Abstract
The invention relates to a connection structure of a composite material superstructure and a steel hull. The connection structure comprises a filling core material, a steel plate, a bonding layer and a composite material coating, wherein the bonding layer and the composite material coating are coated on the end surfaces of the filling core material and the steel plate from inside to outside in sequence. One end of the steel plate extends into the filling core material, and the other end of the steel plate extends out of the bonding layer and the composite material coating to be connected with a steel deck. The bonding layer and the composite material coating extend upwards to the end surface of a matrix core material covering the composite material superstructure. The connection structure is reasonable in structure, high in connection strength and convenient to manufacture. The connection structure and the matrix structure of the composite material superstructure are formed integrally, the problem of low strength caused by the secondary bonding process required by connection of composite materials is avoided, consistency and reliability of connection of structures are greatly improved, the problem that thermosetting resin matrix composite materials frequently used for making ships cannot be welded with the steel plate directly is solved, the manufacture process is simplified, and construction of real ships is facilitated.
Description
Technical field
The present invention relates to boats and ships composite material application, relate in particular to a kind of core filled composite material superstructure of boats and ships and connection structure of steel hull of being applied to.
Background technology
The superstructure material of steel boats and ships generally adopts steel or aluminium at present, boats and ships are under the effect of periodicity wave power, the hull superstructure easily produces endurance failure, especially in the rear and front end of superstructure and the junction of main body, thereby bring out lasting endurance crack owing to being subject to serious local reverse load, thereby shorten the useful service life of boats and ships.
In order to improve the connection Fatigue Life Problems of steel or aluminium superstructure, adopt light-duty core filled composite material structure design ship superstructure to become the focus of research and application.Adopt the superstructure of core filled composite material structure building on traditional steel boats and ships, the precedent of external existing application, the superstructure of typical as novel as United States Navy destroyer leader " DDG-1000 ", Republic of France Navy " La Fayette " level destroyer escort etc. has all adopted advanced core filled composite material structure.Utilize core filled composite material and the unmatched characteristic of steel bomb modulus (modulus of elasticity of glass fibre reinforced composion peculiar to vessel only only has 10%～15% left and right of steel bomb modulus), the stress that can effectively alleviate superstructure and deck in ship structure junction is concentrated, and improves and connects strength at repeated alternation.Utilize core filled composite material strength-to-density ratio, stiffness-to-density ratio than steel, the much bigger advantage of aluminium, the energy actv. alleviates the weight of superstructure structure, reduces the boats and ships height of gravitational center, improves Stability of Ship and rapidity simultaneously.Utilize the designability of fiber reinforced composite in the core filled composite material structure and the sound insulation characteristics of core, make the core filled composite material superstructure also have the performance that sound insulation, the traditional material such as stealthy are difficult to obtain concurrently, therefore using the core filled composite material structure is a developing direction of following ship superstructure design.Can design for these reasons a kind of novel compound hull, i.e. superstructure is core filled composite material, and main body is still the conventional steel plate.But core filled composite material and steel plate material are two kinds of complete materials of different nature, and there is certain technical risk in the junction of the two, in the urgent need to designing and manufacture the connection structure that a kind of Joint strenght is high, reliability is strong, easily manufactured.
Summary of the invention
The applicant can't direct coupled problem for above-mentioned existing core filled composite material and steel plate material hull, be studied improvement, a kind of rational in infrastructure, easily manufactured composite material superstructure and the connection structure of steel hull are provided, have advantages of that good reliability, Joint strenght are high, easily manufactured.
The technical solution adopted in the present invention is as follows:
The connection structure of composite material superstructure and steel hull, comprise and fill core, steel plate, and according to sequentially covering from the inside to the outside tack coat and the composite material epidermis of filling core, steel plate end face; One end of described steel plate stretches into the inside of described filling core, and the other end stretches out described tack coat and composite material epidermis and is connected with steel deck; Described tack coat and composite material epidermis extend upwardly to the end face of mulching composite superstructure parent core.
Its further technical scheme is:
Described composite material epidermis adopts fiber-reinforced resin matrix compound material, fibers form in described fiber-reinforced resin matrix compound material can adopt any one of flat fabric, unidirectional cloth, stitch-bonded felt and various three-dimensional weave or its combination, and can add chopped mat or surperficial felt in above-mentioned fibers form;
The fiber that described fiber-reinforced resin matrix compound material is the preimpregnation matrix resin or do not soak any one in the fiber of matrix resin, above-mentioned fiber is selected from any one in glass fibre, carbon fiber, continuous basalt fiber, aramid fiber or above four kinds of combinations;
Described filling core can be any one in cork wood core, polyurethane (PU) foam, polyvinylchloride (PVC) foam, acrylonitrile-styrene (SAN) foam, polyetherimide (PEI), polyethylene terephthalate (PET) and Polymethacrylimide (PMI) foam core material material;
The material of described tack coat 4 is any one in unsaturated polyester resin, epoxy resin, vinylite, phenol resin;
The matrix resin of described fiber-reinforced resin matrix compound material is selected from any one in unsaturated polyester resin, epoxy resin, vinylite, phenol resin;
Described preimpregnation matrix resin is selected from any one in unsaturated polyester resin, epoxy resin, vinylite, phenol resin.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, Joint strenght is high, easily manufactured, the present invention and composite material superstructure precursor structure are one-body molded, usually need the low problem of Joint strenght that adopts the secondary bonding process to bring while avoiding composite material to connect, greatly improved conformability and reliability that each structure connects; Steel plate is incorporated in the design of connection structure, make connection structure can be directly and steel deck welded, overcoming boats and ships thermosetting resin based composites commonly used can't be directly and the problem of Plate Welding, has simplified manufacturing process, is conducive to real ship construction; The present invention stretches into and fills core inside by the end by steel plate, avoided carrying out in Ruo sectional position, bonding pad the material transition of core and steel plate, causing thus the stress of this position concentrates and then the weakening Joint strenght, fill core simultaneously and adopt than parent core shearing strength value and the higher material of modulus, greatly improved the bending property of structure of the present invention.
