Embodiment 1

[0029] A composite plate, comprising an upper surface layer 1, a lower surface layer 2 and a core layer 3, characterized in that: the core layer 3 is a disc-shaped blister-shaped core plate, and the cross-section of the core plate is a W-shaped disc The structure of the W-shaped blister 4, the center of the frustum of the W-shaped blister 4 is pointed, and each W-shaped blister 4 forms a disc element, which protrudes up and down with the core plate surface as the center. A cone and a cone ring, as shown in Figure 2(a) and Figure 3(a). The W-shaped discs produced by calendering are parallel and symmetrically distributed on the surface of the core plate in a lattice manner to form a disc-shaped blister-shaped core plate, as shown in FIG. 7 . Other lattice distributions of butterfly elements are shown in Figure 8, Figure 9, and Figure 10. The formed composite panel structure can be a single-layer or multi-layer structure, and the directionality of the unit structure can be used ...

Embodiment 2

[0031] A composite plate, comprising an upper surface layer 1, a lower surface layer 2 and a core layer 3, characterized in that: the core layer 3 is a disc-shaped blister-shaped core plate, and the cross-section of the core plate is a WV-shaped disc The structure of the WV-shaped blister 4 is spherical, and each WV-shaped blister 4 forms a disc element, which protrudes up and down centered on the surface of the core plate. A combination of a truncated cone and a spherical crown and a combination of a truncated cone and a ring, as shown in Figure 2(b) and Figure 3(b). The WV discs produced by calendering are parallel and symmetrically distributed on the surface of the core plate in a lattice manner to form a disc-shaped blister-shaped core plate, as shown in FIG. 7 . Similarly, the dot matrix distribution of the WV dish can also adopt the manners shown in Fig. 8 , Fig. 9 and Fig. 10 . The formed composite board structure can be a single-layer or multi-layer structure, and the...

Embodiment 3

[0033]A composite plate, comprising an upper surface layer 1, a lower surface layer 2 and a core layer 3, characterized in that: the core layer 3 is a disc-shaped blister-shaped core plate, and the cross-section of the core plate is a WU-shaped disc Shaped blister 4 structure form, each WU-shaped disc-shaped blister 4 forms a disc unit, and the disc unit forms a combination of a convex conical frustum and a ring with the surface of the core plate as the center, as shown in Figure 2 (c) and Figure 3(c). The WU-shaped discs produced by calendering are parallel and symmetrically distributed on the surface of the core plate in a lattice manner to form a disc-shaped blister-shaped core plate, as shown in FIG. 7 . The upper indentation and the lower indentation of the WU-shaped dish-shaped blister 4 form two closed airbag structures with the upper surface layer 1 and the lower surface layer 2 respectively. Similarly, the dot matrix distribution of the WU-shaped dish can also be in ...

Abstract

A dish type core layer sandwich plate and the use thereof, the plate includes an upper surface layer, a lower surface layer and a core layer and is characterized in that the core layer is a dish type bubble-cap shape core plate, the section of the core plate is cone platform type dish type bubble-cap structure form, each dish type bubble-cap forms a dish member, the dish members are symmetric and parallel in distribution in dot array mode, and the cone platform heart part of the cone dish type bubble-cap can be sharp top shape, flat top shape and annular top shape. The dish member formed by calendering is distributed with two symmetric outer convex inner concave bubble-caps choosing the core layer surface as center to form a spatial two staged unit combination structure. By decorating the cone dish type bubble-cap, the cone platform structure with W type, WV type and WU type sections can be formed. The formed composite board structure can be single layer or multi-layer structure, can use the directionality of the unit structure and adapts apposition, folding and mixture multiple layer spatial combinations. The plate is used for manufacturing the industrial products having the object of press resistance, buffer, vibration insulation, sound isolation, heat insulation, and heat preservation.

Description

1. Technical field [0001] The invention relates to the structure of a composite board, in particular to a sandwich board structure of a multilayer composite board. It is mainly used as the core structure for packaging cardboard, and can also be used for the core structure of building wall panels, floors, and partitions, the core structure of the shell, wall panels, floors, and partitions of vehicles, ships, and airplanes, and other Core layer for sandwich panel industrial products for the purpose of compression resistance, cushioning, vibration resistance, sound insulation, heat insulation, heat preservation, etc. 2. Background technology [0002] In order to save resources, improve the utilization of materials, and reduce the weight of products, many panels are now using composite panels. According to different materials, composite panels can be divided into metal composite panels, aluminum-plastic composite panels, non-metal composite panels, wood composite panels and pap...
