Description
Technical field
The present invention relates to high modulus carbon fiber bearing member processing method.
Background technology
In the process of human sciences's technical development, the appearance of new material and new technology always can promote improving of science and technology.Such as, 1960's S Design teacher courageously have employed the new technology that fiber impregnation thermoset ting resin composite is wound around motor body when developing Polaris (Poloris) A3 guided missile, to replace the cutting forming technique of steel alloy, this parts loss of weight is made to reach 45%, scope increases to 4000km by 1600km, increases journey 150%.Whole manufacturing process is also simplified, and make the production cycle shorten 1/3, cost is reduced to 1/10 of original titanium alloy.Its success has shaken guided missile circle and material circle, this adopts composite as main bearing capacity structural material first, thus be put into Aerospace Engineering history, the invention success of winding process is also loaded with composite development history in modern age as the milestone of new material, new technology.
Composite uses suitable method by two or more combination of materials of different nature a kind of new material formed together.This material can overcome the shortcoming of homogenous material, improves the performance of homogenous material, and by the mutual synergy of each composition material in performance, can obtain the superior combination property that homogenous material is incomparable.Such as: typical light weight characteristic, remarkable specific strength, specific modulus, unique resistance to ablation and disguise, good chemical/physical stability (acidproof, alkaline-resisting, fire-retardant etc.), damping, antimagnetic, the designability of material property, the flexibility of preparation and workability etc.So composite is widely used in the high-tech area such as Aero-Space, weapons, and expand to civilian industry gradually.But the development of composite also must depend on machinery manufacturing industry provides advanced process equipment for it.Just current, traditional plant equipment can not meet the demand for development of new material, new technology, therefore develops the needs that the advanced person of applicable composite production, high-performance numerical control Cloth Tape Winding Machine and the Precise Tension Control System of Digital as its indispensable servicing unit are scientific technological advances.
Carbon fiber development and application can trace back to the carbon filament of 1850, after this research application stays cool always, to the development of the fifties in last century along with industrial technology and the requirement of war industry, the research and production of carbon fiber, in succession solve the selection of precursor and the industrial manufacture process of high temperature cabonization, carbon fiber is applied and just enters into a new stage.Twentieth century sixties, be that the reinforced concrete structure solving offshore area and weather cold district suffers salt to lose the problem of harm, U.S.A produces a kind of GFRP reinforced-concrete.In addition, at some sea walls, industrial premises roof boarding, be in the concrete floor etc. of erosion environment condition, CFRP product is more and more widely used.Add short carbon fiber and can improve concrete performance well while on stirring coagulation. according to its planform, electrothermal prestressing, sheet material method for strengthening even all can well be applied in shock insulation, shock absorption method in vitro.The many institution of higher learning of recent year, scientific research department and Ge great designing institute all participate in the application and research to carbon fiber, current country does not also promulgate formal design and job specfication. in the research project that the Ministry of Construction determines, include the problem such as " fibre reinforced composites (FRP) are studied with repairing for the reinforcing of Urban Bridge ", " carbon fibre material reinforced concrete structure new technology ", the application study of carbon fiber has obtained the attention of enclosing house.
Carbon fiber is also known as reinforced composite CFRP (CarbonFiberReinforcedPolymer), it is manufactured chemical's fiber that is higher by phosphorus content, not melting in heat treatment process, make through techniques such as thermally-stabilised oxidation processes, carbonization treatment and graphitizations, as its phosphorus content more than 90%.According to the difference of raw material, manufacture method, carbon fiber is divided into PAN (polyacrylonitrile) base carbon fibre and the large class of asphalt base carbon fiber two.Carbon fiber has the characteristic of general carbon materials, as high temperature resistant, wear-resisting, conduction, heat conduction and corrosion-resistant etc., but with ' as carbon materials unlike, its profile has significant each diversity, along fiber axis to showing very high intensity.Carbon fiber proportion is little simultaneously, has very high specific strength, compared with steel, and weight saving 3/4, and intensity improves 2 times.The composite being combined by carbon fiber and epoxy resin and made, its specific strength, specific modulus overall target are the highest in existing structure profit material.Have the field of strict demand in intensity, rigidity, weight, fatigue properties etc., requiring the occasion that high temperature, chemical stability are high, carbon fiber composite is sentenced and is all had much advantage.Due to carbon fibre material, to delete acid, wool grass saline and alkaline, ageing-resistant, high temperature resistant, low temperature resistant etc. again, has good protective effect after carbon fibre material is pasted onto surface to original structure.
