Gama Işımasının Kolza Takviyeli Polipropilen Kompozit Malzemenin Mekanik Özellikleri Üzerindeki Etkisi

Bu araştırmada, kurutulmuş ve toz haline getirilmiş kolza bitkisi takviyeli polipropilen matrisli kompozit malzemenin, çekme, üç nokta eğilme ve Izod darbe mukavemetleri gibi mekanik özellikleri deneysel olarak incelenmiştir. Öncelikle matris malzemesi polipropilen olan ve ağırlıkça %5, %10 ve %20 oranında kolza içeren numuneler ekstrüzyon ve plastik enjeksiyon teknikleri kullanılarak üretilmiştir. Üretilen malzemelerin bir kısmı gama ışımasına tabi tutularak matris ve dolgu malzemesi arasındaki fiziksel bağlanma mekanizması güçlendirilmeye çalışılmıştır. Bu doğrultuda ışıma öncesi ve ışıma sonrası numunelerin mekanik özelliklerindeki değişimler araştırıldı. Yapılan testler sonucunda, çekme ve Izod darbe mukavemetleri, takviye olarak kullanılan kolza miktarının artması ile düştüğü, eğilme mukavemetinin ise arttığı gözlenmiştir. Gama ışımasına maruz bırakılan numunelerin çekme, eğilme ve Izod darbe mukavemetlerinde gama ışımasına maruz bırakılmamış numunelere göre artış meydana geldiği tespit edildi.

Effect of Gamma Radiation on Mechanical Properties of Rape Reinforced Polypropylene Composite Material

In this research, the mechanical properties of the dried and powdered rape reinforced polypropylene matrix composite material such as tensile, three-point bending and Izod impact strengths were experimentally investigated. Initially, samples whose matrix material was polypropylene and containing 5%, 10% and 20% by weight rape were produced using extrusion and plastic injection techniques. Some of the samples produced were exposed to gamma irradiation to strengthen the physical bonding mechanism between the matrix and the filling material. In this direction, the changes in the mechanical properties of the samples before and after gamma irradiation were investigated. As a result of the tests, it was observed that the tensile and Izod impact strengths decreased with the increase in the amount of rape used as reinforcement, while the bending strength increased slightly. It was determined that the tensile, bending and Izod impact strengths of the samples exposed to gamma irradiation increased compared to the samples that were not exposed to gamma irradiation.
