Abstract
Grid cloth enhanced polymer honeycomb aluminum composite laminboard, it is a kind of battenboard that polymer grid cloth composite skins and polymer honeycomb aluminium core layer binder course are respectively formed in Aluminum Honeycomb Cores upper and lower surface, and the composite laminboard is divided into five layers from top to bottom, is respectively：Polymer grid cloth composite skins；Polymer honeycomb aluminium binder course；Honeycomb aluminum sandwich layer；Polymer honeycomb aluminium binder course；Polymer grid cloth composite skins.The technology makes the sandwich layer of battenboard and surface layer combine together, and without sharp interface, delamination phenomenon will not occur in loading process epoxy resin surface layer and core body, strengthens the globality of battenboard, and rigidity and intensity are high.The polymer grid cloth composite skins of the battenboard are that the composite bed that grid cloth is formed is added in polymer, due to the presence of grid cloth, improve the plasticity of surface layer, avoid or postpone it brittle fracture occur.
Description
Technical field
The utility model is related to a kind of grid cloth enhanced polymer honeycomb aluminum composite laminboard, available for build, aviation,
Vehicle etc., there is the energy-absorbing safeguard function for withstanding shocks or exploding.
Background technology
Legacy cellular aluminum sandwich panel basic structure is the upper and lower surface stickup or welding unlike material in honeycomb aluminum core body
Panel, the battenboard formed has the characteristics that lightweight, high specific stiffness, high specific strength, and heat-and sound-insulating and energy-absorbing effect are good,
It is widely used in the fields such as aircraft, train, ship and building.
Honeycomb aluminum sandwich panel panel material is different at present, but preparation method mainly has two kinds of gluing and method for brazing.State
Department of Intellectual Property of family is in the patent of invention (publication number of " a kind of honeycomb sandwich panel " disclosed in September in 2013 11 days：
CN103291035A), honeycomb aluminum is connected together by the patent with glass fabric by gluing, forms the folder with three-decker
Core plate：Upper covering is adhesively fixed by adhesive layer and honeycomb core, and lower skinning layer is adhesively fixed by adhesive-layer and honeycomb core.Country
Department of Intellectual Property is in the patent of invention of " a kind of preparation method of aluminium honeycomb core material and cellular board " disclosed in September in 2012 26 days
(publication number：CN102689066A), the patent carries out preparing honeycomb sandwich board using soft solder brazing mode, and main technique is：
Banding or paste soft solder are coated in upper and lower panel side, core is fixed with panel, carries out vacuum drying oven soldering, and temperature rises to
280 to 450 degrees Celsius.Nian Jie or weldering has only been carried out between the core and panel of above honeycomb aluminum sandwich panel at honeycomb hole rib
Connect, contact surface is small, in loading process, when being particularly subject to dynamic loads effect, easily occurs between sandwich board core material and panel
Peel off, influence its mechanical property and applicability.
State Intellectual Property Office is in " the one-piece type composite laminboard of polymer/foam aluminium " disclosed in 23 days July in 2014
Patent of invention (publication number：CN 103935080A), a kind of centre of the patented invention is foamed aluminium sandwich layer, and upper and lower surface is poly-
The one-piece type composite laminboard of the five-layer structure of compound/foamed aluminium composite bed and straight polymer protection surface layer.The battenboard is by gathering
Compound/foamed aluminium composite bed replaces traditional metal faced, enhances globality.This technology is as being applied to honeycomb aluminum sandwich
Plate, then polymer is separated and lose globality by honeycomb aluminum hole rib in polymer honeycomb aluminium composite bed, in loading process
Only polymer facing layer bearing load and show as fragility.
Utility model content
Grid cloth enhanced polymer honeycomb aluminum composite laminboard of the present utility model is one kind two above and below Aluminum Honeycomb Cores
Face is respectively formed the battenboard of polymer-grid cloth composite skins and polymer-honeycomb aluminum sandwich layer binder course, the composite laminboard from
Top to bottm is divided into five layers, is respectively：Polymer-grid cloth composite skins；Polymer-honeycomb aluminum binder course；Honeycomb aluminum sandwich layer；It is poly-
Compound-honeycomb aluminum binder course；Polymer-grid cloth composite skins.
The purpose of this utility model is to provide a kind of grid cloth enhanced polymer honeycomb aluminum composite laminboard, the technology
The sandwich layer and surface layer for making battenboard combine together, will not in loading process epoxy resin surface layer and core body without sharp interface
Generation delamination phenomenon, strengthens the globality of battenboard, and rigidity and intensity are high.Polymer-grid cloth of the battenboard is compound
Top layer is that the composite bed that grid cloth is formed is added in polymer, due to the presence of grid cloth, improves the plasticity of surface layer, avoid or
Postpone it and brittle fracture occur.
The utility model has the following advantages that compared with prior art：
1) covering of traditional battenboard is replaced using polymer-grid cloth composite skins and polymer-honeycomb aluminum composite bed
Surface layer so that do not have sharp interface between the sandwich layer and surface layer of battenboard, be a kind of globality composite laminboard.The technology avoids
Boundary strength is low between core and panel and the cracking that occurs departs from, and without expensive equipment, manufacture craft is simple, into
This is low.
2) technology adds one layer of grid cloth in polymeric surface layer, forms polymer-grid cloth composite skins, not only
The strength and stiffness on top layer are enhanced, plasticity is greatly improved, and solves the brittleness problems on straight polymer top layer.
3) the technology application polymer forms sealing function, moisture-proof anticorrosive as battenboard top layer to honeycomb aluminum sandwich layer
It is good, avoid the etching problem between traditional covering sandwich board finish and core.
