近年來風力發電蓬勃發展，風力發電的構件需求也日益增長，為了提升現場施工速度和成品的平整性，本研究主要針對大型纖維強化塑膠(Fiber Reinforced Plastics, FRP)風機導罩構件的平板面接合及轉角處接合的平整性探討。本研究使用真空輔助樹脂轉注成型(Vacuum Assisted Resin Transfer Molding, VARTM)來製作大型風機導罩構件，並選用Core Combination Mat LTNM600/P3/600（Core-Mat P3）纖維布來進行鋪設。Core-Mat P3為具有導流介質之厚織雙軸向纖維布，導流介質為蓬鬆纖維層，蓬鬆纖維本身具有一定的厚度，即可在纖維層數較低的情況之下達到厚度設計的要求，但是在VARTM施工過後，實驗結果發現Core-Mat P3的缺點為常於內凹轉角及外凸轉角產生局部大小不一的皺褶，於平面處也會有厚度不平整的情況發生，造成這些問題的主要原因為Core-Mat P3由3種不同的纖維編織方法所組合而成，這三種不同的編織方法皆有不同的孔隙，在VARTM製程中因為壓力和拉力使乾毯間產生纖維內部堆積及孔隙，而這些缺陷都會進一步造成樹脂堆積。
在鋪設纖維的情況之下，過於蓬鬆的纖維無法完全貼合，使內部產生纖維堆積和拉扯；於真空壓力之下，不同孔隙大小使每層纖維層有凹凸不平的情況，在這些因素之下會使成品厚度不均，在成品接合時會因為厚度不均導致需要更長的修整時間、構件漏水等問題，本研究為了降低皺褶誤差與不平整的狀況產生，在纖維鋪設上嘗試使用不同的纖維搭接方法、真空氣壓值的調整，而轉角處本研究提出了在轉角處局部增加玻璃纖維布(Mat)，並使用噴膠進行假固定。經本研究結果顯示最佳的實驗積層調整可將轉角厚度誤差控制在3%之間。

In recent years, wind power generation has developed vigorously, leading to an increasing demand for components in wind turbine construction. In order to enhance on-site construction efficiency and the surface smoothness of finished products, this study primarily focuses on the investigation of flat surface bonding and corner bonding smoothness of large-scale Fiber Reinforced Plastics (FRP) wind turbine nacelle components. Vacuum Assisted Resin Transfer Molding (VARTM) was employed in this research to fabricate the large-scale wind turbine nose cones, utilizing Core Combination Mat LTNM600/P3/600 (Core-Mat P3) fiber fabric for layup.
Core-Mat P3 is a thick-woven biaxial fiber fabric with flow-inducing media in between the layers. The flow-inducing media consists of loosely distributed fibers, which provides a certain thickness to meet design requirements even with fewer fiber layers. However, after VARTM construction, experimental results revealed that Core-Mat P3 exhibited drawbacks, such as uneven local wrinkles at internal concave and external convex corners, as well as uneven thickness on flat surfaces. These issues were primarily attributed to Core-Mat P3 being composed of three different fiber weaving methods, each contributing distinct porosity. During the VARTM process, pressure and tension cause fiber accumulation and voids between the dry layers, resulting in further resin buildup.
When laying the fibers, excessively loose fibers fail to fully adhere, leading to fiber accumulation and stretching within the material. Under vacuum pressure, the varying pore sizes contribute to uneven layers, leading to inconsistent thickness. These factors collectively result in longer finishing times, component leakage, and other issues during component assembly due to uneven thickness. In order to mitigate wrinkles and unevenness, this study attempted different fiber overlap methods and adjustments in vacuum pressure. For corner regions, the study proposed the localized addition of glass fiber cloth (Mat) and utilized spray adhesive for temporary fixation. The research findings indicate that optimal experimental layering adjustments can control corner thickness discrepancies within 3%.
