Bu çalışmada tersine
mühendislik uygulamalarında yaygın olarak kullanılan ve bilinmeyen
analizlerinde güçlü bir analiz metodu olan, Eş Odaklı Raman mikroskopisi
yöntemi kullanılarak türü bilinmeyen bir Polimerik kompozit malzemenin
moleküler yapısından yola çıkarak polimer türü ve dolgu malzemeleri
tanımlanmaya çalışılmıştır. İleri araştırmalarda kullanılan kemometrik
yöntemler ile yapısı analiz edilen kompozit malzemenin, yapısını oluşturan her
bir bileşiğin, kompozit yapısı içindeki miktarsal oranı araştırılmıştır.
Kompozit malzemenin kullanım alanı dışında hiçbir veriye sahip olunmadığı için
içeriğindeki malzemeler ile ilgili hiçbir yakınsama yapılmayarak sadece analizi
yapılan kompozitin mikroskop görüntüsü altında her bir farklı kısmından elde
edilen Raman spektrumları kütüphane taraması ile eşleştirilmiştir. Yapılan
eşleştirmelerde en yüksek eşleşme oranına sahip malzeme olduğu varsayılarak
analizler ve hesaplamalar bu doğrultuda devam ettirilmiştir. Eş Odaklı Raman
mikroskobu ile kompoziti oluşturan üç ana bileşik üzerine yoğunlaşılarak
malzeme yüzeyinde haritalandırma yapılmıştır. Kompoziti oluşturan üç ana
bileşenin sırası ile polipropilen (PP), silisyum karbür (SiC) ve karbon fiber
(KF) olduğu anlaşılmıştır. Bu üç bileşenin, kompozit içindeki hacimce oranları
20X optik büyütme altında, sırası ile %60, %26, ve %14 olarak hesaplanmıştır.
Eş Odaklı Raman mikroskopu tekniği kompozit malzemelerin içine katılan ve
kompozite artı özellik katan tüm malzemelerin tanımlanmasında kullanılabilecek
ileri bir enstrümantal analiz yöntemi olduğu görülmüştür.

 In this study, it has been tried to define polymer type and filler materials based on the molecular structure of an unknown type of Polymeric composite material by using the Confocal Raman Microscopy method which is a powerful method of analysis used in reverse engineering applications. The amount of the composites in the composite structure of the composite material, whose structure was analyzed by the chemometric methods used in advanced research, was investigated. Since there is no data other than the usage area of ​​the composite material, no convergence is made about the materials in its content and only the Raman spectra obtained from each different part of the composite under the microscope image of the analyzed composite were matched with the library survey. Assuming that the material with the highest match ratio was matched, the analyzes and calculations were continued in this direction. The Confocal Raman Microscope was focused on the three main compounds that were polypropylene (PP), silicon carbide (SiC) and carbon fiber (CF), mapped on the surface of the material. The ratios of these main components of the composite were calculated as 60%, 26%, and 14% under 20X optical magnification, respectively. Confocal Raman microscopy technique has been seen an advanced instrumental analysis method which can be used to identify all the materials that are incorporated into composite materials.
