Abstract

The invention is a lattice sandwich plate made of reinforced composite fiber material and a manufacture method of the sandwich plate, and relates to a lattice sandwich plate and a manufacture method of the sandwich plate. The invention settles the problem that a prior lattice sandwich plate is difficult to be molded and materials used are limited to metal materials. A lattice of the invention is arranged between an upper fiber composite panel (1) and a lower fiber composite panel (3), and consists of a plurality of fiber composite columns (2). The upper ends of the fiber composite columns (2) are connected with the upper fiber composite panel (1) in a fixing way, while the lower ends of the fiber composite columns (2) is connected with the lower fiber composite panel (3) in a fixing way. The manufacture method is as follows: 1. a cleaning mould is designed and a demoulding agent is applied on the mould; 2. a pre-immersed material is cut into the designed size and filed into a pole, which is put into a mould hole; 3. the upper panel and the lower panel are laid; (4) solidification by heating and pressurizing is done, and the reinforced composite fiber material lattice sandwich plate is made. Compared with a traditional metal lattice sandwich plate, the reinforced composite fiber material lattice sandwich plate of the invention is provided with the higher intensity and rigidity, and can be designed easily.

Description

technical field [0001] The invention relates to a fiber-reinforced composite lattice sandwich panel and a manufacturing method thereof. Background technique [0002] The lattice sandwich structure is a new type of structure designed to meet the requirements of lightweight and multi-functional engineering structures. In addition to being load-bearing, the lattice material itself is an excellent compact heat exchanger. At the same time, if the transistor network for transmitting power is pre-buried in the panel of the lattice sandwich structure, it can spend a very small amount of energy to locally actuate some of the microrods of the lattice to realize the bending and torsional deformation of the macrostructure; if the panel and the hole If the heat pipe is embedded inside, the heat can be exchanged autonomously; if the power supply is distributed in the panels and holes of the structure, it can provide energy for braking, vibration isolation and even aircraft. Therefore, t...
