“…The permeability coefficients of a single layer of fiber reinforcement in all directions of the plane can be considered to be the same, but the actual composite products are often made of multiple layers of different fiber reinforcements stacked on top of each other, such as carbon fiber, glass fiber, Kevlar fiber, and so on. Therefore, in the vertical direction, the permeability of different fiber reinforcement or interlayer materials is obviously different [24,25]. When the product is thicker, the permeability in the vertical direction has an effect on the flow of resin during the mold filling process.…”

In this paper, an enhanced VARTM process is proposed and its pressure effect on resin infusion behavior and composite material performance is studied to reveal the control mechanism of the fiber volume fraction and void content. The molding is vacuumized during the resin injection stage while it is pressurized during the mold filling and curing stages via a VARTM pressure control system designed in this paper. Theoretical calculations and simulation methods are used to reveal the resin’s in-plane, transverse, and three-dimensional flow patterns in multi-layer media. For typical thin-walled components, the infiltration behavior of resin in isotropic porous media is studied, elucidating the control mechanisms of fiber volume fraction and void content. The experiments demonstrate that the enhanced VARTM process significantly improves mold filling efficiency and composite’s performance. Compared to the regular VARTM process, the panel thickness is reduced by 4% from 1.7 mm, the average tensile strength is increased by 7.3% to 760 MPa, the average flexural strength remains at approximately 720 MPa, porosity is decreased from 1.5% to below 1%, and the fiber volume fraction is increased from 55% to 62%.

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 gr/m2 keçe ve 300 gr/m2 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 %24,3’e kadar düşüş gözlemlenirken; çekme mukavemetinde %17,8’e kadar düşüş gözlemlenmiştir. Bezayağı dokuma cam elyaf katmanının yüzeye daha yakın olduğu laminasyonlarda %5’e kadar daha yüksek barcol sertlik değerleri elde edilmiştir.
