specific Embodiment approach 1

[0018] Specific implementation mode one: combine Figure 1-Figure 4 Explain that the core material of this embodiment includes a plurality of connecting strips 1, the thickness of which is equal to that of the plurality of connecting strips 1, and each connecting strip 1 is formed by connecting a plurality of 'X'-shaped units 2 sequentially along the transverse top end, and 'X' There is a notch 3 above the intersection of the 'shaped unit 2, and the width of the notch 3 is equal to the thickness of the connecting strip 1. A plurality of connecting strips 1 are divided into two groups and are respectively defined as a horizontal group and a vertical group. The horizontal group and the The number of connecting bars in the longitudinal group is equal, the connecting bars 1 in the horizontal group are arranged in parallel at equal intervals in turn, and the connecting bars 1 in the longitudinal group are vertically arranged with the connecting bars 1 in the corresponding horizontal...

specific Embodiment approach 2

[0019] Embodiment 2: The thickness of each connecting bar 1 in this embodiment is 0.1-10mm, and other method steps are the same as Embodiment 1.

specific Embodiment approach 3

[0020] Specific implementation mode three: combination figure 2 Explain that each 'X'-shaped unit 2 in this embodiment is composed of the first rod 2-1 and the second rod 2-2 at the upper part and the third rod 2-3 and the fourth rod 2-4 at the lower part, The first bar 2-1 and the fourth bar 2-4 are arranged in parallel, the second bar 2-2 and the third bar 2-3 are arranged in parallel, the first bar 2-1, the second bar 2-2, the third bar 2 -3 and the width of the fourth bar 2-4 are equal, and the advantage of this structure is that the energy absorption capacity is strong. Other method steps are the same as those in the first or second embodiment.

Abstract

The invention discloses a core material of a dot matrix laminboard and a core material manufacturing method by using extruding and interlocking, and relates to a core material of the laminboard and a manufacturing method for the core material. The invention aims to solve the problems that the preparation technology of the conventional core material of the dot matrix laminboard is complicated, the cost is high, and the core material is difficultly produced in batches. According to a scheme I, each connection strip is integrated by a plurality of X-shaped units which are sequentially connected with one another; notches are formed above the intersections of the X-shaped units; two groups of connection strips are perpendicular to each other and are clamped with each other through the notches. According to a scheme II, each connection strip comprises a plurality of V-shaped units and a plurality of connectors; the connection strips in two groups are clamped with each other through first notches and notches in the connectors. According to a scheme III, connection plates are extruded; the connection plates in the step 1 are cut into connection strips with the equal thicknesses; the two groups of connection strips are perpendicular to one another and are clamped with one another through the notches. According to a scheme IV, the difference from the scheme III is that the connection strips in the two groups are clamped with one another through the first notches and the notches in the connectors. The core material is used for preparing the dot matrix laminboard.

Description

technical field [0001] The invention relates to a core material of a sandwich panel and a manufacturing method thereof. Background technique [0002] At present, there are mainly the following methods for preparing metal lattice sandwich structural panels: investment casting method, stamping folding brazing method, wire weaving method, pultrusion discharge cutting method. The problems existing in the above methods are described respectively below. 1. Investment casting method: use injection molding technology to make the panel and core separately into polystyrene sacrificial mold prototypes, and then assemble these sacrificial molds to prepare sand molds; sacrificial polystyrene at high temperature The mold melts and decomposes to form voids with octahedral lattice in the sand mold; finally, the high-temperature molten aluminum alloy is slowly injected into the sand mold, and the sand mold is destroyed after cooling to obtain the octahedral lattice material. Disadvantages ...
