The high production cost caused by a large number of manual operations
For large passenger aircraft, the physical characteristics of the structure will limit the use of the structure: because high-altitude flight will cause temperature fluctuations, condensed water will be generated in the honeycomb pores, In severe cold weather, the condensed water will freeze and expand to damage the material. Today this process has almost dominated the entire helicopter and wing aircraft interior industry. The foamed sandwich structure can be injection molded in various shapes on the injection molding machine to form various components 5.
The thermoplastic matrix can make the carbon fiber reinforced plastic foam composite material easier to weld with other components. In addition, the thermoplastic core foam plastic Composite materials have the following obvious advantages: 1. Especially in production, if glass fiber can be used to replace expensive carbon fiber, it will produce great benefits. 501 Core material foam, PMI foam, high temperature resistant foam The difference between PMI foam rubber and plastic foam What is the foam in the middle of the color steel house composite board. So far, the main use of high-cost processes is to use carbon fiber reinforced coatings and epoxy The sandwich structure of resin prepreg is attached to the aramid/phenol honeycomb core.
Because the helicopter flying height is lower than the wing aircraft, the honeycomb shape The sandwich structure can also be used for its supporting structure and coating. Moreover, the high production cost caused by a large number of manual operations and the high investment cost of the autoclave hinder the expansion of the application range of the traditional honeycomb structure. Compared with the honeycomb sandwich sandwich, no condensation water will be generated in the foam sandwich.ufeffNew core material foam plastics'>Core material foam plastic composite material structure: For the aerospace industry, the sandwich structure has excellent lightweight characteristics. The use of foam and matrix materials can realize the recycling of components and the reuse of carbon fiber.
Foam insulation and noise reduction performance Fortunately, because the multi-layer structure has great freedom of deformation in the thermoforming process, it may also be used in the automotive field, such as the front wall of the car compartment, the door Wholesale China CASCELL® IH Suppliers mezzanine or the seat. The corresponding thermal technology can be used according to the coating material The sandwich is bonded to the coating. In addition, the walls and ceilings of tourist cars are also It can be produced with a reinforced foam ier core multilayer structure. The fiber bundles and fiber pins coecting the foam and the sandwich coating can improve the compression resistance and shear resistance of the sandwich component
