[0002] Drying is a crucial step in composite material production, and uniform drying is essential for the molding and quality of composite materials. The outer shell of the composite material drying oven is typically made of thin steel plate with a painted surface, while the working chamber is made of high-quality structural steel plate. The space between the outer shell and the working chamber is filled with aluminum silicate fiber.

[0003] In the existing technology, when using a special oven for composite materials, the preforms of the composite materials are usually loaded into a placement tray, then multiple placement trays are placed on a drying rack, the drying rack is pushed into the oven cavity, the oven door is closed and the oven is started to dry, thereby achieving the heating and curing of the preforms of the composite materials. After drying, the preforms are taken out one by one from the placement trays on the drying rack.
