Özet:

 In this study, the effect of the gelcoat on the surface layer of the composite structures produced by vacuum infusion method on the mechanical properties and the effects of the lamination plan on the final product were investigated. Two different lamination plans were determined and gelcoat and non-gelcoat plates of these two different laminations were produced. In laminations, 300 grm2 discontinious mat and 300 grm² plain woven glass fiber reinforcements were used. Within the scope of the study, tensile, three-point bending and barcol hardness tests were carried out to investigate the mechanical properties. According to the test results, with the increase in the plain woven ratio in the structure, the bending strength is between 11.2-18.7; an increase of 11.7-16.6 was observed in the tensile strength. It has been determined that the use of gelcoat has a great effect on the mechanical properties. With the use of gelcoat, a decrease of up to 24.3 was observed in the flexural strength; A decrease of up to 17.8 was observed in tensile strength. Up to 5 higher barcol hardness values were obtained in laminations where the plain woven glass fiber layer is closer to the surface.

 Bu çalışmada vakum infüzyon yöntemi ile üretilen kompozit yapılarda yüzey katmanında kullanılan jelkotun mekanik özelliklere etkisi ve laminasyon planının nihai ürün üzerindeki etkileri araştırılmıştır. İki farklı laminasyon planı belirlenmiş ve bu iki farklı laminasyonun jelkotlu ve jelkotsuz plakaları üretilmiştir. Laminasyonlarda 300 grm2 keçe ve 300 grm2 bezayağı dokuma cam elyaf takviyeler kullanılmıştır. Çalışma kapsamında mekanik özellikleri araştırmak için çekme, üç nokta eğme ve barcol sertlik testleri yapılmıştır. Test sonuçlarına göre yapıda bez ayağı dokuma oranı artmasıyla birlikte eğme mukavemetinde 11,2-18,7 arasında; çekme mukavemetinde ise 11,7-16,6 arasında artış gözlemlenmiştir. Jelkot kullanımının mekanik özelliklere etkisinin büyük olduğu tespit edilmiştir. Jelkot kullanımı ile birlikte eğme mukavemetinde 24,3e kadar düşüş gözlemlenirken; çekme mukavemetinde 17,8e kadar düşüş gözlemlenmiştir. Bezayağı dokuma cam elyaf katmanının yüzeye daha yakın olduğu laminasyonlarda 5e kadar daha yüksek barcol sertlik değerleri elde edilmiştir.
