Description

Technical Field

[0001] This utility model relates to the field of aerospace composite material component manufacturing technology, and in particular to a composite material surface treatment device. Background Technology

[0002] Composite materials, as a strategic emerging material, combine advantages such as high specific strength, ease of design, corrosion resistance, fatigue resistance, high temperature resistance, and low density, and are widely used in the aerospace field. In mainstream international wide-body long-range passenger aircraft like the Boeing 787 and Airbus's 350 composite material surface treatment device, the amount used exceeds 50%. In my country's C919 narrow-body mainline passenger aircraft, the amount used is approximately 12%, effectively reducing the weight of the airframe structure, improving its fatigue resistance, and lowering fuel consumption.

[0003] Currently, the main joining methods for aerospace CFRP composite materials include mechanical joining, hybrid joining, and adhesive bonding. Mechanical joining typically uses fasteners such as rivets and bolts to connect different composite components. However, this requires creating through holes on the surface of the parts, disrupting the continuity of fibers in localized areas. Furthermore, mechanical joining easily leads to localized stress concentration, which can cause high-risk defects such as delamination at the hole edges under long-term alternating loads, and is also detrimental to weight reduction. Hybrid joining, often referred to as adhesive riveting, does not effectively avoid the disadvantages of mechanical joining and increases manufacturing costs. Adhesive bonding uses an adhesive film to bond composite components together. It effectively avoids problems such as hole creation, stress concentration, and weight increase. This joining method is ideal for the structural characteristics of composite materials. To achieve the required adhesive strength, the CFRP composite adhesive bonding surface usually needs surface treatment to eliminate factors that are detrimental to adhesive performance, such as low interface roughness, few surface functional groups, low surface energy, and high chemical inertness, effectively promoting good bonding between the adhesive interface and the adhesive.

[0004] With the continuous deepening of research on composite material surface treatment technology, the mainstream cutting-edge composite material surface treatment technologies with practical value include low-temperature plasma treatment technology, laser treatment technology, and laser and low-temperature plasma coupled treatment technology. However, different treatment methods are required for composite materials in different parts of the aircraft, which requires three treatment platforms, resulting in low utilization rate of the treatment platforms, low composite material treatment efficiency, and high investment costs.

[0005] Therefore, there is an urgent need for a composite material surface treatment device to solve the above-mentioned technical problems. Utility Model Content
