Abstract

The invention discloses a hard honeycomb core and a bonding and forming method thereof by adopting strips. The lining bonding and forming method comprises the following steps of: bonding hard sheets together by using flexible strips, then overlaying and bonding to form a honeycomb core block, and finally expanding the honeycomb core block to form the honeycomb core. The hard honeycomb core can be widely applied to producing sandwich structure products in various fields.

Description

Hard honeycomb core and lead-in bonding forming method thereof

The invention belongs to composite material sandwich structure and make the field with honeycomb core, particularly relate to the hard sheet material with the bonding method that manufactures honeycomb core of the flexible strip that serves as a contrast.

At present, the honeycomb structure composite material has light weight, intensity is big, rigidity is high, have functions such as buffering, shock insulation, insulation, heat insulation and sound insulation, obtain extensive use, it is applied to aerospace field the earliest, be widely used in fields such as building industry, car and boat manufacturing industry, furniture manufacturing, packing and transport service now, in order to alternative metals, plastics, timber, clay brick and highly foamed polystyrene etc.For satisfying the user demand of variety classes honeycomb structure composite material, there to be many kinds of honeycomb cores to be designed, to produce, mainly contain: paper honeycomb core, frp honeycomb core, cotton honeycomb core, aramid fiber honeycomb core, aluminium honeycomb core, various plastic honeycomb core, die mould steel honeycomb core or the like.These honeycomb cores all adopt homogeneous material to produce, paper honeycomb core low price application area is wider, but a variety of causes such as its protection against the tide, waterproof, fire prevention and intensity index have all limited its application area, die mould steel honeycomb core is to adopt the whole piece steel plate to be pressed into behind the ladder type welding or bond together, various aspects of performance such as intensity are all fine, but not flexible suitable plane sandwiched product, this has limited its application in various curved surface use occasions.Aspect of performances such as the compressive strength of other honeycomb core and temperature tolerance are limited, and price is more expensive, and these all are that these honeycomb cores of these particular application such as its obstacle, particularly High Voltage of enlarging application area, high temperature, shaped face are inefficient.

The objective of the invention is in order to overcome the shortcoming of above-mentioned honeycomb core, adopt a kind of forming method that one or more hard sheet made are become hard honeycomb core.The hard material that we use is now compared with above-mentioned honeycomb core material therefor has very high compressive strength and resistance to heat, the compressive strength of hard honeycomb core can design by usage requirement, hard material is of a great variety, as: the steel plate class, the cast iron class, ceramic-like, alloy type, the non-ferrous alloy class, the cement class, category of glass, bamboo wood class, all hard materials of rock type or the like, performance and price are different, the honeycomb core of different hard material manufacturings has different performances, choose one or more hard material collocation by the performance of usage requirement, one chooses suitable compositional system surely, produce the suitable hard honeycomb core of price, these hard honeycomb cores can satisfy the flat clevis layer cellular structure of various material panels, the demand of special-shaped interlayer cellular structure.

The present invention adopts following technical step for achieving the above object: at first one or more hard sheets of the same a kind of specification that will use are ready to; Select the flexible strip of satisfying the demand for use; Then use with a kind of hard sheet or multiple hard sheet and become the hard sticky object by design sequence and flexible strip are bonding; In the rule gluing of the corresponding hard sheet of hard sticky object being pressed four times of sheet width; And make it back and forth to fold into and need thickness to cut off; Pressurize as required, heating or pressurized, heated be solidified into hard sticky object honeycomb pellet; This honeycomb pellet is fit to the uniform thickness plane or curved surface sandwich structure is used.Also can arrange one or more hard sheets of the different size that will use in proper order by use; Select the flexible strip of satisfying the demand for use; Then use with a kind of different size hard sheet or multiple different size hard sheet to become the hard sticky object, of the rule gluing of the corresponding hard sheet of hard sticky object by four times of sheet width by design sequence and flexible strip are bonding; And make it back and forth to fold into and need the thickness end socket to cut off; Pressurize as required, heating or pressurized, heated become hard sticky object honeycomb pellet; This honeycomb pellet is fit to sandwich structurees such as non-uniform thickness concave and convex plane, inclined-plane or concave-convex curved surface, inclined-plane curved surface to be used.Four times of gluings are meant that sheet width equates with the regular hexagon honeycomb is monolateral, are three times of sheet width if select the monolateral width of regular hexagon honeycomb, and then the gluing width should be 4 * 3=12 doubly, the adjacent layer gluing half-distance that staggers; The adhesive tape width is slightly less than monolateral width.Other pattern honeycomb core can calculate the width rule and the gluing rule of thin slice by design pattern.The honeycomb pellet can directly stretch as modular honeycomb core plate, also can be stretched as continuous honeycomb core through continuous splicing lengthening and use; Widen through lengthening and can satisfy all usage requirements.The width that back and forth is folded into each layer of honeycomb pellet can equate, also can be unequal.Heating process is to determine by the requirement of used adhesive, but as the needs gluing, folding again after the heating.

The invention has the beneficial effects as follows: the performance of hard material and flexible strip material is all fully played, and has accomplished mutual supplement with each other's advantages, and this has improved utilization efficiency of material widely, also uses for the hard material light simultaneously to lay the foundation.Flexible strip makes it not only can make the plane comb core material facility that can make the curved surface comb core material also is provided.The flexible strip of whole honeycomb pellet is not cut off, and this has improved the overall performance of honeycomb pellet greatly, some occasion honeycomb core need not spray adhesive curing just directly composite cover become cellular board and use.Can be used as raw material of building materials such as making building wall board, floor, roofer and can reduce the building deadweight greatly, create conditions for reducing support system.Use as various man-made board honeycomb core plates, can reduce consumption greatly, alleviated environment damage simultaneously wood materials.
