbon fiber-metal laminate comprises double layer of metal laminate and one deck carbon fiber prepreg at least, and all sandwiching one deck surface density between carbon fiber prepreg and plymetal is 15 ~ 20g/m
2, thickness be the nylon nonwoven fabrics of 30 ~ 40 μ m as toughness reinforcing/separation layer, wherein the nylon molecular weight is 4 ~ 6, fibre diameter is 10 ~ 15 μ m.The paving of laminate sequentially is plymetal-toughness reinforcing/separation layer-carbon fiber prepreg-toughness reinforcing/separation layer-plymetal, the rest may be inferred for the order that stacks of the carbon fiber-metal laminate of other more multi-layered number, after the paving of complete layer plywood, utilize autoclave forming process to solidify the carbon fiber-metal laminate that obtains interlayer toughened.
Fibre reinforcement in the described carbon fiber prepreg is T300 grade carbon fiber or T700 grade carbon fiber or T800 grade carbon fiber.
Matrix resin in the described carbon fiber prepreg is high-toughness epoxy resin.
Described plymetal is aramid aluminiumlaminates or titanium alloy laminate or steel alloy laminate.
Described toughness reinforcing/the used thermal plastic high polymer of separation layer nylon nonwoven fabrics is nylon 6 or nylon 66 or nylon 1010.
Advantage of the present invention is to select the thermoplastic nylon nonwoven with high porosity as interlayer toughened/separation layer, make resin matrix in hot-forming process, infiltration and infiltration can occur in toughness reinforcing/separation layer smoothly, but dissolving and phase-splitting do not occur in toughness reinforcing/separation layer and matrix resin, have still kept complete nonwoven fabric construct form.And then, mutually run through the non-reaction induced three-dimensional net structure that is separated of formation by nylon nonwoven fabrics and matrix resin, play the effect of interlayer toughened, cut off simultaneously carbon fiber and strengthened contacting between body and the plymetal, played the electrochemistry iris action, eliminated carbon fiber and strengthened between body and the plymetal electrochemical corrosion problem that the existence owing to potential difference causes, made the carbon fiber with excellent mechanical property can be used for preparing fiber-metal laminate composite.
