Embodiment 1

[0031] Such as figure 1 The width of the lower surface 1 is the width of two finished products. The material is a unidirectional tape made of pre-impregnated continuous fibers, and then a thermoplastic composite material is designed through multi-directional layup. Because the lower surface 1 is not used as a functional surface, There is no coating layer and PET protective film, the thickness is thinner than the upper surface 5, and the peeling is better than the upper part. Place the honeycomb core 2 on the lower surface 1, and two honeycomb cores 2 can be placed into the machine at the same time. The width can be customized according to requirements. , the material is polypropylene, and the tubular shape is hexagonal honeycomb or circular honeycomb. In order to improve the compression resistance and impact resistance, the density of the larger honeycomb core can be selected. What is used in this embodiment is 100-110Kg / m 3 honeycomb core with the highest density; in the midd...

Embodiment 2

[0037] Such as image 3 The structure is the same as in Example 1, the difference is that the feeding method is different.

[0038] The specific steps of this embodiment are as follows:

[0039] S1: The upper and lower surfaces are made of continuous fiber-reinforced thermoplastic materials. The upper surface 5 includes 4 layers of continuous fiber-reinforced thermoplastic materials, and the surface has a layer of pp coated surface and a corona-treated PET protective film. The lower surface 1 is Two layers of continuous fiber-reinforced thermoplastic material, with a layer of low-temperature adhesive film 4 between the upper surface and the honeycomb core, and a honeycomb panel made by compounding the upper and lower surfaces with the honeycomb core 2 through thermal compounding process, the density of the selected honeycomb core 2 is 108kg / m 3 .

[0040] S2: There is a layer of low-temperature adhesive film 4 between the upper surface 5 and the honeycomb core 2. Because th...

Abstract

The invention belongs to the technical field of continuous fiber high-strength composite cellular boards, and discloses a cellular board with sealing edges and a preparation method thereof; wherein upper and lower skins of the product cellular board are continuous fiber reinforced thermoplastic composite material layers, the surface of the upper skin is provided with a lamination surface and a protective film, the middle structure is a polypropylene cellular core, two sides of the cellular core are provided with polypropylene edge sealing strips, and the edge sealing strips are in a lock catch type. The problem that a certain gap is formed between two edge sealing materials when finished products are compounded can be solved; the preparation method comprises the following steps: preparing the upper surface and the lower surface from the continuous fiber reinforced thermoplastic material, and compounding the upper surface and the lower surface with the cellular core through a thermal compounding process to prepare the cellular board; laying edge sealing materials circularly on the two sides of the cellular core, so that the edge of each cellular core is attached to the edge sealing materials; setting working parameters of a compound machine, carrying out equipment heating and heat preservation for fixed time, conveying the cellular board laid with the edge sealing material into the compound machine through a conveying belt to be subjected to thermoplastic compounding, and obtaining the cellular board with the sealing edges.

Description

technical field [0001] The invention belongs to the technical field of continuous fiber high-strength composite honeycomb panels, in particular to a honeycomb panel with edge sealing and a preparation method thereof. Background technique [0002] Continuous fiber-reinforced thermoplastic honeycomb panels are composed of continuous fiber prepreg tape multi-directional laminates and polypropylene honeycomb core thermoplastics. Because of their advantages of light weight, compression resistance, high strength and impact resistance, they are widely used in Many technical fields, such as caravans, battery guards, compartment panels, bus floors, containers, etc., and the present invention is mainly used in the construction field. With the development of the construction industry, lightweight and high-strength construction templates are becoming more and more The more attention is paid to it, but the traditional building templates are mostly wooden boards, which are heavy in weight...
