Abstract

This study examined the determination of theoretical buckling load of hybrid composite laminates with different hole diameters using the Taguchi-based fuzzy optimization method. In the Taguchi-based fuzzy method, the buckling parameters in the theoretical approach were used as input data, and the critical buckling load value was considered the output. Multiple Performance Characteristics Index (MPCI) was utilized for determining optimization results. Moreover, theoretical results verified by experimental and numerical approaches. In the experimental approach, the hybrid composite laminates (HCGFRE) manufactured by sequential sequencing of plain woven glass fiber reinforced epoxy (GFRE) and plain woven carbon fiber reinforced laminates (CFRE). Tests were carried out at a constant loading rate of 1 mm/min at room temperature. In numerical analysis, eigenvalue buckling was performed using Ansys finite element program. Composite laminates were formed utilizing Composite PrepPost (ACP) sub-module. Eventually, it was observed that using the Taguchi-based fuzzy method to determine the critical buckling load of hybrid composite laminates is consistent with both experimental and numerical approaches in terms of results

Özet

Bu çalışmada, farklı delik çaplarına sahip hibrit kompozit laminatların teorik burkulma yükünün Taguchi tabanlı bulanık optimizasyon yöntemi kullanılarak belirlenmesi incelenmiştir. Taguchi tabanlı bulanık yöntemde, teorik yaklaşımdaki burkulma parametreleri girdi verisi olarak kullanılmış ve kritik burkulma yükü değeri çıktı olarak alınmıştır. Optimizasyon sonuçlarını belirlemek için Çoklu Performans Karakteristikleri İndeksi (MPCI) kullanılmıştır. Ayrıca, teorik sonuçlar deneysel ve sayısal yaklaşımlarla doğrulanmıştır. Deneysel yaklaşımda, hibrit kompozit laminatlar (HCGFRE), düz dokuma cam elyaf takviyeli epoksi (GFRE) ve düz dokuma karbon elyaf takviyeli laminatların (CFRE) ardışık olarak sıralanmasıyla üretilmiştir. Testler, oda sıcaklığında 1 mm/dakika sabit yükleme hızında gerçekleştirilmiştir. Sayısal analizde, özdeğer burkulma analizi Ansys sonlu elemanlar programı kullanılarak gerçekleştirilmiştir. Kompozit laminatlar, Composite PrepPost (ACP) alt modülü kullanılarak oluşturulmuştur. Sonuç olarak, hibrit kompozit laminatların kritik burkulma yükünü belirlemek için Taguchi tabanlı bulanık yöntemin kullanılmasının, sonuçlar açısından hem deneysel hem de sayısal yaklaşımlarla tutarlı olduğu gözlemlenmiştir.
