Embodiment 1

[0050] The process for preparing Z-direction oriented continuous fiber reinforced honeycomb core material described in this embodiment specifically includes the following steps:

[0051] (1) According to the size requirements of the prepared honeycomb core material, the carrier is installed in advance. There is a vertical plate at the beginning of the carrier, and the rear mold 2 is fixed on the front end of the vertical plate of the table, and the adjacent said The distance between the side walls of the regular hexagonal prisms 4 is 0.5 mm of the wall thickness of the honeycomb to be prepared. The hopper of the extruder is filled with high-density polyethylene pellets, and each heating section of the extruder enters a heating state, and the die size of the extruder is adjusted. Co-extrude and fully mix the polyethylene resin and glass fiber in molten state, based on the total amount of the long fiber material and resin, the mass content of the glass fiber is about 10%;

Abstract

The invention belongs to the field of composite materials, and in particular relates to a Z-direction orientation continuous fiber reinforced honeycomb core material as well as a preparation process and application thereof. The preparation process comprises the following steps: (1) by taking long fibers which are continuous in the Z direction as a reinforcing material, piling according to the shape of the honeycomb core material so as to form the side wall of the honeycomb core material; (2) coating and moistening the fibers by using molten thermoplastic resin; (3) piling the long fiber material and the thermoplastic resin by using an co-extrusion process, cooling and fixing to form the side wall of the honeycomb core material, and repeating the piling process until the honeycomb core material is obtained. As the long fibers are directly adopted as the raw material to produce the honeycomb core material together with the thermoplastic resin in the method, the pressure resistance of the honeycomb core material in the Z direction is further improved, the Z-direction structural strength and the bearing capability of a prepared honeycomb structure core are greatly improved, and the application field is greatly widened.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to a Z-direction oriented continuous fiber reinforced honeycomb core material, and further discloses its preparation process and application. Background technique [0002] Honeycomb originally means honeycomb, which is a hexagonal arrangement (such as figure 1 As shown), one end of it is a hexagonal opening, and the other end is the bottom of a closed hexagonal pyramid, which is composed of three identical rhombuses, so the honeycomb is a strict hexagonal column. As early as the fourth century in ancient Greece, the mathematician Pepos proposed that the beautiful shape of the honeycomb is the representative of the most efficient labor in nature. He conjectured that the hexagonal honeycomb that people see was built by bees using the least amount of beeswax. His conjecture was called the "Honeycomb Conjecture". Later facts and theories have proved that the honeycomb built by bees ...
