Description
Technical Field

Ultraviolet light is used as energy with energy saving, environmental protection and strong penetrability and is widely applied to the curing process of materials, a photoinitiator is added into a material system or a molecular structure is grafted with a modified photosensitive group, a prepolymer or a photosensitive monomer is introduced under the induction of ultraviolet light to change from a ground state to an excited state, and then complexes for electron transfer are formed, and the complexes are continuously subjected to crosslinking reaction to form a three-dimensional network polymer. The mechanism of thermal curing is also similar, that is, the photoinitiator is changed into a thermosensitive initiator, and the initiator is cracked at a certain temperature to generate free radicals to initiate polymerization reaction. Both photo-curing and thermosetting techniques have been widely studied in the field of composite material repair, and especially thermosetting techniques have become the main means for curing composite materials.
However, the hot-repair instrument mainly used for repairing the composite material at present is not suitable for curing a complex structure, the curing temperature of the hot air blower is not uniform, and the temperature cannot reach higher temperature, so that the repair time of the composite material can often reach several hours, and the efficiency of repairing the structure is affected.
In order to improve the curing speed of the composite material, many researchers turn their attention to the field of light curing, and the glass fiber resin-based composite material can realize laminate curing with a certain thickness due to the better light transmittance of the fiber. For the carbon fiber resin matrix composite material, because the carbon fiber is an opaque black medium, ultraviolet light is difficult to penetrate through and difficult to penetrate into the material for curing, so that curing is uneven, and general photocuring resin has low heat resistance and poor mechanical property, and has less engineering application in the actual aircraft repair.

Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the invention is further explained in the following with the accompanying drawings and the embodiments.
The invention relates to a dual light source photo-thermal curing method suitable for emergency repair of an outfield complex structure, which starts from three aspects of curing materials, curing equipment and a curing process and comprises the following specific steps:
step one, determining the proportion of a photo-thermal initiator:
for the airplane responsible for structural repair, the prepreg is made of resin and fiber fabric, and then the corresponding patch shape and thickness are cut according to the repair part, so that the formula of a resin system needs to be developed. Although repair has certain requirements on the curing speed, if the curing speed is too high, the problems of air bubbles being unable to be discharged, large porosity of the patch and the adhesive layer, and the like are caused, so that the repair speed is not as high as possible. The adhesive resin adopts an epoxy system including but not limited to CEP, T26, E54 and other brands.
Firstly, the curing degree of the resin respectively containing the photo-thermal initiator and the photo-thermal initiator is measured at the same time, taking the curing time of 20min as an example, wherein the relationship between the content of the curing agent in the photo-initiation system and the curing degree is as follows:
the resin curing degree of the photoinitiator with the content of less than 2 percent reaches more than 70 percent when the photoinitiator is irradiated by power of 150W for 20 Min;
the resin curing degree of the photoinitiator with the content of less than 2 percent reaches more than 85 percent when the photoinitiator is irradiated by 20Min with 200W power;
the resin curing degree of the photoinitiator with the content of 3% -4% reaches more than 85% when the photoinitiator is irradiated by power of 150W for 20 Min;
the resin curing degree of the photoinitiator with the content of 3% -4% reaches more than 96% when the photoinitiator is irradiated by power of 200W and 20 Min.
The relationship between the content of the thermal initiator curing agent and the curing degree is as follows:
the resin curing degree of the thermal initiator with the content of about 0.1 percent reaches more than 30 percent when the thermal initiator irradiates 20Min at the power of 800W;
the resin curing degree of the thermal initiator with the content of about 0.5 percent reaches more than 50 percent when the thermal initiator irradiates 20Min at the power of 800W;
the resin curing degree of the thermal initiator with the content of about 1 percent reaches more than 80 percent when the thermal initiator irradiates 20Min at the power of 800W;
the resin curing degree of the thermal initiator with the content of about 0.5 percent reaches more than 65 percent when the thermal initiator irradiates 20Min with 1000W power;
the resin curing degree of the thermal initiator with the content of about 1 percent reaches more than 95 percent when the thermal initiator is irradiated by 20Min at the power of 1000W.
Considering that in the photo-thermal curing system, the heat generated by the photo-curing reaction further stimulates the thermal initiator to decompose, and the heat generated by the thermal curing reaction further accelerates the photo-curing reaction, the photo-initiator content and the thermal initiator content are not too high in order to control the speed of the double reaction and the crosslinking density, so that the photo-initiator content of 2% and the thermal initiator content of 0.5% are selected.
