Bio and nano technologies are absent or incipient in papermaking industry and, concretely, in recycling and high-yield pulps sectors. In this sense, the present Thesis uses cellulose nanofibers (CNF), both in bulk and on ...
Composite structures play a crucial role in lightweight applications due to their exceptional mechanical performance and low density. However, their anisotropic behavior and susceptibility to uncertainties, such as ...
The reason for the writing of this doctoral thesis arises from the commitment adopted by COMEXI in order to put its products in the market making his products more sustainable and environmentally friendly. Is in this ...
To achieve a sand filter design that reduce its pressure loss, computational fluid dynamics (CFD) tecnique was used combined with laboratory tests in a scaled filter using different filter media. The CFD models allowed to ...
Nanocellulose is a sustainable nanomaterial with outstanding physico-mechanical properties, a fact that confers the nanomaterial a huge potential in sectors such as the papermaking, nanocomposites, aerogels for selective ...
The objective of the thesis is to provide scaling tool predicting the response of composite structures under out-of-plane loading by testing small coupons. This global objective cannot be achieved without understanding the ...
Carbon dioxide (CO2) is largely emitted in the ignition of fossil fuels for transport, electricity generation or other industrial processes. CO2 is an inorganic compound that exists naturally on Earth, but its concentration ...
Es desenvolupa una eina de disseny per l'anàlisi de la tolerància al dany en composites. L'eina pot predir el inici i la propagació de fisures interlaminars. També pot ser utilitzada per avaluar i planificar la necessitat ...
his doctoral thesis aims at developing and implementing a computational framework for performing virtual testing of composite structures using a High-Performance Computing (HPC) environment. In this sense, this thesis ...
La majoria de les fallades en elements estructurals són degudes a càrrega per fatiga. En conseqüència, la fatiga mecànica és un factor clau per al disseny d'elements mecànics. En el cas de materials compòsits laminats, el ...
This thesis investigates the impact response of novel laminates made with “thin-plies” as well as proposes a toughening method to improve their impact tolerance. To this purpose, we devised a wide experimental campaign ...
