Abstract
Seramik sağlık gereçlerinde kullanılan klozet kapakları büyük çoğunlukta üreformaldehit bazlı hammaddelerden üretilmektedir. Yenilikçi tasarımlar daha fonksiyonel, daha ince kapaklara doğru gitmektedir. Ancak üreformaldehit gerek işlenebilme zorluğu gerekse mukavemetin yeterli olmamasından dolayı günümüz ihtiyaçlarını karşılayacak özelliklerdeki kapak modellerinin tasarım ve üretimine olanak sağlayamaması, farklı özellikleri bir arada barındıran kompozit malzemelere olan talebi günden güne arttırmaktadır. Bu çalışmada üreformaldehit yerine uzun yıllardır otomotiv başta olmak üzere elektrik, inşaat, ev cihazları gibi sektörlerde yaygın kullanılan SMC (Sheet Moulding Compound) yöntemi ile üretilmiş kompozit malzemeler değerlendirilmiştir. İstenen ürün özelliklerini sağlayan uygun SMC kompozisyonlarının belirlenmesi konusunda çalışmalar yapılmıştır. Ayrıca Ansys yazılım programı kullanılarak klozet kapakları için maksimum deformasyon ve gerilme değerleri bulunmuştur. Bu sayede üreformaldehit ile yapılan klozet kapakları ile kıyaslandığında, daha yüksek darbe dayanımı (145 MPa), daha ince ürün kesiti (4 mm) elde edilmiştir.

Abstract
Toilet seat covers used in ceramic sanitary ware is currently produced from urea formaldehyde-based raw materials. Innovative designs are moving towards more functional; tinner covers. However, the demand for composite materials with different properties is increasing day by day, as urea formaldehyde cannot allow the design and production of cover models that meet today’s needs due to both the difficulty in processing and its insufficient strength. In this study, instead of urea-formaldehyde, composite materials were produced with SMC (Sheet Moulding Compound) method, which has been widely used in sectors such as electricity, construction, and household appliances and especially in automotive many years, were evaluated. Studies have been carried out to determine suitable SMC compositions that provide the desired product properties. In addition, maximum deformation and stress values of toilet seat covers were found in the Ansys software program. In this way, higher impact strength (145 MPa) and thinner product cross-section (4 mm) were obtained when compared to toilet seat covers made with urea-formaldehyde.
