-
Forming networks: forming technologies and processes, hydrodynamics of fibre suspensions, fibre organization in sheet structure. Paper architecture: 2D organization, 3D organization, mass variations. Consolidation: hydrogen bonding in lingo-cellulosic materials, the fibre bond joint, water removal and development of physical properties. Mechanical properties: elastic deformations and stiffness, failure phenomena, rheology. Interaction properties: gas and liquid transport, hydro-expansion, optics. Paper and board surfaces: surface properties, surface modification, functional surfaces. Laboratory exercise: demonstration of important and interest phenomena. Practice measuring certain physical properties. Learn good measurement practices, data handling, reporting and analyzing results. The course aims to give students an in-depth understanding of random fibre networks in relation to forming process, raw materials and finished products.
