Abstract
The invention provides a quick bonding repair method of an ultraviolet-curing composite material. An ultraviolet-curing resin composition with quick self-propagating curing characteristic, which is used as a base material, is mixed with a fiber reinforcing material to obtain a composite material repair patch. The method comprises the following steps: 1) carrying out surface treatment on a damage region in need of bonding repair; 2) laying a composite material layer on the treated damaged region surface, wherein the thickness and direction of the composite material layer are determined according to the actual demands for repair; and 3) irradiating the composite material layer by an ultraviolet light source to form the composite material repair patch, thereby completing the bonding repair on the damage structure. The composite material repair patch has high designability, can be cured only by single irradiation in the preparation process, and has the advantages of high curing efficiency, favorable tensile strength, high repair efficiency and the like; the curing is not influenced by the number of the fiber layers and the light transmittance of the enhanced phase of the resin-base composite material; and thus, the method is especially suitable for emergency repair operation.
Description
(1) technical field
The present invention relates to photocuring technology, polymer matrix composites technical field, specifically a kind of ultraviolet light polymerization matrix material rapid link repair method.
(2) background technology
Polymer matrix composites have specific tenacity, specific modulus is high, corrosion-resistant, and fatigue resistance is good, and designability waits outstanding advantages by force, is used widely in fields such as aerospace, petrochemical complex and medical materials.Polymer matrix composites can inevitably existing defects or damaged in the manufacturing or use procedure, is meet the normal needs used, need places under repair to its damaged part.The repair method of polymer matrix composites is divided into repair of machine and bonding repairing.Bonding repair method is a kind of high-quality, efficiently structure repair method, gets the nod more and more and apply in the various holes of the building structure such as boats and ships, aircraft and bridge, crackle and corrosion equivalent damage are repaired.
UV-curing technology is the material preparation technology of a kind of green, environmental protection, and this technology being incorporated into polymer matrix composites preparation field is another new developing direction in recent years.Ultraviolet light polymerization reaction curing speed is fast, the required activation energy of reaction is low, is particularly easy to carry out low-temperature curing, is particularly useful for the Spot repair of polymer matrix composites.At present for the research of UV-curing technology, mostly concentrate on fundamental research and the application aspect of this technology in coatings industry, then report is rarely had for the application of this technology in structure repair.Wei Dong etc. have delivered the report being entitled as " a kind of research of aircraft structure quick repairs novel material " on " Packaging Engineering " (the 32nd volume 150-153 page in 2011), take photosensitive resin as matrix, glass fibre is strongthener, be prepared into ultraviolet light polymerization repairing composite material tablet, the quick repairs of aircraft damage structure is studied.Also main forces etc. have delivered the report being entitled as " ultraviolet cured epoxy matrix material and repairing performance study thereof " on " Nanjing Aero-Space University's journal " (the 46th volume 635-645 page in 2014), adopt ultra-violet curing matrix material to repair the laminated wood sample containing artificial defect, result shows that the method has good repairing effect.
But it is limited to be limited by UV-light penetrativity, UV-curing technology is applicable to the glass fiber reinforcements system of printing opacity usually, successively need lay glass fibre, successively repeatedly radiation curing time prepared by repairing composite material tablet, the solidification of disposable rapid deep zone cannot be realized.For containing light tight wild phase system, as the ultraviolet light polymerization of carbon fibre reinforced composite, then have no relevant report.
(3) summary of the invention
Technical assignment of the present invention is for the deficiencies in the prior art, a kind of ultraviolet light polymerization matrix material rapid link repair method is provided, there is the Ultraviolet curable resin composition of quick self-propagating solidification feature for body material, preparing repairing composite material sticking patch after blend fiber strongthener, carrying out rapid link repairing to needing the damage field of bonding repairing.
The technical solution adopted for the present invention to solve the technical problems is:
Ultraviolet light polymerization matrix material rapid link repair method, to have the Ultraviolet curable resin composition of quick self-propagating solidification feature for body material, prepares repairing composite material sticking patch, comprises the steps: after blend fiber strongthener
1) to needing the damage field of bonding repairing to carry out surface treatment, surface treatment mainly comprises solvent cleaning, mechanical grinding or sandblasting, and surface treatment object is the roughness increasing damage field surrounding overlap joint surface, increases bonding strength;
2) lay composite plys on the damage field surface handled well, composite plys is similar to damage field geometrical shape, and composite plys area is greater than damage field area, and compound material laying layer thickness, direction are determined according to the actual needs repaired;
3) adopt ultraviolet source irradiation to lay composite plys, form repairing composite material sticking patch, to complete the bonding repairing to damaged structure.
Described fiber reinforced material comprises glasscloth or carbon cloth.
According to structure and practical situation, described damage field surface treatment both can be one side process, also can be double treatment, and corresponding carries out the bonding repairing of one side or double-sided adhesive repairing.
In order to improve bonding repairing effect further, carry out pressure process to described composite plys, pressuring method adopts vacuum bag pressurization, and vacuum bag must can through UV-light, to cause the ultraviolet light polymerization of composite plys.
The present invention have quick self-propagating solidification feature Ultraviolet curable resin composition, its formula Raw composition and each ingredients weight parts as follows: epoxy resin 90-110 part, cation light initiator 0.1-0.7 part, thermal initiator 0.1-0.5 part.
Described epoxy resin is one or more in glycidyl ether type epoxy resin, glycidyl ester epoxy resin, glycidyl amine epoxy resin, cycloaliphatic epoxy resin, as E44 epoxy resin, E51 epoxy resin, 3,4-epoxycyclohexyl-methyl-3, one or more in 4-epoxycyclohexyl manthanoate, two ((3,4-epoxycyclohexyl) methyl) adipic acid ester, epoxy modified silicone resin.
