Abstract

Bu çalışmada farklı oranlardaki nanopartikül takviyesinin fiber, matris ve boşluk hacim oranlarına etkisi incelenmiştir. Karbon fiber/epoksi nanokompozit plakalar vakum infüzyon yöntemi (VİY) ile üretilmiştir. Üretim öncesinde matris elemanı olan epoksi içerisine farklı oranlarda nanopartikül katılmıştır. Üretilen nanokompozitler standartlarda verilen ölçülerde hazırlandıktan sonra yakma testine tabi tutulmuştur. Nanopartikül katkısı arttıkça hem epoksinin viskozitesi hem de epoksi içerisinde nanopartikül kümelenmeleri artmıştır. Bunun sonucunda üretim esnasında epoksinin basınç altında vakumlanması ve fiberleri ıslatması zorlaşmıştır. Yakma testi sonucunda %5 nanopartikül katkısının boşluk hacim oranını %221 arttırdığı sonucuna ulaşılmıştır.
