Abstract

The invention discloses a kind of high temperature resistant radome tendon and vessel structures for preventing delamination, including upper covering, lower covering and honeycomb interlayer, upper covering and lower covering distinguish paving in the upper and lower surface of honeycomb interlayer, upper covering, there are several glass fiber bundles along the setting of honeycomb interlayer thickness direction between honeycomb interlayer and lower covering, glass fiber bundle is in upper covering and lower skin-surface is horizontal and vertical is alternately arranged, upper covering and the equal paving layer of glass cloth of lower skin-surface, invention increases the intensity of radome thickness direction, improve the force-bearing situation that glue film bonding force is only relied between radome covering and honeycomb, simultaneously, criss-cross tendon and vessel structure avoids intensity missing caused by certain mass of fibers beam is broken, solving radome and having an accident will appear initial lamination defect and gradually extends after impact, radome is caused to lose carrying Ability, the problem of affecting aircraft normal service.

Description

A kind of high temperature resistant radome tendon and vessel structure for preventing delamination
Technical field
The present invention relates to radome Lightning Prevention Technique field, in particular to a kind of high temperature resistant radar for preventing delamination Cover tendon and vessel structure.
Background technique
Most of military radar cover structure is honeycomb sandwich construction, and the bonding between honeycomb interlayer radome covering and honeycomb is strong Degree is the weak structure of radome, and when the load that radome is born beyond expection will appear initial lamination defect, initial layering is lacked It is trapped under external load effect and gradually extends, after expanding to a certain range, radome just loses bearing capacity, is tieed up It repairs, affects the normal service of aircraft.
Occur and extend currently, radome can only prevent layering from the glue film adhesive strength increased between covering and honeycomb, This method can not only reduce the Electro-magnetic Wave Penetrate performance of radome, while increase the weight of radome, it is therefore desirable to new structure To prevent the extension of layering.
Summary of the invention
Present invention solves the technical problem that: a kind of high temperature resistant radome tendon and vessel structure for preventing delamination is provided, to It solves radome and has an accident to will appear initial lamination defect and gradually extend after impact, radome is caused to lose carrying energy Power, the problem of affecting aircraft normal service.
Technical solution of the present invention:
A kind of high temperature resistant radome tendon and vessel structure for preventing delamination, including upper covering, lower covering and honeycomb interlayer, on Covering and the difference paving of lower covering have between the upper covering, honeycomb interlayer and lower covering in the upper and lower surface of honeycomb interlayer Several glass fiber bundles along the setting of honeycomb interlayer thickness direction, the glass fiber bundle is in upper covering and lower skin-surface Horizontal and vertical to be alternately arranged, described upper covering and the equal paving layer of glass cloth of lower skin-surface.
The transversely arranged glass fiber bundle length of the upper skin-surface is the glass fiber bundle length of longitudinal arrangement Half, the glass fiber bundle length of the lower skin-surface longitudinal arrangement are transversely arranged glass fiber bundle length Half.
The glass fibre area of beam is rectangle, the cross-sectional length 2mm, cross-sectional width 0.1mm.
The glass fiber bundle is the glass fiber bundle after impregnated phenolic resin.
Beneficial effects of the present invention: a kind of high temperature resistant radome tendon and vessel structure for preventing delamination is provided, by upper There are several glass fiber bundles along the setting of honeycomb interlayer thickness direction, glass fibre between covering, honeycomb interlayer and lower covering Beam is in upper covering and lower skin-surface is horizontal and vertical is alternately arranged, and increases the intensity of radome thickness direction, improves thunder Up to the force-bearing situation for only relying on glue film bonding force between cover covering and honeycomb, meanwhile, criss-cross tendon and vessel structure avoids a certain The missing of intensity caused by bundle fiber beam is broken, solving radome and having an accident will appear initial lamination defect and gradually after impact Extension, the problem of causing radome to lose bearing capacity, affect aircraft normal service.
Detailed description of the invention
Fig. 1 is tendon and vessel structure radome diagrammatic cross-section of the present invention;
Fig. 2 is radome surface fiber tendon and vessel schematic diagram of the present invention;
It is identified in figure: 1, upper covering, 2, honeycomb interlayer, 3, glass fiber bundle, 4, glass fabric, 5, lower covering.
Specific embodiment
The present invention is described further with reference to the accompanying drawing, it is as shown in Figures 1 and 2, of the present invention a kind of pre- The high temperature resistant radome tendon and vessel structure of anti-delamination, including upper covering 1, lower covering 5 and honeycomb interlayer 2, upper covering 1 and lower illiteracy Skin 5 distinguishes paving in the upper and lower surface of honeycomb interlayer 2, has several between the upper covering 1, honeycomb interlayer 2 and lower covering 5 Along the glass fiber bundle 3 of 2 thickness direction of honeycomb interlayer setting, the glass fiber bundle 3 is on 5 surface of upper covering 1 and lower covering Horizontal and vertical to be alternately arranged, described upper covering 1 and the lower equal paving layer of glass cloth 4 in 5 surface of covering.
Transversely arranged 3 length of glass fiber bundle in 1 surface of upper covering is 3 length of glass fiber bundle of longitudinal arrangement Half, 3 length of glass fiber bundle of described 5 surface longitudinal of the lower covering arrangement is transversely arranged glass fiber bundle 3 The half of length, for the above covering 1, as shown in Fig. 2, transversely arranged 3 length of glass fiber bundle is d, longitudinal arrangement 3 length of glass fiber bundle be 2d, such arrangement mode can be avoided overlapping between transverse fiber beam and longitudinal fiber bundle plus Increase thickness, keeps the smooth of radar cover outer surface, any two rows of transversely arranged glass fibres on upper covering 1 and lower covering 5 Spacing between beam 3 is 3d, and the spacing between the glass fiber bundle 3 of any two rows longitudinal arrangement is 3d, such arrangement mode energy It enough realizes that the spacing between the glass fiber bundle 3 of radome thickness direction is identical, increases the uniformity of stress, avoid because a certain The glass fiber bundle 3 of root thickness direction is loaded excessive and damages.
3 section of glass fiber bundle is rectangle, and the cross-sectional length 2mm, cross-sectional width 0.1mm are such The fibre bundle for connecing cross-sectional area not only can increase the bearing capacity of glass fiber bundle, but also can reduce glass fiber bundle and cover on radome Epidermis face and lower surface skin-surface protrusion realize the smooth of radome surface, and glass fiber bundle 3 is after impregnated phenolic resin Glass fiber bundle 3 effectively increases the heat resistance of tendon and vessel structure of the present invention.
