Although films of microfibrillated cellulose (MFC) have good oxygen barrier properties due to its fine network structure, properties strongly deteriorate after absorption of water. In this work, a new approach has been followed for actively tuning the water resistance of a MFC fiber network by the inclusion of dispersed organic nanoparticles with encapsulated plant wax. The modified pulp suspen...

The common approach for simulating the evolution of fiber orientation during flow in concentrated suspensions is to use an empirically modified form of Jeffery’s equation referred to as the Folgar-Tucker (F-T) model. Direct measurements of fiber orientation were performed in the startup of shear flow for a 30 wt % short glass fiber-filled polybutylene terephthalate (PBT-30); a matrix that behav...

Reflectance acquired with a multimode optical fiber probe can be related to properties of an investigated turbid medium by utilizing light propagation model. During this step, calibration the model is required, as modeled reflectance normalized energy source fiber, while experimentally reflective standard. Since currently established methods based on liquid and solid phantoms suffer from drawba...

Anisotropic fiber-reinforced composites are used in lightweight construction, which is of great industrial relevance. During mold filling fiber suspensions, the microstructural evolution local arrangement and orientation distribution determined by velocity gradient. Based on Folgar–Tucker equation, describes second-order tensor terms gradient, present study addresses selected states deformation...
