複合材料雷射加工發展趨勢
Development Trend of Laser Processing of Carbon Fiber Reinforced Plastics
摘要
由於複合材料（Carbon Fiber Rein forced Plastics, CFRP）重量輕、強度大、可設計性好、耐衝擊及耐腐蝕等優勢，使其廣泛被應用於汽車、航空、航太、綠能等領域，且在使用上隨著時代進步、運動器材的輕量化、風力葉片發電效能的提升、交通運輸工具的節能需求與工業生產設備大型化需求…等，均使複合材料結構件朝向大型化與輕量化的趨勢。然而複材產業加工應用技術仍以傳統接觸式刀具加工為主，其中刀具嚴重的磨耗問題及加工參數沒有辦法有效調整的情況下，加工品質容易出現問題，使得廠商常面臨高成本、低良率的問題。近年來，雷射的興起帶來非接觸式加工的熱潮，亦同時為複合材料加工帶來新的發展。透過非接觸式雷射加工玻璃纖維複合材料，可避免接觸式鑽削加工對於材料之脫層影響達到降低粉塵之功效。而材料吸收率對於雷射加工的品質具有很關鍵的影響，針對玻璃纖維材料使用波長10640 nm是較為適合的波段，但其光路傳遞無法像光纖雷射般便捷，需另外加裝導光臂系統才可搭配機器手臂及CAD/CAM（Computer Aided Design/Computer Aided Manufacturing）路徑規劃，進行大尺寸三維切割應用，例如運動器材管件切割、車體殼件切割等應用。本文將針對複合材料雷射切割技術、技術發展趨勢進行介紹。

With the advantages of light weight, high strength, good designability, impact resistance and corrosion resistance, Carbon Fiber Reinforced Plastics (CFRP) is widely used in automotive, aviation, aerospace, green energy and other fields. With the progress of the times, the lightweight of sports equipment, the improvement of the power generation efficiency of wind blades, the energy-saving needs of transportation vehicles, and the need for large-scale industrial production equipment, etc., all make CFRP structure parts toward the trend of large-scale and lightweight. However, the processing of CFRP is still dominated by traditional contact tool processing. When the tool is seriously worn and the processing parameters cannot be adjusted effectively, the processing quality is prone to problems.In recent years, the rise of lasers has brought an upsurge in non-contact processing, and at the same time brought new developments in CFRP processing. Through non-contact laser processing of CFRP, the impact of drilling on the delamination of materials can be avoided, and reduce the effect of dust. The material absorptivity has a key influence on the quality of laser processing. For CFRP, the wavelength of 10640 nm is more suitable. However, its transmission is not as convenient as that of fiber lasers. The articulated arms can be used with robotic arms and CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) motionpath planning for large-scale 3D cutting applications, such as sports equipment pipe cutting, auto body cutting and the other applications. This article will introduce the CFRP laser cutting technology and technology development trend.
