Abstract

The invention discloses a preparation method of a high-strength lightweight composite honeycomb panel. The preparation method is characterized by comprising the following steps: selecting materials for the composite honeycomb panel, wherein the materials comprise an aramid paper honeycomb core material, a cured glass fiber prepreg panel and a high-pressure decorative laminated board; cutting the composite honeycomb panel into a set shape; performing adhesive-glue blade coating on an adhesive face of the materials for the composite honeycomb panel; stacking and adhering the high-pressure decorative laminated board, the cured glass fiber prepreg panel, the aramid paper honeycomb core material, the cured glass fiber prepreg panel and the high-pressure decorative laminated board from top to bottom or from bottom to top so as to obtain a crude slab of the composite honeycomb panel; performing hot pressing on the composite honeycomb panel in hot-pressing equipment, wherein the hot-pressing temperature is 55-65 DEG C, and the temperature and pressure maintaining time is 80-100 minutes; finally, obtaining the semi-finished composite honeycomb panel. According to the method disclosed by theinvention, the hot-pressing temperature is reduced, the temperature maintaining time is shortened, the various performance indexes of the aramid composite honeycomb panel are ensured, the energy consumption is reduced, and the energy is saved.

Description

technical field [0001] The invention relates to the technical field of composite board preparation, in particular to a method for preparing a high-strength and lightweight honeycomb composite board. Background technique [0002] At present, honeycomb composite materials are widely used in various industries, especially in aviation, railway and shipbuilding industries because of their high strength and light weight. The traditional honeycomb material is mainly aluminum honeycomb, but with the successful development of aramid honeycomb, compared with aluminum honeycomb, aramid honeycomb has the characteristics of high strength, and is lighter in weight and also has the insulation that aluminum honeycomb does not have. Thermal insulation and other characteristics make aramid honeycomb have a larger application field than aluminum honeycomb. Therefore, aramid honeycomb is gradually replacing the application of aluminum honeycomb in various industries. However, the existing prep...
