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
The present invention relates to the manufacture method of fiber reinforced composite dot matrix core board.
Background technique
The truss core structure is a kind of new structure that designs in order to satisfy engineering structure light and multifunction to require.Lattice material himself also is good compact heat exchanger except carrying.Simultaneously, if in the panel of truss core structure, bury the transistor network of transmitted power in advance underground, then can spend minimum energy part and actuate part dot matrix micro lever to realize the bending and the torsional deflection of macrostructure; If pre-buried heat pipe in panel and hole then can be realized the autonomous exchange of heat; If decentralized configuration power supply in the panel of structure and hole then can be braking, vibration isolation and even aircraft the energy is provided.Therefore, the truss core structure becomes current think the in the world the most promising advanced person of a new generation, lightweight, superpower tough multifunctional material.At present, relevant researcher has proposed the various topological structures of lattice material, its preparation scheme is for based on the net on the steel fiber weaving basis being lamination spot welding scheme, investment casting scheme and based on rolling on the micro-contact printing technical foundation-electroplate welding scheme, the material that is adopted is aluminium, steel etc., do not use composite material.Existing dot-matrix sandwich panel is shaped difficult, and uses material only to be confined to metallic material.
Summary of the invention
The present invention is in order to solve the existing dot-matrix sandwich panel difficulty that is shaped, and uses material just to be confined to the problem of metallic material, the invention provides a kind of manufacture method of fiber reinforced composite dot matrix core board, and the concrete technological scheme that addresses the above problem is as follows:
Fiber-reinforced composite dot-matrix sandwich panel of the present invention is made of fiber composite top plate, fiber composite lower panel and dot matrix, dot matrix is located between fiber composite top plate and the fiber composite lower panel, dot matrix is made of some fiber composite posts, the upper end of fiber composite post and fiber composite top plate are affixed, and the lower end of fiber composite post and fiber composite lower panel are affixed.
The step of manufacturing of fiber reinforced composite dot matrix core board of the present invention is as follows:
Step 1, (dry method) design cleaning mould are cleaned out the die surface that designs and produces, and are coated releasing agent;
Step 4, the fibre body that the step 3 laying is finished are placed on the cure under pressure of heating on the hydraulic press, and solidifying temperature is 150～180 ℃, temperature maintenance 2.5～3.5 hours, and solidifying pressure is 1～2Mpa, promptly makes fiber reinforced composite dot matrix core board.
The step of manufacturing of fiber reinforced composite dot matrix core board of the present invention is as follows:
Step 1, (wet method) design cleaning mould are cleaned out die surface, and are coated releasing agent;
Again the fleece-laying of rest layers is finished on step 4, the top plate after step 3 is sewed up and the lower panel;
Step 5, step 4 is laid the die cavity that the fibre body finish is put into a closure, the die cavity height is the height of dot-matrix sandwich panel, with the mould good seal;
Step 6, in the fibre body of step 5, inject body material, treat that body material soaks in top plate and lower panel surface and the hole fully;
Step 7, treat promptly to make fiber reinforced composite dot matrix core board by the matrix solidifying.
Body material adopts epoxy resin.
Fiber reinforced composite dot matrix core board mould-forming method of the present invention is compared with the conventional metals dot-matrix sandwich panel, be shaped easily, and material is selected face width.This plate has ultralight matter, high specific stiffness, high specific strength, designability is strong and satisfy the needs that multifunction requires.
