Abstract
The invention relates to a process for curing a tough material part with a uniform-thickness complicated curved surface. The process comprises the following steps of: 1) cutting a non-metal tough material into a required shape according to the size of the expanded profile of a processed part, and reserving a machining allowance; 2) sewing to connect multiple two-dimensional tough materials in the required shape on a side surface, and then gluing a bottom surface with a part mould; 3) wrapping the mould of the attached tough materials with high-temperature resistant fiber cloth, wrapping a layer of high-strength plastic cloth outside the high-temperature resistant fiber cloth, sealing the boundary with glue, arranging a vacuumizing pipe nozzle and a valve on a non-part forming surface of the mould, and extracting the inside air between the high-strength plastic cloth and the high-temperature resistant fiber cloth as well as between the tough materials and the part mould by the vacuumizing pipe nozzle and a one-way valve at the same time to form a negative high pressure, so that the sewn uniform-thickness tough materials are closely attached to the part mould with a certain complicated curved surface under uniform stress; and 4) heating the integral material and mould in the step 3, and curing and forming to obtain a part with a complicated curved surface, which is consistent with the part mould with the complicated curved surface in shape. Through the wrapping of the high-strength plastic cloth and the vacuumizing, the process realizes uniform stress of external adsorption force, thus reducing the damage of the materials, and ensuring tender and uniform stress and good attachment.
Description
Technical field
The present invention relates to the complex-curved toughness material part of a kind of uniform thickness curing process, be applicable to the complex-curved curing process method of equal thickness of non-metal honeycomb material or nonmetal glass fiber compound material, belong to nonmetallic materials moulding process field.
Background technology
Complex original curved surface toughness material curing process method is cut into required form after toughness material is reserved certain post-production surplus according to the expansion external form of part to be processed; Be fitted on the part mould tire with the tight splicing of two-dimentional toughness material of these a plurality of required forms or with double faced adhesive tape then; Treat to be solidified into and mould tire one after glue is done, wait until processing.If it is complex-curved and when must not be thickness during now processed toughness material; Curing originally is used for complex-curved last time, and it is inhomogeneous to cause fitting, and often causes the peeling that comes unglued; And in the process of solidifying owing to not being that the pressure that receives of plane is inhomogeneous, solidification effect is very poor.
Summary of the invention
The technical problem that the present invention will solve provides the complex-curved toughness material part of a kind of uniform thickness curing process; The parcel of this technology utilization highstrenghtpiston cloth and vacuumizing makes the absorption affinity that adds stressed evenly, not only reduces the damage of material; And stressed soft even, the applying degree is good.
For overcoming the above problems, concrete technical scheme of the present invention is following: the complex-curved toughness material part of a kind of uniform thickness curing process is characterized in that may further comprise the steps:
1) nonmetal toughness material is cut into required form according to the size of the expansion profile of part to be processed, reserves allowance simultaneously;
2) the two-dimentional toughness material of a plurality of required forms is sewed up connection on the side, bottom surface and part mould tire glued joint then;
3) wrap up with the mould tire of high-temperature fibre cloth the toughness material that posts; Its outside is wrapped up one deck highstrenghtpiston cloth again; The glue envelope is carried out on the border; Non-part molded surface setting at the mould tire vacuumizes ozzle and valve, and through vacuumizing between ozzle and the one-way cock highstrenghtpiston's cloth and high-temperature fibre cloth with inside, the air between toughness material and the part mould tire is taken away simultaneously; Form negative high voltage, fit tightly on certain complex-curved part mould tire after making the toughness material of the equal thickness after the stitching evenly stressed;
4) with the moulding that is heating and curing of the integral material in the step 3 and mould tire, form and the consistent complex curved surface parts of complex curved surface parts mould tire external form.
The complex-curved toughness material part of this uniform thickness curing process has adopted the compressed format that vacuumizes, apply external force and reduced damage than adding rigid material material, and the specific rigidity material execute external force stressed soft evenly, the applying degree is good.

The specific embodiment
The complex-curved toughness material part of a kind of uniform thickness curing process, figure is as shown in Figure 1 for this part external form, it is characterized in that may further comprise the steps:
1) a plurality of nonmetal toughness materials are cut into required form according to the size of the expansion external form of part to be processed, as shown in Figure 2, reserve allowance simultaneously, these difform two-dimensional sheet toughness materials satisfy different thickness requirements respectively;
2) the two-dimentional toughness material of above-mentioned a plurality of required forms is sewed up connection on the side, be fitted on the part mould tire at double faced adhesive tape on the bottom surface then;
3) as shown in Figure 3, with high-temperature fibre cloth will fit the mould tire parcel of toughness material good after, its outside is wrapped up one deck highstrenghtpiston cloth again; The glue envelope is carried out with the 3M adhesive tape in the border; Non-part molded surface setting at the mould tire vacuumizes ozzle and valve, through vacuumizing between ozzle and the one-way cock highstrenghtpiston's cloth and high-temperature fibre cloth with inside, between high-temperature fibre cloth and the toughness material; Air between toughness material and the part mould tire is taken away simultaneously; Form negative high voltage, fit tightly on certain complex-curved part mould tire after making the toughness material of the equal thickness after the stitching evenly stressed, guarantee the intact applying of toughness material and part mould tire;
4) with the moulding that is heating and curing of the integral material mould tire in the step 3, according to the performance decision heat time heating time of glue, the external form and the consistent complex curved surface parts of complex curved surface parts mould tire external form of the toughness material of heating back curing molding and complex-curved part fetal membrane.
