Karbon Fiber/Epoksi Nanokompozit Plakalarda Nanopartikül Katkısının Fiber, Matris ve Boşluk Hacim Oranlarına Etkisi

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

Effect of Nanoparticles on Carbon Fiber/Epoxy Nanocomposite Laminates Fiber, Matris and Void Volume Fraction

In this paper, the effect of nanoparticles with different fractions on fiber, matrix and void volume fraction was investigated. Vacuum assisted resin transfer molding (VARTM) method was used to manufacture the carbon fiber/epoxy nanocomposite laminates. Before manufacturing, nanoparticles were added to epoxy with different fractions. Manufactured nanocomposites were applied to burning test after they cut into the size referred in standards. When fraction of nanoparticles increased, both the viscosity of epoxy and agglomeration of nanoparticles in epoxy increased. As a result, vacuuming of epoxy under pressure and wetting the fibers get hard while manufacturing. After burning test, it was found that adding 5% nanoparticles would increase void volume fraction by %221
