| Abstract Scope |
Laminated fiber-reinforced polymer (FRP) composites are important materials with a wide range of applications due to their excellent specific stiffness and strength. The high degree of interfacial adhesion is a crucial factor required for effective stress transfer between the fibers and matrix, which has a significant effect on the overall mechanical properties and reliability of the composites.
Our research aims to research of plasma-enhanced fiber-matrix interfacial bonding leading to improved properties of aramid, glass, and flax reinforcing fabrics, the most frequently used in laminated FRP composites. Plasma treatment was realized by the various plasma sources, namely diffuse coplanar surface barrier discharge (DCSBD), commercial volume dielectric barrier discharge (VDBD), and curved DCSBD. The physicochemical surface properties, such as wettability, morphology, and chemical changes of the plasma-treated fabrics were determined by the Washburn method, Scanning electron microscopy, and X-ray photoelectron microscopy. The mechanical properties such as flexural properties and ballistic resistance were studied.
Plasma treatment of aramid, glass, and flax fabrics significantly increased their wettability, improved the surface chemical activity, and slightly increased the surface roughness, as well as improved their mechanical properties. |
