Abstract
The invention provides a three-dimensional fabric reinforced phenolic resin composite material and a preparation method thereofghAn open mode is adopted. The invention adopts a special curing system and a runner design, overcomes the difficulties of air bubble inclusion and high porosity in the phenolic resin RTM process, can effectively improve the RTM forming efficiency of the ablation-resistant component with large thickness and the internal quality of a workpiece, and solves the key problem of the forming process.
Description
Technical Field
The invention relates to a three-dimensional fabric reinforced phenolic resin composite material and a preparation method thereof, in particular to a three-dimensional fabric reinforced phenolic resin composite material with the thickness of more than 30mm and a preparation method thereof, belonging to the technical field of composite material preparation.
Background
The phenolic resin is used as a thermosetting resin material with high crosslinking density, and is gradually carbonized at high temperature to form a carbonized layer, and the carbonized layer has high strength and high heat resistance and is suitable for extremely severe environments such as high temperature, high pressure, high-speed airflow scouring and the like, so that the ablation-resistant phenolic composite material is widely applied to an outer-layer heat-proof structure of a high-speed aircraft or spacecraft.
In order to ensure the surface protection effect of the aircraft in the ultra-high speed flight state, the thickness of the external ablation heat-protection layer is larger, and particularly for the tip parts of the aircraft, such as airfoil leading edges, air inlet edges and the like, the thickness of the heat-protection layer is generally larger than 30 mm. For the heat-proof structure of the large-thickness area, the interlayer weak area of the composite material can be effectively eliminated by adopting the three-dimensional woven fabric, and the uniform ablation resistance and stripping resistance effects are achieved.
For the large-thickness composite material reinforced by the three-dimensional woven fabric, the RTM process is the most effective forming technology, and the process requires that no or few micromolecules are generated in the curing process of the resin so as to reduce the defects of the product and improve the performance. However, the curing reaction of the phenolic resin is a polycondensation reaction, small molecules are released in the reaction, the phenolic resin suitable for the RTM process also contains part of solvent, volatile matter of the small molecules is also formed in the heating process, and the pore defect is easily formed in the product, and the application of the phenolic RTM technology is limited by the defects.
In addition, as the RTM process is a process of injecting liquid resin into dry fibers, excess gas in the mold cavity is exhausted by filling the pores between the fibers with the flow of the resin, the general glue flow channel is designed in the length or width direction of the article to form a long-range flow of the resin, so as to achieve the purpose of sufficiently eliminating the mixed bubbles. However, for the large-thickness composite material reinforced by the three-dimensional woven fabric, a large number of weaving nodes of the fibers exist, the time for resin to penetrate the nodes is far longer than the time for resin to flow among fiber bundles, so that the resin flows slowly in the RTM process of the woven fabric type component, and in the preparation of a large-scale component, the resin flowing and mold filling efficiency is too low to exceed the service life of RTM resin, so that the component is possibly scrapped.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a large-thickness three-dimensional fabric reinforced phenolic resin composite material with stability, high efficiency and strong operability and a preparation method thereof, can effectively improve RTM (resin transfer molding) forming efficiency and internal quality of a workpiece of a large-thickness ablation-resistant component, and solves the problem of forming process.
The technical solution of the invention is as follows: a three-dimensional fabric reinforced phenolic resin composite material is prepared by an RTM process, and is subjected to stage heat preservation and exhaust in the curing process at the resin curing temperature TghAn open mode is adopted;
the stage heat preservation and the exhaust are carried out at the temperature T in the quick rising period of the viscosity of the phenolic resinnsAnd TghBetween (not including the temperature T)gh) At least 3 heat preservation exhaust steps are arranged, and the temperature of the first heat preservation exhaust step is TnsThe temperature difference between adjacent heat-preservation exhaust steps is not lower than 10 ℃, the heat preservation time of each heat-preservation exhaust step is not lower than 1 hour, the glue outlet is opened to exhaust after each heat preservation, and the exhaust time is not more than 5 seconds;

According to the rheological characteristics of the phenolic resin, the invention adopts stage heat preservation and exhaust in the curing process and an open type post-treatment method, so that the internal pores of the product are reduced, and the qualification rate is improved.
The concrete implementation method is that measures of stage heat preservation and air exhaust are adopted in the rapid rising period of the viscosity of the phenolic resin and the curing process so as to release the micromolecules in the mold cavity, and meanwhile, a glue outlet is opened in the curing and shaping and post-processing stages of the resin so that the micromolecules generated in the curing process can be fully overflowed.
The glue flowing channel of the RTM process is designed along the thickness direction of the three-dimensional woven fabric.
According to the cross section appearance characteristics of the large-thickness ablation-resistant component, the glue injection flow channel of RTM resin is shortened to short-distance flow by designing the glue flow channel along the thickness direction of the three-dimensional woven fabric, so that the resin injection difficulty is remarkably reduced, and the efficiency is improved.
The concrete realization method of the glue flowing channel along the thickness direction of the fabric is that a flow guide net or linear/latticed glue injection port is adopted on one side of a non-working surface with large thickness of the woven fabric to form a large-area glue injection form, and glue outlets which are uniformly distributed are designed on the other side of the thickness of the fabric, so that the main body flowing direction of the resin is the thickness direction of the fabric.
