Abstract
The invention relates to the field of building materials, in particular to a processing method for a plate containing a carbon fiber. An epoxy resin layer is adopted on the outer side of a carbon fiber layer, and due to the fact that the strong mechanics characteristic and excellent endurance performance cannot be brought into full play merely by means of carbon fiber pieces, the goal of reinforcement can be achieved only by enabling the carbon fiber pieces to be adhered to the surface of a reinforced concrete structure through epoxy resin and tightly combined with the surface of the reinforced concrete structure to form a whole so as to work jointly. The carbon fiber plate is suitable for a prestress reinforcing mode, the high-strength effect of the carbon fiber can be brought into full play, the plate is convenient to construct, construction quality is guaranteed easily, fiber straightness is maintained easily, and the carbon fiber can play a role easily. The plate has good durability and corrosion resistance, is resistant to acid, alkali, salt and corrosion of the atmospheric environment, and can be used for the maintenance and reinforcing process of a concrete structure in narrow fields under severe conditions.
Description
Technical field
The present invention relates to building material field, concretely, relate to a kind of method for processing sheet material that contains carbon fiber.
Background technology
Carbon fiber is a kind of fibrous carbon material.It is a kind of strength ratio steel large, density ratio aluminium little, than stainless steel also corrosion-resistant, than heat resisting steel also high temperature resistant, can conduct electricity as copper again, have the new material of electricity, calorifics and the mechanical property of many preciousnesses.The aircraft that the composite made from carbon fiber and plastics is done is not only light and handy, and consumption of power is few, and thrust is large, and noise is little; With the disk of carbon fiber electronic computer processed, can improve storage capacity and the arithmetic speed of computer; Make the space vehicles such as satellite and rocket with carbon fibre reinforced plastic, mechanical strength is high, and quality is little, can save a large amount of fuel.Carbon fibre material is compared with other reinforcement materials: tensile strength is about 10 times of steel; Tensile modulus of elasticity is higher than steel; Fatigue strength is higher than high tensile steel wire; Weight is about 1/5th of steel.
The characteristics of carbon fibre composite are exactly that light weight is high-strength, but processing difficulties, process of preparing is varied, and the carbon fiber product quality that obtains with the carbon fiber of different process and the different trades mark differs greatly.Carbon fiber is fibrous material with carbon element, and in its chemical composition, phosphorus content is more than 90%.Because the simple substance of carbon at high temperature can not melt (distilling) more than 3800K, and do not dissolve in various solvents, so so far can't be with the simple substance of carbon carbon fiber processed.At present, people can't directly be pumped into carbon fiber with carbon or graphite, can only adopt the organic fiber (as nylon yarn, acrylics filament, artificial silk etc.) of some carbon containings to do raw material, organic fiber is combined with plastic resin, be placed in the atmosphere of rare gas, the heat-flash charing forms under certain pressure intensity.
Summary of the invention
For above-mentioned technical problem, in view of the defective of prior art, the purpose of this invention is to provide a kind of method for processing sheet material that contains carbon fiber.
Technical scheme to be solved by this invention is as follows:
A kind of method for processing sheet material that contains carbon fiber is made of basalis, carbon fiber layer, epoxy resin layer and reinforcing watertight composition; Select according to demand the wooden boards of thickness range between 300mm-1200mm as basalis; At the bonding carbon fiber layer in the both sides of wooden boards, carbon fiber layer has been mingled with the glass fabric of percentage composition at 5%-50% according to demand, and the percentage composition of carbon fiber is no less than 50%; Epoxy resin layer is adopted in the outside at carbon fiber layer, sticks on the surface of carbon fiber layer with compression molding; Outermost at epoxy resin layer has adopted the reinforcing watertight composition.
Carbon fiber in described carbon fiber layer is made through carbonization by polyacrylonitrile fibre, pitch fibers, viscose or phenolic fibre.
The invention has the advantages that: epoxy resin layer has been adopted in the outside at carbon fiber layer, can not give full play to its powerful mechanical characteristic and superior endurance quality because only rely on carbon fiber sheet itself, only have by epoxy resin carbon fiber sheet is adhered to the reinforced concrete structure surface and closely is combined together to form with it whole common work, just can reach the purpose of reinforcement.Carbon fiber sheet more is applicable to adopt the prestressed reinforcement mode, more can give full play to the effect of carbon fiber high-strength degree; Easy construction, construction quality are easy to guarantee; Be easy to keep fiber straight, more be conducive to carbon fiber and play a role; Have good durability and corrosion resistance, the corrosion of acid and alkali resistance, salt and atmospheric environment, the condition that can be used for is harsh, in the maintenance of the xoncrete structure of narrow space, reinforcing process.
The specific embodiment
A kind of method for processing sheet material that contains carbon fiber is made of basalis, carbon fiber layer, epoxy resin layer and reinforcing watertight composition; Select according to demand the wooden boards of thickness range between 300mm-1200mm as basalis; At the bonding carbon fiber layer in the both sides of wooden boards, carbon fiber layer has been mingled with the glass fabric of percentage composition at 5%-50% according to demand, and the percentage composition of carbon fiber is no less than 50%; Epoxy resin layer is adopted in the outside at carbon fiber layer, sticks on the surface of carbon fiber layer with compression molding; Outermost at epoxy resin layer has adopted the reinforcing watertight composition.
Carbon fiber in described carbon fiber layer is made through carbonization by polyacrylonitrile fibre, pitch fibers, viscose or phenolic fibre.
The invention has the advantages that: epoxy resin layer has been adopted in the outside at carbon fiber layer, can not give full play to its powerful mechanical characteristic and superior endurance quality because only rely on carbon fiber sheet itself, only have by epoxy resin carbon fiber sheet is adhered to the reinforced concrete structure surface and closely is combined together to form with it whole common work, just can reach the purpose of reinforcement.Carbon fiber sheet more is applicable to adopt the prestressed reinforcement mode, more can give full play to the effect of carbon fiber high-strength degree; Easy construction, construction quality are easy to guarantee; Be easy to keep fiber straight, more be conducive to carbon fiber and play a role; Have good durability and corrosion resistance, the corrosion of acid and alkali resistance, salt and atmospheric environment, the condition that can be used for is harsh, in the maintenance of the xoncrete structure of narrow space, reinforcing process.
