The honeycomb core is a low-density honeycomb material used as a core material for a sandwich structure.
The honeycomb core material generally has a hexagonal structure similar to a natural honeycomb, which can withstand high pressure and tension, ensuring its stability and reliability during use. In addition, honeycomb core materials can also improve their durability through surface coatings and other technologies. Due to the special structure of the honeycomb core material, the material can be reused by separating and recycling the raw materials. This not only reduces waste emissions, but also reduces the risk of environmental pollution.
What does honeycomb core made of?
Honeycomb can be divided into aluminum honeycomb, paper core material, polystyrene foam honeycomb, polyurethane foam honeycomb, PVC foam honeycomb, PP foam honeycomb, PC foam honeycomb, aramid honeycomb, Carbon Fiber composite honeycomb, glass fiber composite honeycomb, wood honeycomb, stone honeycomb, fabric honeycomb, stainless steel honeycomb, titanium. zinc honeycomb, etc.
What's the advantages of Aramid honeycomb core?
Aramid honeycomb materials are lightweight, high-strength, high-modulus, and have strong structural stability. They also have advantages such as sound insulation, heat insulation, and flame retardant. They can be used as lightweight and high-strength structural materials (mainly as core materials) and applied in key fields such as aerospace, rail transportation, and national defense.
The aramid honeycomb core material has become an important weight-reducing material in the fields of aerospace and rail transportation due to its excellent performance. At the same time, combined with pre-impregnated materials, it occupies an important position in the field of wave absorption.
In recent years, carbon fiber composite honeycomb and fiberglass composite honeycomb have overcome technical difficulties and started mass production.
Based on the traditional aramid honeycomb core production process, CMAG Company continuously explores and improves the production process, solves many technical problems, forms unique technologies and processes, and collaborates with upstream and downstream to customize, develop, and apply materials and equipment. A variety of industry-leading aramid, carbon fiber and fiberglass honeycomb products have been widely used in many high-precision fields at home and abroad.
What is the procedures to produce honeycomb core?
The method of producing a cell includes multiple steps, which are specifically as follows:
① Adhesive application: Based on the required honeycomb hole size, apply adhesive at the appropriate position of the aramid paper using a adhesive roller printing machine.
② Stacking: Cut aramid paper according to the required size, stack multiple sheets of aramid paper in a staggered manner, heat and pressurize to solidify, and make honeycomb stacks.
③ Stretching: Stretch the honeycomb stacks to honeycomb block and when the hole size meets the process requirements, the honeycomb block will be heated and shaped in a high-temperature oven to make white honeycomb blocks.
④ Soaking: Place the white honeycomb into the phenolic resin, and soak, flip, air, weigh, and air in sequence. The larger the hole, the more immersion times it needs, and try to ensure that the immersion parameters for each time are the same.
⑤ Curing: Clean, dry, and heat the honeycomb blocks after immersion.
⑥ Slicing: The honeycomb blocks are cut into pieces to make honeycomb core material products.
The above is the basic production process of aramid honeycomb. It is important to note that process problems may occur in each process, which may affect the subsequent process and cause defects in the honeycomb. Therefore, in the production process, strict control of the quality of each process is required.
In order to improve the density uniformity and performance stability of aramid honeycomb, some optimization measures are also involved in the production process, such as controlling environmental temperature and humidity, improving lamination accuracy, reducing impurities in the adhesive solution, and optimizing the size of the adhesive roller printing groove.
