Rüzgar Türbini Kanatlarında Kullanılan Yapıştırıcı Malzemelerin Değerlendirilmesi

Rüzgar türbinindeki FRP elemanlarının birleştirilmesinde yaygın olarak kullanılan yapıştırıcı bağların, çoğu ticari uçakta bulunan civatalı bağlantıların yerine geçmek için güçlü bir potansiyeli olduğu düşünülmektedir. Bu makalede, mekanik sistemlerde mafsal (bağlantı) oluşumu ve rüzgar türbini kanatlarının birleştirilmesi için kullanılabilecek yapıştırıcı malzemelerin farklı ailelerinin bütünsel değerlendirmesi için Bulanık Normalize edilmiş-Hamming (sinyal) aralığı ve İdeal Alternatif (FL2DIA) modelinin entegrasyonuna dayanan yeni bir yöntem önerilmiştir. Kırılma mekaniği temelli kriterlere göre değerlendirilen yapıştırıcı malzemelerde, en iyi alternatifi seçmek için uzman temelli görüş kullanır. Çalışmanın sonucu, Akrilik yapıştırıcı malzemenin (A3), rüzgar türbini kanadının birleştirilmesi ve ticari uçaklarda mafsal oluşumu için en yüksek potansiyele sahip olduğunu göstermektedir. Çalışma sonucu, yapıştırıcı malzemenin değerlendirilmesi için tanımlanan prosedür, FRP rüzgar türbini kanadının yapıştırılması için en iyi yapısal yapıştırıcının seçimine yol açmıştır. Ayrıca, aynı şart altında benzer mevcut yöntem (geleneksel bulanık TOPSIS modeli) ile tamamen karşılaştırılan çalışma, farklı alternatifleri sıralamak için önerilen yöntemi kullanmanın uygunluğu, rasyonalitesi ve fizibilitesini ortaya çıkarmıştır. Yapıştırıcı malzemenin sıralamasına odaklanan karşılaştırma sonucu, önerilen yöntemle tam uyumu göstermiştir.

Evaluation of Adhesive Materials Used in Wind Turbine Blades

Adhesives bonds which are used extensively in the joining of FRP elements in wind turbine are considered a strong potential to replace the bolted joints found in most commercial aircraft. In this paper, a new method which is based on the integration of a Fuzzy Normalized-Hamming distance and Ideal Alternative (FL2DIA) model is proposed for the holistic evaluation of the different families of adhesive materials, which can be used for the formation of joints in mechanical systems and for joining wind turbine blades. The adhesive materials which are evaluated with respect to the fracture mechanics-based criteria use expert-based opinion to select the best alternative. The result from the study shows that Acrylic adhesive material (A3) has the highest potential to be used for joining wind turbine blade and for the formation of joints in commercial aircraft. The study conclude that the procedure described for the evaluation of the adhesive material has led to the selection of the best structural adhesive to bond the FRP wind turbine blade. Also, it has revealed the suitability, rationality, and feasibility of using the proposed method for ranking the different alternatives as the result from the study have been fully compared with similar existing method (traditional fuzzy TOPSIS model) under the same condition. The comparison result which focuses on the ranking of the adhesive material shows total agreement with the proposed method.
