Bu çalışmada, el yatırması yöntemiyle 9 tabakadan üretilen ve matris içerisinde farklı oranlarda SiO₂ ve TiO₂ mikropartikülleri bulunan karbon fiber-epoksi kompozitlerin mekanik özellikleri incelenmiştir. Kompozitlerin katman yönelimleri farklı dizilimlerde karşılaştırılarak optimize edilmiş ve uygun katman yönelimi [0° / +45° / -45° / 90° / 0° / 90° / -45° / +45° / 0°] olarak belirlenmiştir. Deney kapsamında değerlendirilecek numuneler, ASTM-D638 ve ASTM E23 standartlarına uygun olarak üretilmiş ve çekme ile Charpy darbe testlerine tabi tutulmuştur. Kompozit plakalar, kütlece dört farklı mikropartikül oranıyla (0, %1, %2 ve %4) üretilmiştir. Çekme testlerinde, %1 SiO₂-TiO₂ mikropartikülleri içeren kompozitte, mikropartikül içermeyen kompozite kıyasla nihai çekme dayanımında %4,33'lük bir artış gözlemlenmiştir. Testlerden elde edilen çekme ve darbe dayanımı verileri karşılaştırılmış ve sunulmuştur. Bu araştırmanın amacı, SiO₂ ve TiO₂ kombinasyonundan oluşan mikropartiküller farklı oranlarda kompozite eklendiğinde, kompozit malzemenin mekanik özelliklerinde meydana gelen değişimlerin gözlemlenmesi ve araştırılmasıdır. Bu etkilerin araştırılmasında çekme ve Charpy darbe testleri kullanılmıştır.

In this study, the mechanical characteristics of carbon fiber-epoxy composites containing different ratios of SiO₂ and TiO₂ microparticles in their matrix, produced from nine sheets by hand lay-up, were investigated. The layer orientations of the composites were compared in different configurations and optimized, and the suitable ply sequence [0° / +45° / -45° / 90° / 0° / 90° / -45° / +45° / 0°] was determined. The specimens evaluated within the scope of the experiment were prepared in accordance with ASTM-D638 and ASTM E23 standards, and tensile and Charpy impact tests were performed. Composite plates were fabricated with four different microparticle ratios by mass (0, 1%, 2%, and 4%). In the tensile tests, the composite containing 1% SiO₂-TiO₂ microparticles was observed to exhibit a 4,33% increase in ultimate tensile strength compared to the composite without microparticles. Tensile strength and impact strength data obtained from the tests were compared and presented. The aim of this research was to investigate the effects of adding SiO₂ and TiO₂ microparticles in various ratios on the mechanical properties of the composites. Tensile and Charpy impact tests were used to evaluate these effects.
