Abstract

Bu çalışmanın amacı, deniz suyunun nano-montmorillonit modifiyeli epoksi yapıştırıcı ile birleştirilmiş kompozit tek taraflı bindirme bağlantılarının performansına etkisinin incelenmesidir. Nano yapıştırıcıları hazırlamak için epoksi reçinesine ağırlıkça % 2 nano montmorillonit ilave edilmiştir. VARIM (Vakumlu Destekli Reçine İnfüzyon Metodu) ile üretilen kompozit numuneler ASTM D5868-01 standartına göre yapıştırılmış ve 6 ay süreyle deniz suyuna daldırılmıştır. Deniz suyuna daldırmanın sonucunda yapıştırma bağlantılarının performansında önemli ölçüde bir azalma gözlenmiştir. Bununla birlikte, ağırlıkça % 2 nano montmorillonit / epoksi yapıştırıcıların özellikleri, deniz suyuna daldırmadan sonrada daha iyi geldiği gözlenmiştir. Hasar yüzeylerinin mikroyapılarını incelemek için taramalı elektron mikroskopu (SEM) ve optik mikroskop kullanılmıştır.

Abstract

The objective of this study was to investigate of nano-montmorillonite modified epoxy composite single-lap bonded joints, after being exposed to seawater immersion in order to understand the effect of seawater environment on their performance. To prepare the nano adhesives, nano montmorillonite (2 wt %) was incorporated into epoxy resin. Composite bonded specimens which manufactured with VARIM (Vacuum Assisted Resin Infusion Method) were prepared accordance with ASTM D5868-01 and immersed in seawater for 6 months. As a result of seawater immersion, considerable reductions were observed in the adhesives performance. However, the properties of 2 wt% nano montmorillonite/epoxy adhesives were observed that the performance changed less after exposing to seawater. Scanning electron microscope (SEM) and optical microscope were used to investigate the microstructures of the damage surfaces.