At national defence and aviation field for the U.S. of carbon fiber greatest requirements state, U.S. solid from president to minister, arrive military circles leader again, all based on the effect in new technology, technological progress, adaptive capacity, conversion techniques innovation concept etc. war, and modern weapons equipment development miniaturization, lighting, high strength, the long-life, mobility, stability, all from the application of not outer carbon fiber.Carbon fiber has very important impact in national defense industry.In Ministry of National Defence's military products, air force is the main users of carbon fiber, and according to 2002 to 2005 total system juice, the demand of air force to carbon fiber accounts for Ministry of National Defence to total carbon fiber requirements 54.8%; Naval then accounts for 29.1%; Ground force accounts for 13.6%; Many arm of the services account for 2.5%.This, based on the level that is in a leading position in current arms race, must improve the flexibility of military secret, disguise, high speed, energy saving, and carbon fibre material is best selection, and therefore novel military secret will definitely continue to improve CFRP demand.
At aviation field, the particularly American-European aircraft manufacturing company of current World Airways circle all very pays close attention to closely without amount airplane crash event frequent over year, especially the accident event of China Airlines Limited of Taiwan Province Boeing E machine, distinguish caused by the fatigue aging owing to belonging to material more than aircraft, European airbus released the airliner of new generation that can hold 500 to 800 people by taking the lead in 2006 for this reason, the carbon fiber consumption of every airplane is up to 40 II, L, nearly 10 times are exceeded than current aircraft, not only for aircraft once with secondary structure material, and by fourth: on joist and escalator, to guarantee the security of aircraft, reliability and energy-conservation, this is because carbon fibre composite has the excellent anti-aging life-span, impact resistance, anti-flammability, light weight and shock damping characteristic.
A kind of new trend of civil engineering field Strengthening Technology has been become in the general application of industrial field carbon fiber in civil construction such as building, the energy.Because the transport of carbon fiber Dan Shu is convenient, easy construction, and to advantages such as the adaptability of planform are better, therefore reasonable employment carbon fiber Dan Shu is affixed on coagulation scholar surface, makes the reinforcing bar cooperative bearing in it and original structure, just to improve the bearing capacity of structure.In the energy and energy storage, be another large purposes place of carbon fiber equally as wind power generation blade wheel, battery and the aspect such as oil-gas mining, pressure vessel.Such as, and petroleum pipeline and vapour automotive natural gas bottle be wound up as rich making with PAN base carbon fibre or its in glass fiber hybrid.The metropolitan buses such as existing Tokyo have employed CFRP bottle all.
From material property, CFRP has following characteristics:
1) intensity is high.High-strength carbon fiber as suitable with steel in elastic modelling quantity, its tensile strength is than large 10 times of steel.
(2) elastic modelling quantity is high.Large 1.8 ~ 2.6 times of modular ratio reinforcing bar as high resiliency model carbon fiber.
(3) quality is light.Its density is generally 1/5 of steel.
(4) resistance to corrosion is strong.Alkali fiber does not produce electrochemical corrosion and intensity reduces very little under the material effects such as chlorion, carbonic acid and caustic soda.
(5) fatigue performance is good.The fatigue strength of common metal is 40 letters 50% of its hot strength, and the fatigue strength of CFRP is 70% ~ 80% of its hot strength.
(6) without electromagnetic induction.As aramid fiber and glass fibre resistance are large, can be used on the place of insulating requirements; Carbon fiber is nonmagnetic, can be used on the occasion of magnetic resonance equipment, with exclusive PCR.
(7) damping property is good.The CFRP natural frequency of vibration is high, can avoid early stage resonance, and its internal resistance simultaneously (internal friction) is also very large, once excited vibration, can decay rapidly.
