Abstract
Bu çalışmanın amacı, üç farklı katkı maddesinin silikona karıştırılarak silikon ve karbon fiber demetinin arayüzey kayma mukavemetinin nasıl değiştirdiğinin araştırılmasıdır. Son yıllarda polimer matrisli kompozitlerin kullanımı savunma, havacılık, spor gibi alanlarda belirli bir şekilde arttığından, bu malzemelerin özelliklerini anlamak ve geliştirmek ilgi çeker hale gelmiştir. Bu çalışma silikon matrisin davranışına odaklanmıştır. Silikonun viskozitesi diğer birçok reçineden daha yüksek olduğu için, ıslatma yeteneği, takviye edici kumaşların fiberlerinin arasına sızmak için yeterli değildir. Viskoziteyi düşürmek için çeşitli katkı maddeleri kullanılabilirken, bu katkı maddelerinin fiber-matris ara yüzeyinin kayma mukavemeti üzerindeki etkileri iyi bilinmemektedir. Fiber çekme testi, katkı maddesinin değiştirilmesiyle görünür ara yüzey kayma mukavemetinin nasıl değiştiğini görmek için tasarlanmıştır.

Abstract
The aim of this study was to investigate how
interface shear strength of silicone and carbon fiber tow changes by mixing
three different types of additives into silicone. As the interest on polymer
matrix composites has been rising in last decades in a certain manner in many
fields like defense, aerospace and sports, understanding and improving the
characteristics of these materials arouses interest. This work focused on the
behavior of silicone matrix. As the silicone’s viscosity is higher than many
other resins, it’s wetting ability is not enough to penetrate through the tows
of reinforcing fabrics. Various additives can be utilized to decrease the
viscosity whereas the effects of these additives on the fiber-matrix interface
shear strength are not well-known. Fiber pull-out testing was designed to see
how the apparent interfacial shear strength changes via changing the additive.
