Gelişmiş Eğrisel Fiberli Değişken Rijitlikli Dokunmuş Kumaşlar

Bu çalışmada eğrisel gelişmiş ipliklere sahip değişken rijitlikli dokuma kumaşların üretimi için yeni bir yöntem sunulmuştur. Ölçeklenebilir bir konsept tasarım tanıtılmıştır. Prototip dokuma tezgahı ile değişken rijitlikli kumaşlar dokunmuştur. Dokuma işlemi ve dokunan kumaşlar incelenmiştir. Kumaşlarda farklı davranışlar gösteren iki ayrı bölgenin olduğu gözlenmiştir. Belirlenen iki bölgeye dayanarak, dokuma kumaşın eğimli iplikleri basitleştirilmiş ve üç boyutlu birim yapı olarak modellenmiştir. Eğri ipliklerin geometri değişimi ve dokuma kumaşların rijitlik değişimi, geliştirilen model kullanılarak bu iki farklı bölge için tartışılmıştır.

Variable Stiffness Woven Fabrics with Curved Advanced Fibers

A novel method for production of variable stiffness woven fabrics with curved advanced fibers is presented. A scalable concept design is introduced. Several variable stiffness fabrics are woven by the prototype loom. The weaving process and woven fabrics are examined. Two distinct regions of the fabric which are showing different behaviors are observed. Based on the two regions identified the curved fibers of the woven fabric are simplified and modeled as a three-dimensional unit mesh. Geometry variation of the curved fibers and stiffness variation of the woven fabrics are discussed for these two distinct regions by using the developed model.
