Abstract
The utility model aims at providing a thick honeycomb work piece of big camber. The utility model discloses the technological solution that adopts is a thick honeycomb work piece of big camber, comprises at least three -layer inlayer honeycomb, is provided with the preimpregnation material between the adjacent inlayer honeycomb, preimpregnation material about the surface be provided with the glued membrane, the inlayer honeycomb include overstretching honeycomb and regular hexagon honeycomb, be connected through the expanded polystyrene (EPS) between overstretching honeycomb and the regular hexagon honeycomb.
Description
Technical field
This utility model belongs to honeycomb sandwich board technical field, particularly relates to a kind of deep camber thickness honeycomb workpiece.
Background technology
Honeycomb sandwich board has the high and low density of specific stiffness, corrosion-resistant, shock resistance, heat insulation, sound insulation and the advantage of vibration damping, it is widely used in aerospace field, the structure member such as such as fuselage wallboard, engine charge nacelle, undercarriage door, driving cabin, cargo hold, tailplane, leading edge of a wing.
Due to part self load and the requirement of contours profiles, partial cell sandwich part is designed to deep camber, the version of regular hexagon thickness honeycomb (thickness >=30mm) according to actual needs, but this form brings challenge greatly and difficulty to manufacture, because regular hexagon honeycomb cannot be fitted completely with the forming frock of deep camber, if the large area tear of patch die face honeycomb core lattice must be caused by force with pressure potential.Mechanics limitation due to overstretching honeycomb, it is impossible to all replace regular hexagon honeycomb with overstretching honeycomb.
Summary of the invention
The defect that this utility model exists to overcome prior art, the purpose of this utility model is to provide a kind of deep camber thickness honeycomb workpiece.
The technical solution that this utility model is used is a kind of deep camber thickness honeycomb workpiece, it is made up of at least three layers of internal layer honeycomb, it is provided with prepreg between adjacent internal layer honeycomb, described prepreg upper and lower surface is provided with glued membrane, described internal layer honeycomb includes overstretching honeycomb and regular hexagon honeycomb, is connected by foamed glue between described overstretching honeycomb and regular hexagon honeycomb.
Described overstretching honeycomb is arranged on the curvature position more than 30 °, and described regular hexagon honeycomb is arranged on the position of 30 ° that curvature is not more than.
Prepreg bottom the bottom of described internal layer honeycomb is overlapped with non-skid band, is provided with glass fabric bottom prepreg.
Compared with prior art, this utility model is had the beneficial effect that
1: be plated in by interlayer honeycomb and be plated in the conformal problem efficiently solving deep camber honeycomb and forming frock with honeycomb in layer.
2: improve the viscosity of honeycomb and forming frock by arranging 1 layer of Woven glass cloth cloth, not only solve viscosity, be also convenient for the demoulding simultaneously.
3: successively, block-by-block be plated in honeycomb.If honeycomb being resolved into dried layer according to total honeycomb thickness, the present invention referred to as interlayer honeycomb is plated in；Every layer of honeycomb comprehensively uses according to the amount of curvature of part and selects the honeycomb that manufacturability is good and mechanical property is good, and the position big in curvature uses overstretching honeycomb, and the position little in curvature uses regular hexagon honeycomb, and in the present invention referred to as layer, honeycomb is plated in.Interlayer be plated in by glued membrane and prepreg glued joint every layer between honeycomb, transmission load；In layer, honeycomb is plated in and different types of honeycomb block is glued together by foamed glue, effectively solves the conformal problem of honeycomb.

Detailed description of the invention
As depicted in figs. 1 and 2, a kind of deep camber thickness honeycomb workpiece, the honeycomb that 60mm is thick is divided into 3 layers, every layer of 20mm thickness, it is provided with prepreg between adjacent internal layer honeycomb, described prepreg upper and lower surface is provided with glued membrane, and described internal layer honeycomb includes overstretching honeycomb and regular hexagon honeycomb, is connected by foamed glue between described overstretching honeycomb and regular hexagon honeycomb.
Described overstretching honeycomb is arranged on the curvature position more than 30 °, and described regular hexagon honeycomb is arranged on the position of 30 ° that curvature is not more than.
Prepreg bottom the bottom of described internal layer honeycomb is overlapped with non-skid band, is provided with glass fabric bottom prepreg.
At frock external coating releasing agent before curing molding.
Honeycomb curing molding, the honeycomb being plated in encapsulates according to process specification requirements, solidification.
Digital control processing inclined-plane, it is generally the case that the actual interior profile after having solidified has different with the theoretical profile of digital-to-analogue, it is ensured that part profile and the accordance of digital-to-analogue profile, uses Digit Control Machine Tool processing honeycomb inclined-plane after the solidification is complete.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
