Description

Sandwich plate with sandwich-core using deep drawing products or tube flanges, and its manufacturing method}

The present invention relates to a sandwich plate using a deep drawing product or a tube flange as a sandwich inner core, and a method of manufacturing the same. More specifically, the present invention relates to a deep drawing or tube flange process, which is widely used in general industries. The present invention relates to a medium-large and light weight sandwich plate material produced by aligning the manufactured product with a sandwich inner core and bonding the upper and lower outer plate materials, and a method of manufacturing the same.

 Conventional sandwich plate is configured to have a three-dimensional internal structure using a synthetic resin composite material, foam or metal, non-metal. The sandwich panel is manufactured by bonding the surface plate to the upper and lower surfaces of the internal structure of the unit layer. In particular, in the case of ships or large structures, I-beam or corrugate-type structures, which are easily produced in industry, have been manufactured as internal structures. However, such a structure has a problem that can be overdesigned by the anisotropic feature of the structure itself.

Recently, various types of inner truss structures have been studied as sandwich inner cores. Typical examples include pyramids, octets, and kagome structures. In the case of the octet truss structure, each element is connected by an equilateral triangle, so that mechanical properties are constant in all directions. The modified case is the Kagome structure. As shown in the prior art of FIG. 3, the kagome structure is a shape in which two tetrahedral shapes are bonded together. In the case of the embodiment of the figure, since the plate is processed into an uneven structure and used as the inner core of the sandwich plate, when the size of the sandwich plate becomes medium-large, in order to form the entire area of the sandwich inner core plate into the uneven portion as described above, In addition to the need for a line, it is difficult to change the local properties by the individual control of the shape and position of the inner core group, there is a disadvantage that it is very difficult to produce a sandwich plate having a variety of properties and applications.

The present invention was devised to solve such a problem, and by making the sandwich intermediate layer an independent inner core group, for example, a deep drawing product or a tube flange, instead of an integral structure shape, to facilitate the production of medium and large sandwich plates. The purpose of the present invention is to provide a light weight, high strength, highly functional medium and large sandwich plate material and its manufacturing method.

In addition, the separate internal unit core group has the advantage of simplifying the production facilities and productivity in addition to the production of only the unit structure without the need to manufacture the medium-large internal structure as a single unit, there is another purpose to increase the mobility and utilization.

In addition, it is another object to provide a medium and large-sized light weight sandwich plate material having various characteristics and applicability by enabling the change of local physical properties by individually controlling the shape and position of the inner core group.

In order to achieve the above object, according to the present invention, two or more plate-like plate material is coupled by the inner core, two plate material disposed side by side on the upper and lower portions of the sandwich plate; And an inner core disposed on a plurality of plate surfaces between the two plates to support the two plates at a predetermined interval.

The inner core may be a product manufactured by deep drawing processing.

Each of the deep drawing processed inner cores may include one deep drawing processed product, or two or more deep drawing processed products may be connected in series in a direction perpendicular to the two plates.

The inner core may be a tube flange product.

Each of the tube flange inner cores may consist of one tube flange or two or more tube flanges may be connected in series in a direction perpendicular to the two plates.

The sandwich plate may further comprise at least one inner core layer consisting of two plates and a plurality of inner cores supporting therebetween.

The two plates and the inner core may be joined by one or more of welding, brazing, transition liquid phase (TLP), adhesive bonding, and mechanical bonding.

According to another aspect of the present invention, a method for manufacturing a sandwich plate in which two or more plates are joined by an inner core includes: (a) a plurality of plates disposed between two plates to support a distance between the two plates; Processing the inner core; (b) disposing and joining the plurality of inner cores to the surface of one of the two plates, respectively; And (c) placing and joining the other one of the two plates on the inner core.

The inner core may be a product manufactured by deep drawing processing.

This has advantages in terms of weight reduction and manufacturing cost reduction. However, in the case of the I-beam inner structure 113 or the corrugated inner structure 133, the upper and lower outer plates are supported in the longitudinal direction of the inner structure to exhibit high rigidity and strength. The mechanical properties are relatively degraded. In order to satisfy the mechanical properties in the width direction, it is necessary to increase the spatial density of the internal structure or to install a reinforcement around the internal structure. In this case, due to overdesign, there is a problem that the weight reduction ratio, which is an advantage of the original sandwich plate, is reduced.
