The mechanical properties of sandwich composites are more depended on the core material structure. Damage of the commercial honeycomb core materials are generally occurred as delamination the unit-cells of core material under mechanical or impact loads. In addition, the common feature of commercial core materials is their high-cost. Economic approach of the current researches are led the studies based on the principle of converting ordinary materials into advanced materials. Nowadays, the development of low-cost/high-performance products that serve to reduce environmental impact is an important requirement. In present study, a novel core material is developed for sandwich composites by using a special stitching design. The developed core structure is defined as ‘rhombus core’ which offers a lower cost/higher performance compared to commercial core materials. The compressive behavior of rhombus and commercial core structures are compared. Rhombus cores showed the highest compressive strength and retained their structural integrity after compressive load without any delamination/crushing at stitching regions.

Sandviç kompozitlerin mekanik özellikleri daha çok çekirdek malzeme yapısına bağlıdır. Ticari balpeteği çekirdek malzemelerde mekanik veya darbe yükü altında meydana gelen hasar genellikle, çekirdek birim hücrelerinin delaminasyonu ve ezilmesi olarak gerçekleşmektedir. Ayrıca, ticari çekirdek malzemelerin ortak özelliği, yüksek maliyetleridir. Güncel araştırmaların ekonomik yaklaşımı, sıradan malzemelerin ileri malzemelere dönüştürülmesi ilkesine dayalı çalışmalara yön vermektedir. Günümüzde çevresel etkiyi azaltmaya yönelik düşük maliyetli/yüksek performanslı ürünlerin geliştirilmesi önemli bir gereksinimdir. Bu çalışmada, özel bir dikiş tasarımı kullanılarak sandviç kompozitler için yeni bir çekirdek malzeme geliştirilmiştir. Geliştirilen çekirdek yapı, ‘rombus çekirdek’ olarak tanımlanmakta ve ticari çekirdek malzemelerine kıyasla daha düşük maliyet/daha yüksek performans sınmaktadır. Rombus ve ticari çekirdek yapıların basma davranışı karşılaştırılmıştır. Rombus çekirdek yapılar en yüksek basma dayanımını göstermiş ve hücre duvarlarını oluşturan dikiş bölgelerinde herhangi bir delaminasyon/ezilme olmaksızın basma yüküne maruz kaldıktan sonra yapısal bütünlüklerini korumuşlardır.
