Çok duvarlı karbon nanotüp katkılı poliamit 6 polimerinin mekanik özelliklerinin incelenmesi

Bu çalışmada, poliamit 6 (PA6) polimerine çok duvarlı karbon nanotüp (ÇDKNT) takviye edilerek PA6/ÇDKNT nanokompozitleri üretilmiştir. Elde edilen nanokompozitlerde değişen ÇDKNT miktarının çekme, eğilme ve darbe dayanımlarına etkisi incelenmiştir. ÇDKNT nanotakviyelerinin PA6 matriks içerisindeki homojen dağılımlarının sağlanması için PA6/ÇDKNT karışımı çift vidalı ekstruderden geçirilmiştir. Elde edilen karışım enjeksiyonla kalıplama tekniği kullanılarak, çekme, darbe ve eğilme numunelerinin üretiminde kullanılmıştır. Çalışma sonucunda, ÇDKNT miktarının PA6 matriksinin mekanik özellikleri üzerinde önemli etkisi olduğu belirlenmiştir. Buna göre, artan ÇDKNT miktarına bağlı olarak PA6/ÇDKNT nanokompozitlerin çekme ve eğilme dayanımları ile elastisite modülleri sırasıyla %5.79, %16 ve %7.8 oranlarında artarken darbe dayanımı ve şekil değiştirme değerleri sırasıyla %11.2 ve %988 oranlarında azalmıştır.
