The aim of this thesis is to assess the feasibility of integrating nanoparticles into glass fiber (GF) reinforced isotactic polypropylene (iPP) composites via existing thermoplastic processing routes, and to investigate whether this results in significant ...
The potential of pulp fiberreinforced thermoplastics is currently not fully explored in composites. One of the main reasons is that pulp fibers are extracted for the use in papermaking and are thus not optimized for use as reinforcements in thermoplastics ...
Electrical resistance in carbon-fiber reinforced polymers has been shown experimentally to be a sensitive measure of internal damage. To quantify the dependence of electrical resistance on mechanical fiber damage at the micromechanical level, a numerical e ...
Commercially available graphite and ceramic fibers exhibit statistical strength distributions having separate Weibull moduli rho' for the scaling of strength versus fiber length and rho for the distribution of strengths across a collection of fibers at fix ...
Mechanical and fracture behaviors of wood are defined by the morphology and mechanical properties of wood fibers and their bonding medium. Parallel orientation of wood fibers makes them the most influential microstructural elements from the mechanical poin ...
The present study investigates the origin of voids in sheet molding compounds (SMCs) sheets and their transport during the manufacturing steps. Paste mixing, impregnation, thickening, and molding have been performed with five different SMC sheets, one with ...
The sol-gel technology offers highly interesting prospects for fiber fabrication. The main advantage is the possibility to incorporate any dopants and co-dopants soluble in a suitable solvent. Generally, these dopants are homogeneously dissolved in the mat ...
Unsaturated Polyester (UP) resins are extensively used as a matrix for the production of composites due to their low cost and versatility. Their significant polymerization shrinkage has however a negative impact on the dimensional stability of the molded p ...
Stress changes in hydrogenated phosphorous-doped fibers after Bragg grating inscription have been measured. Fibers with three different drawing tensions have been investigated. The core stress was found to increase independently of the initial stress state ...
The present work is aimed at assessing the feasibility of integrating thermoplastic polypropylene nanocomposite matrices into conventional fiber-reinforced composites based on hybrid textiles that incorporate both the matrix and glass-fiber yarns, in order ...
