Abstract

Bu çalışmada, silan kaplı SiO2 nanoparçacıkları cam elyaf takviyeli polimer (ETP) kompozitler için ikincil takviye olarak kullanılmış ve geliştirilen kompozitlerin mikrosertlik değerleri araştırılmıştır. Nanopartiküller polimer epoksi içinde sırasıyla ağırlıkça %1.5 ve %3 oranlarında karıştırılmıştır. KH550 ve KH570 olmak üzere iki farklı silan tipi değerlendirilmiştir. SiO2 nanoparçacıklarının düzgün dağılabilirliğini elde etmek için epoksi reçine ve nanopartiküller, ultrasonik homojenizasyona tabi tutuldu. Daha sonra matris, 100:25 ağırlık oranında uygun bir sertleştirici ile hazırlanmıştır. Güçlendirilmiş polimer matris, dokuma cam elyaf kumaşlarla (birincil takviye elemanı) takviye edilmiştir. Silan kaplı nano SiO2 dolgulu cam ETP kompozitleri üretmek için vakum torbası yöntemi uygulanmıştır. Vickers sertlik değerlerini belirlemek için dijital mikrosertlik test cihazı kullanılmıştır. Saf cam/epoksi kompozit 20.69 HV sertlik ile sonuçlanırken, maksimum sertlik değeri 36.56 HV olarak kaydedilmiş ve ağırlıkça %3 KH550-SiO2 dolgulu cam/epoksi ile elde edilmiştir. Silan kaplı SiO2 nanopartikülerinin dahil edilmesi, yaklaşık olarak %28'den %77'ye kadar çarpıcı iyileştirmeler sağlamıştır. Ayrıca optik mikroskop ile mikroyapı incelemesi de yapılmış olup görüntüler test sonuçlarını açıklamaya yardımcı olmuştur. Böylece, çalışmanın bulguları, silan kaplı nano SiO2 dolgunun, cam/epoksi kompozit uygulamaları için yüksek sertlik ve daha iyi aşınma direncinin istendiği durumlarda ikincil takviye olarak kullanılabileceğini göstermiştir.

Effect of Silane-Coated SiO2 Nanoparticles on the Hardness Values of Glass FRP Composites

Abstract

In this study, silane-coated SiO2 nanoparticles (as-received) were used as secondary reinforcement for glass fiber-reinforced polymer (FRP) composites, and the microhardness values of the developed composites were investigated. The nanoparticles were dispersed within the polymer epoxy at 1.5 wt.% and 3 wt.% ratios, respectively. Two different types of silane coating were used that were KH550 and KH570. The mixture of the epoxy resin and nanoparticles were subjected to ultrasonic homogenization to achieve a fine dispersibility of the SiO2 nanoparticles. Then the matrix was prepared with a suitable hardener at a weight ratio of 100:25. The strengthened polymer matrix was reinforced by woven glass fiber fabrics (primary reinforcing element). The vacuum bag method was applied to produce silane-coated nano SiO2 filled glass FRP composites. A digital microhardness testing device was used to determine the Vickers hardness values. While the pure glass/epoxy composite has resulted in a hardness of 20.69 HV, the maximum hardness value was recorded as 36.56 HV and it was obtained with 3 wt.% KH550-SiO2 filled glass/epoxy. The incorporation of silane-coated SiO2 nanoparticles has provided dramatic enhancements, approximately from 28% to 77%. The microscopic examination was also conducted via an optical microscope and the images were found helpful to explain the test results. Therefore, the findings of this study have shown that silane-coated nano SiO2 filler can be used as secondary reinforcement where high hardness and better wear resistance are desired for glass/epoxy composite applications.
