Abstract

The invention discloses a stamping method and equipment for producing fiber-reinforced composite material preform. Existing fiber layup techniques can be used to produce 2D and simple 3D preforms, whereas for more complex geometries, such as automotive B-pillars, existing layup techniques cannot be applied. This method uses stamping technology to manufacture preforms with complex geometric shapes; preforms can be made into ultra-light and super-strong composite parts through autoclave, resin injection and other processes, which greatly reduces the production cost of parts and makes them suitable for civil use Products, such as car frames; this method can also be used in the stamping process of braided fabrics such as carbon fiber and glass fiber. This process simulates manual forming, giving uniform in-plane and out-of-plane support to the layer throughout the whole process, greatly reducing excessive lateral slippage, wrinkles and fiber breakage of fiber filaments during the stamping process, and improving production while ensuring product quality Efficiency, automated, digitized and unattended.

Description

technical field [0001] The invention relates to a stamping method and equipment for producing preformed fiber composite materials. Background technique [0002] High-performance carbon fiber composite materials have extremely high specific stiffness (5 times that of steel) and specific strength (8 times that of steel). It also has better fatigue properties and chemical resistance than ordinary steel. Therefore, high-performance composite materials are widely used in aerospace, high-end automobiles, wind energy, luxury yachts, tidal power generation, sporting goods and military industries. Composite materials are widely used as load-bearing parts in Formula 1 racing car, BMW i8 coupe, Airbus A380 passenger plane and fan blades; , also received high attention. [0003] Due to the complex and changing multi-scale structure of composite materials, it cannot be fully automated from raw material production to final industrial application. Many processes, long cycle time, and l...
