Description
Technical field
The present invention relates to a kind of high modulus carbon fiber sheet material and manufacture method thereof.
Background technology
Composite is the material with powerful vitality of answering development of modern scientific technology and emerging, and it is by the new material of method through being manually compounded to form of two or more heterogeneous, special-shaped, different in nature material physics and chemistry.Generally be made up of matrix constituent element and reinforcement or function constituent element.Composite can through design, namely by raw-material selection, the guarantee etc. of each component distribution design and process conditions, makes stock blend material advantages complementary, thus manifests outstanding comprehensive.
Composite can be divided into structural composite material and the large class of functional composite material two by purposes difference, and the situation that structure composite and functional composite material are laid equal stress on will appear in future, and functional composite material has more the advantage of competing with other functional material.
This functional composite material:
1, it utilizes the physics of composite, chemistry or biological function as main application, such as we are by the electric property of composite, magnetic performance, optical property, thermal property, radioactivity performance, biology performance and mechanical property, can Design and manufacture or have multiple can composite.
2, it is the heterogeneous material by matrix and functional structure.Matrix mainly plays cementation, also plays function under certain conditions, and the functional of composite is contributed primarily of functive, and the functive adding different qualities can obtain the different functional composite material of characteristic.
Functional composite material is a large classification of the composite of cash, people are not strange to functional composite material, the god five be with historically new significance is a kind of typical functional composite material to the solar heat protection of refreshing ten Manned reentry capsule, heat-barrier material, people absorbing material on the stealthy airship be familiar with, automobile-used high performance brake sheet friction resistance composite material, the ballistic composite etc. of the bullet-proof vest of the protection level of lightweight is all fresh functional composite material.
2.1 functional composite materials are made up of functive and matrix, and except the property of functive and matrix has impact on content with in conjunction with situation to its performance, the performance of functive itself more has a direct impact composite, particularly resin composite materials.
The reliability of 2.2 raising composites, must from the quality control of group element material forming compound composite.
The synchronism of material-structure, technique:
1, functional composite material often while forming materials product structure also shaping, each step in technical process all can affect the functional performance of composite.
2. will improve the reliability of composite, composite material process planning quality of controlling well is vital.
Summary of the invention
Object of the present invention is exactly to solve the problem, and provides a kind of high modulus carbon fiber sheet material and manufacture method thereof.
To achieve these goals, the present invention adopts following technical scheme:

The present invention adheres to relative to the amount of the preferred 0.1-2 % by weight of carbon fiber, and thickness is 20-200 dust.
Epoxy resin, generally refer to the macromolecular compound at least containing two epoxy radicals, epoxy resin thermosetting resin, it can carry out with curing agent the solidfied material that cross-linking reaction generates different performance, and with extensive stock form (as reinforced plastics, coating, moulding material, adhesive material, sealant etc.) supply market.There is in epoxy molecule structure the aliphatic hydroxyl of pole, ehter bond and the epoxy radicals of ripple of very living, therefore to polar material, there is efficient bonding force, and there is the advantages such as good chemical proofing, electrical insulating property and shrinkage factor be tricky.Therefore, in the base-material of synthetic adhesive, no matter be in performance and kind, or output and purposes aspect, epoxy resin all occupies very important status.
The advantage of epoxy resin: the large molecular end of epoxy resin is epoxy radicals, has hydroxyl and ehter bond in the middle of chain, and also can continue in the curing process to produce hydroxyl and ehter bond, and containing phenyl ring or heterocycle in structure, these structures shape T epoxy resin have the following advantage.Four cohesive forces are large, and strong fat of gluing can produce gravitation with adjacent interfaces.Epoxy radicals can react with the free key in medium inner feelings face, becomes chemical bond, so epoxy resin is firm strong especially with joint efforts.After epoxy resin cure, cohesive force is large.Epoxy radicals can also be bent surface with gold under certain condition and be formed chemical bonds simultaneously, because very high gluing intensity is revealed in inner feelings, shear strength can reach 65Pa, peel strength is 5KN/m, it is to most of material, as timber, metal, glass, plastics, rubber, leather, pottery, fiber etc. have good cement properties.
Traditional sheet metal lighter in weight, mechanical performance is compared with carbon fiber composite board, and the latter's advantage is larger, and along with the development of society, the application of carbon fiber sheet is quite extensive, is industry, the requisite quality material of space material.
The present invention is polymer matrix composite, and performance has one's own knack, and its moulding process has its feature compared with other material processing technique.
The production process of namely composite in the process of composite product, in composite preparation, the bonding interface of matrix resin is the key factor occurred that affects the mechanical properties.
The present invention uses same with thermosetting compound material forming method.
The present invention has scientifically formulated technological specification, rationally determines the technological parameters such as temperature, pressure, temperature retention time, makes the goods after solidification have good performance.
The present invention uses resin, transmission, die pressing to make.
The axial stereo fabric of carbon fiber and carbon fiber bidirectional fabric epoxy resin make adhesive, in the airtight die cavity of lay, with heating, pressurizeing resin liquid are injected die cavity, transform fabric, then cure and demold goods.
Manufacturing dimension of the present invention is accurate, and can be made into various middle-size and small-size container and various instrument, the dial plate, shell etc. of instrument, also can make small boat housing components.
