Abstract
The invention discloses a composite grating reinforced structure forming tool. The forming tool comprises a plurality of composite flat plates and a shell wall plate. The adjacent flat plates form 60-degree included angles and are connected through corner plates to form a stable grating structure. The grating and the shell wall plate are glued into a whole. According to a manufacturing method of the composite grating reinforced structure forming tool, the advantage of the low thermal coefficient of expansion of a composite is used, and the thermal deformation problem of composite products is solved, so that the purpose of improving the precision of the composite products is achieved. The precision of a molded surface of a composite reflector manufactured through the composite tool can be within 0.1 mm, and the design requirement is met.
Description
Technical field
The invention belongs to manufacture technology of composite material field, particularly to a kind of grid-stiffened composite structure forming frock and manufacture method.
Background technology
Along with composite is in the fast-developing application of aerospace field, composite is only used as structural member can not meet high-tech requirement, structure/functional composite material is extensively applied at aerospace field, and this just requires that the composite accuracy of manufacture need to bring up to a higher grade.Under this demand, traditional metal forming frock cannot meet multiple material high-precision requirement.Composite frock is widely used owing to thermal coefficient of expansion is consistent with composite products, and solving metal frock thermal expansion well affects problem to high accuracy composite products.
Summary of the invention
The present invention solves the technical problem of composite thermal deformation, propose a kind of grid-stiffened composite structure forming frock and manufacture method, it is possible to the precision of part is effectively ensured.
For solving the problems referred to above, the present invention adopts the technical scheme that: a kind of grid-stiffened composite structure forming frock, including some pieces of composite material flat plates 1 and housing wallboard 2, forms 60 ° of angles, and is connected by gusset plate 3, formed and stablize grid 4 structure between described flat board 1；Described grid 4 is integrated with housing wallboard 2 splicing.
Preferably, described housing wallboard 2 is formed by composite.
A kind of grid-stiffened composite panels forming frock manufacture method, comprises the steps:
Step one: housing wallboard 2 curing molding on stage die；
Step 2: flat board 1 is curing molding in flat board frock；
Step 3: flat board 1 otch；
Step 4: flat board 1 assembles, is inserted mutually by the notch held successfully；
Step 5: between flat board 1, angle structure glue splicing gusset plate 3 is connected, and forms grid 4；
Step 6: grid 4 is put into housing wallboard 2 combination of lumens；
Step 7: grid 4 and housing wallboard 2 glued joint, solidify, forms composite frock；
Step 8: composite frock profile type is processed.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of grid-stiffened composite structure forming frock of present invention offer and manufacture method, utilize the advantage that composite coefficient of thermal expansion is low, solves composite products thermal deformation problem, thus reaches to improve the purpose of composite products precision.Within the composite reflector type surface accuracy of the composite frock manufacture used can reach 0.1mm, meet design requirement.
