Abstract
The utility model relates to carbon fiber composite materials, particularly single direction carbon fiber composite materials which are single driection carbon fiber cloth and single direction carbon fiber plates. The utility model solves the defect that the performance index of the technology of the existing carbon fiber materials is on the low side. The upper layer and the lower layer of a carbon fiber cloth structure are both glue coating layers. The middle of the carbon fiber cloth structure is the carbon fiber cloth. The utility model is characterized in that the carbon fiber cloth of the middle layer is non-woven carbon fiber bundle thread with longitude threads, each bundle thread is form by that 1-3 ten thousand threads are in parallel formed into a group, each diameter phi is (4-7) *10 <-6 > m, the thread surfaces of 5-15 groups are distributed in parallel, the size of the carbon fiber cloth is 200-800g/m< u >, and 8-12 layers of carbon fiber cloth coating glue is pressed to form the carbon fiber plate. The utility model has the characteristics of high strength, high efficiency, shortcut construction, good durability and corrosion resistance, wide application range, easy guarantee of construction quality, thin thickness, light weight, etc. The utility model is very suitable for the reinforcement repair of a reinforced concrete structure.
Description
Technical field: the utility model relates to a kind of carbon fibre composite, and particularly a kind of unidirectional carbon fiber reinforced plastics is unidirectional lamination and unidirectional carbon fiber dimension plate.
Background technology: well-known, carbon cloth has fine physical mechanics property, be commonly used to the reinforcing and repairing of reinforced concrete structure, it is convenient that it has construction, do not have wet trade, do not need large-scale construction equipment, need not the fixed in place facility, the construction period is short, and it has favorable durability and corrosion resistance, the consolidation of concrete structure that can be widely used in all kinds and shape is repaired, and does not change planform and do not influence the structure outward appearance.Yet carbon cloth at present commonly used all adopts through, latitude textile technology, carry out gluing again, technology is numerous and diverse, the cost height, more significant is that carbon fiber wire is because the line footpath is extremely short, warp, latitude carbon fiber move towards crooked, folding volume in fabrication processes, have had a strong impact on the tensile strength of carbon fiber wire, hinder the application prospect of carbon cloth.
Summary of the invention: the purpose of this utility model is to disclose a kind of unidirectional carbon fiber reinforced plastics, this carbon fibre composite has excellent physical and mechanical property, tensile strength is higher than 10～15 times of ordinary steels, and elastic modelling quantity and steel are approaching, and the utmost point is suitable for the reinforcing and repairing of reinforced concrete structure.Solution carbon current fibrous composite performance indications are on the low side and the technical problem of unstable properties.
The utility model is to realize like this, unidirectional carbon fiber reinforced plastics, be unidirectional lamination and unidirectional carbon fiber dimension plate, during for unidirectional lamination, the upper and lower layer of unidirectional carbon fiber reinforced plastics structure is a face glue, the intermediate layer is a carbon cloth, and the intermediate layer carbon cloth is the nonwoven carbon cloth that has only warp, and the every synnema of carbon fiber synnema is by single diameter Ф (4～7) * 10
-6M, one group of 1～30,000 parallel composition of filament, 5～15 beam combination silk plane parallel arrange that described glue-line can be that carbon fiber is covered with width of cloth gluing, also can carbon cloth longitudinal separation gluings, face glue is bi-component, solvent-free, epoxies adhesive.The carbon cloth specification is 200～800g/m
2During for unidirectional carbon fiber dimension plate, this plate is coated with face glue laminated system by 8～12 layers of carbon cloth and forms.
The utlity model has excellent physical and mechanical property, tensile strength is higher than 10～15 times of ordinary steels, elastic modelling quantity and steel are more approaching, the utmost point is suitable for the reinforcing and repairing of reinforced concrete structure, it has favorable durability and corrosion resistance, widely applicable, can be applicable to the xoncrete structure of all kinds and shape, construction quality is easy to guarantee, because carbon fiber nonwoven fabric is soft, even be reinforced the surface is not very smooth, also can guarantee effective stickup of 100%, as finding that pasting the part, rear surface has bubble, can easily throw out air with the method for injector to inject alite paste, realize pasting firmly, also have thin thickness, in light weight, substantially do not increase deadweight and appearance and size behind the reinforcing and repairing.
Description of drawings:
Accompanying drawing is the utility model partial structurtes cutaway views.
Among the figure: the last aspect glue of 1-, 2-subsurface glue, 3-carbon cloth.
The specific embodiment: the utility model is further described below in conjunction with accompanying drawing.
Embodiment 4, and is similar with example 1, is unidirectional carbon fiber dimension plate, and this plate is coated with face glue laminated system by 10 layers of carbon cloth and forms, and face glue is the same solid board face glue of the happy prosperous industrial corporation in Shanghai.Plate limit tensile strength 2816Mpa, stretch modulus 162Gpa, cloth percentage elongation are 1.7%.
