Embodiment 1

[0018] a kind of like figure 1 The Z-direction reinforced sandwich composite material includes an upper surface layer 1, a lower surface layer 2 and a core layer 3 in the middle, and the upper surface layer 1, the core layer 3 and the lower surface layer 2 are repeatedly penetrated through the upper surface layer, the core layer and the lower surface layer. The piercing yarn 5 is fixedly connected, the penetration angle of the yarn 5 is between 0-180°, preferably 45° and 60°, and the piercing action is completed by the needle loom 4. Its preparation method is as follows, it comprises the following steps,

[0019] The first step is to determine the materials of the upper surface layer, the core layer and the lower surface layer. In this embodiment, the upper surface layer and the lower surface layer are selected from fabrics, and the core layer is selected from structural core materials, and the above materials are laid, flattened and aligned in sequence;

[0020] The second s...

Embodiment 2

[0023] When setting the parameters of the acupuncture machine, the acupuncture needle distance is 20mm, the puncture angle is 60°, the core material thickness is 25mm, and the speed is 1m / min for puncture, and repeat the acupuncture back and forth after each acupuncture back and forth.

Embodiment 3

[0025] When setting the parameters of the acupuncture machine, the acupuncture needle distance is 25mm, the puncture angle is 45°, the core material thickness is 30mm, the speed is 2m / min, and then the puncture operation is performed, and the tuck action is performed after each puncture action. Form a node, which can be hollow or solid.

[0026] The type and weight of the surface material and core material of the present invention can be selected according to actual needs; the needle pitch refers to the distance between two adjacent Z-direction fibers; the product prepared by the present invention has strong designability, and can be obtained by The type of reinforcement, core material, and the design of geometric and physical parameters realize the design of stiffness and strength of sandwich structural composites. Core material includes but not limited to, balsa wood (Balsa wood), polyurethane foam (PUR), polystyrene foam (PS), polyvinyl chloride foam (PVC), polyethylene foa...

Abstract

The invention discloses a Z-direction enhanced interlayer composite material and a preparation method thereof. The Z-direction enhanced interlayer composite material comprises an upper surface layer,a lower surface layer and a core layer located between the upper surface layer and the lower surface layer, wherein the upper surface layer, the core layer and the lower surface layer are fixedly connected through a puncturing yarn which repeatedly penetrates through the upper surface layer, the core layer and the lower surface layer in a penetration angle of 0-180 degrees. The production processhas the beneficial effects that the machining is simple, and the Z-direction enhanced interlayer composite material which has relatively strong designability and meets the rigidity and strength requirements can be prepared.

Description

Technical field: [0001] The invention relates to a sandwich structure composite material, in particular to a Z-direction reinforced sandwich composite material and a preparation method thereof. Background technique: [0002] In order to realize the Z-direction reinforced structure, that is, the mechanical strength in the thickness direction of the upper layer, the lower layer and the central layer, the existing sandwich composite materials are often realized by bonding each layer or vacuum-assisted forming. For example, the application announcement number is CN103786374 A , the application date is May 14, 2014, a sandwich structure composite plate with reinforcing ribs and its processing technology, with a plate-shaped core material wrapped by a glass fiber reinforced plastic panel, characterized in that the surface of the core material Set up vertical and horizontal connecting grooves, the distance between the vertical connecting groove and the horizontal connecting groove ...
