Abstract
A honeycomb core splicing method comprises the following steps: inserting strip-shaped foaming glue satisfying a prescribed strength requirement between the honeycomb core groups or between the honeycomb core of a honeycomb panel and a frame skeleton, carrying out heating expansion of the foaming glue in a high temperature state of a hot pressed plate, carrying out synchronous hot pressing solidification with an adhesive or a glue membrane in the plate making process, and bonding the honeycomb core group or the honeycomb core and the frame skeleton which are butted into a whole body. The splicing method is simple to operate, is suitable for the splicing of honeycomb core groups, and is also suitable for the splicing and reinforcing of the honeycomb core and the frame skeleton; and additionally, the strength of a honeycomb core splicing position is higher than the strength of the body, so the honeycomb panel has a high overall strength and a good rigidity, and can satisfy strength requirements of a honeycomb shelter.
Description
Technical field
The present invention relates to shelter technology field, especially relate to a kind of joining method of honeycomb core.
Background technology
Honeycomb shelter, in making sheet process, is subject to the fabric width restriction of honeycomb core and specifically makes requirement, certainly exists the situation of comb core splicing.
At present, honeycomb core connecting method has following two kinds: 1) take the mode of handspin, have inefficiency, the problem that strength of joint is poor; 2) take to brush the mode of tackiness agent, have the problems such as honeycomb hole contraposition is difficult, and strength of joint is low.Take above-mentioned two kinds of honeycomb cores that mode is spliced, its strength of joint all can not meet the requirement of strength of honeycomb shelter.
CN 102270782 A disclose a kind of joining method of reflection panel in honeycomb sandwich structure, comprising: determine that the shape of aluminium sheet splicing seams and locator means, successively splicing lay three steps of repairing of sandwich structure and splicing seams.In sandwich plate, the shape of the splicing seams of aluminium sheet adopts Great Wall shape, after modeling, the curved surface of splicing is launched respectively to obtain blanking figure, after stock layout processing, obtains and produces blank; This successively splices lays the core process that sandwich structure is sandwich plate manufacture; The repairing of this splicing seams comprises the repairing of working plate splicing seams and the splicing of the simple shear of backboard.This inventive method has solved the problem that panel manufacturing dimension is subject to starting material limitation of size, but its operation steps is many, spliced materials is required high, and the scope of application is little.
CN 103000998 A disclose a kind of splicing construction for super material function plate splicing, splicing construction of the present invention comprises jigsaw and lower jigsaw, between described upper jigsaw and lower jigsaw, be formed with groove structure, described groove structure is for holding two super material function plates intending splicing, and described upper jigsaw and described lower jigsaw are fastenedly connected.The splicing construction complex structure that should splice for super material function plate, and its structure is not suitable for the splicing of honeycomb core.
Summary of the invention
The technical problem to be solved in the present invention is: overcome prior art deficiency, a kind of honeycomb core joining method simple to operate is provided, be applicable between honeycomb core or honeycomb core and peripheral frame skeleton between splicing, and improve the strength of joint of honeycomb core, reach the strength criterion of honeycomb shelter.
The technical scheme that the present invention solves its technical problem employing is: a kind of honeycomb core joining method, step is as follows: between the honeycomb core group of honeycomb sandwich board or between honeycomb core and peripheral frame skeleton, inserting and meeting the strip foamed glue that prescribed strength requires, foamed glue is expanded by heating under the condition of high temperature of hot pressing making sheet, synchronize hot-press solidifying with the tackiness agent of making sheet process or glued membrane, by the honeycomb core group of docking or honeycomb core with peripheral frame skeleton is bonding is integral.
Further, described honeycomb sandwich board is followed successively by outer covering, honeycomb core group, inside panel from outside to inside.
Further, described honeycomb core is NOMEX aramid fiber honeycomb.
Further, described foamed glue is the performed polymer that epoxy resin and whipping agent form.
Whipping agent weight is 1%～2% of foamed glue gross weight.
Beneficial effect of the present invention: this joining method is simple to operate, can not only be applicable to the splicing between honeycomb core group, is applicable to splicing and reinforcement between honeycomb core and peripheral frame skeleton simultaneously; In addition, honeycomb core stitching portion intensity is higher than body intensity, and honeycomb sandwich board bulk strength is high, and good rigidly can meet the requirement of strength of honeycomb shelter.
