Manufacturing of structural components: The main structural components of aircraft, such as wings and fuselage, are often made of carbon fiber reinforced epoxy resin composite materials. For example, the Boeing 787 Dreamliner widely uses this material to manufacture the fuselage and wings, which not only reduces weight but also has higher strength and stiffness, thereby improving fuel efficiency and flight performance.
Manufacturing and maintenance of engine components: In engine manufacturing, epoxy resin can be used to manufacture or repair high-temperature components such as combustion chambers and turbine blades. It can withstand the high temperature and pressure generated during engine operation, ensuring the stability and reliability of its components.
Composite material preparation: A composite material formed by combining epoxy resin with reinforcing materials such as carbon fiber and glass fiber. In addition to being used for large structural components mentioned above, it is also used to manufacture aircraft tail fins, flaps, landing gear doors, radar covers, and spacecraft shells.
Adhesive and sealing: Epoxy resin has excellent adhesive properties and can be used as an adhesive to connect different materials such as metals, composite materials, plastics, etc. in aerospace structures, ensuring the integrity and stability of the structure. At the same time, it can also be used as a sealant to fill joints and gaps, preventing leakage and corrosion. For example, it is often used in sealing parts such as aircraft fuel systems and hydraulic systems.
Electronic packaging: Sensitive components in aerospace electronic equipment are usually encapsulated with epoxy resin, which can protect the components from harsh environments such as vibration, impact, humidity, high and low temperatures, and radiation, ensuring stable operation of electronic devices in complex space or flight environments.
Coatings and Protection: Epoxy resin based coatings can be used for surface protection of aerospace components, effectively preventing corrosion, wear, and erosion from atomic oxygen, ultraviolet radiation, and other factors in the space environment, and extending the service life of the components.
Tool and mold manufacturing: In the manufacturing process of aerospace components, epoxy resin can be used to manufacture tools and molds, which can help form complex shaped aerospace components and can be repeatedly used to improve production efficiency and component manufacturing accuracy.
Manufacturing of solar panels: Epoxy resin is used in the manufacturing of solar panels in spacecraft to ensure that the panels can operate stably in extreme environments such as high temperature, low temperature, and strong radiation, providing reliable power supply for spacecraft
