Bu amaçla, bilgisayar kontrollü laboratuvar ölçekli Reçine Transfer Kalıplama (RTM) prosesi kurulmuştur. Ayrıca, tam kapalı, vakum destekli ve ısı kontrollü olarak tasarlanan RTM kalıbının alt ve üst yüzeylerinde parlatılmış paslanmaz çelik saclar kullanılarak iki yüzü düzgün kompozit levhalar üretilmiştir. Çalışmada RTM’ye uygun Polipol-336 polyester reçinesi kullanılmıştır. Kompozit levha imalatı için 800-500-300-200 g/m² 'lik iki-yönlü cam-dokumalar arasına 450-225 g/m² 'lik cam-keçeler yerleştirilmiştir. RTM prosesi sonunda kalıptan %38,1 - %48,0 fiber hacimli, 6-15 tabakalık farklı kombinasyonlarda ve yaklaşık 3 mm kalınlığında kompozit levhalar elde edilmiştir. Bu kompozit levhaların çekme ve eğilme mukavemeti gibi temel mekanik özellikleri test edilmiştir. Deneyler sonucunda, özellikle depolama tankları, deniz araçları ve yapı endüstrisi gibi sektörlerde kullanılan büyük ölçekli tabakalı kompozit levhalarda cam-dokumalar arasına cam-keçe takviyesinin mekanik anizotropi üzerinde olumlu etkisi olduğu tespit edilmiştir. Ayrıca maliyet açısından da değerlendirme yapılmış ve optimum kompozit levha maliyeti için önerilerde bulunulmuştur.
