Polyester Bağlayıcılı Kompozitlerin Mekanik Özellikleri

Bu çalışmada bağlayıcı olarak polyester, agrega olarak ponza ve katkı malzemesi olarak uçucu kül kullanılarak polyester bağlayıcılı polimer kompozitler üretilmiştir. Bağlayıcı malzeme olarak çimento yerine polyester kullanılması ile polyester esaslı çimentosuz kompozitler üretilmiştir. 40×40×160 mm ebatlarında prizmatik numuneler üretilerek kompozitlerin basınç ve eğilme dayanımları test edilmiştir. EN 196-1'e göre maksimum basınç ve eğilme dayanımları sırasıyla 45,69 MPa ve 8,49 MPa elde edilmiştir. Kontrol numuneye göre basınç ve eğilme dayanımları sırasıyla %32,2 ve %27,9 oranında artmıştır.

Mechanical Properties of Polyester Based Composites

In this study, polyester-based polymer composites were produced by using polyester as binder, pumice as aggregate and fly ash as additive material. Polyester-based composites were produced by using polyester instead of cement as binder material. The compressive and flexural strengths of the composites were tested by using prismatic samples of 40×40×160 mm. The maximum compressive and flexural strengths for EN 196-1 were 45.69 MPa and 8.49 MPa, respectively. Compressive and flexural strengths increased by 32.2% and 27.9%, respectively, compared to the control sample.
