Abstract

Vinil ester reçineleri, partikül ve fiber takviyeli kompozitlerde matris malzemeleri olarak yaygın olarak kullanılmaktadır. Günümüzde polimer matrisli kompozitlerin mekanik özelliklerini artırmak için mikron boyutlu mikro yapılarda da partiküller tercih edilmektedir. Bu çalışmada 1-3 mikron boyutlarında alüminyum oksit partikülleri ile güçlendirilmiş vinil ester matrisli kompozitler üretilmiştir. Hazırlanan numunelerin çekme, 3 noktada eğilme, sertlik, darbe ve aşınma özellikleri gibi mekanik özellikleri incelenmiştir. Numune üretiminde teflon kalıp tercih edilmiştir. Reaksiyonda başlatıcı olarak %50 aktif metil etil keton peroksit ve hızlandırıcı olarak %6 kobalt naftalat kullanılmıştır. Vinil ester reçinesine ağırlıkça %0.5, 1, 1.5 ve 2 oranlarında alüminyum oksit ilave edildi. Partiküllerin karışım içinde dağılması ve aglomerasyonun önlenmesi için partikül miktarının 5 katı MEG (mono etilen glikol) ilave edilmiş ve formülasyon ultrasonik mikserde 30 dakika karıştırılmıştır. %1,5 Al2O3 takviyeli kompozit malzemelerde çekme, % uzama, darbe, sertlik ve aşınma özellikleri iyileştirildi. Eğilme mukavemetinde bir azalma gözlendi.

Effect of Al2O3 Particles on Mechanical Properties of Vinylester Composite Material

Abstract

Vinyl ester resins are widely used as matrix materials in particle and fiber reinforced composites. Nowadays, particles are also preferred in micron-sized microstructures to increase the mechanical properties of polymer matrix composites. In this work, vinyl ester matrix composites reinforced with aluminum oxide particles of 1-3 micron dimensions were produced. Mechanical properties such as tensile, 3 point bending, hardness, impact and wear properties of specimens prepared were investigated. Teflon mold was preferred to production of samples. In the reaction 50% active methyl ethyl ketone peroxide as initiator and 6% cobalt naphthalate as accelerator were used. Aluminum oxide was added to the vinyl ester resin at 0.5, 1, 1.5 and 2 wt% ratios. In order to disperse the particles in the mixture and prevent agglomeration, MEG (mono ethylene glycol) was added 5 times the amount of particles and the formulation was mixed in an ultrasonic mixer for 30 minutes. Tensile, % elongation, impact, hardness and wear properties were improved in 1.5% Al2O3 reinforced composite materials. A decrease in flexural strength was observed.
