Description

Technical Field

[0002] Resin prepreg honeycomb is a lightweight honeycomb, a layered composite material composed of panels and honeycomb core materials. It is widely used in rail transit, aerospace and other fields due to its optimal specific strength, specific stiffness, maximum fatigue resistance, smooth surface and other characteristics.

[0003] During the production, the resin prepreg honeycomb core is combined with the upper and lower layers of panels and bonded together to form a honeycomb panel. During the process, the composite material of the panel and the honeycomb core needs to be hot-pressed and shaped by a hot pressing mechanism. At present, the composite material is generally placed under a hot pressing plate and hot-pressed by pressing the hot pressing plate downward. Since only one composite material can be hot-pressed at a time, the efficiency is low. At the same time, the panel is a double layer, and only one side is hot-pressed by the heating plate, which can easily lead to uneven heating of the upper and lower surfaces. Utility Model Content
