Fiber reinforced composite materials are nowadays used in several industrial applications that pursue structural weight reduction to reduce fuel consumption. The stiffness-to-weight and strength-to-weight ratios of composite ...
The overall purpose of this Ph.D. thesis is to contribute to the reliable design of composite structures subjected to fatigue-driven delamination. The aim is motivated by a wish to reduce the amount of experimental testing ...
In recent years, the use of composite materials in the aeronautic, automotive, marine construction, etc. has increased significantly. Hence, there is an increasing need for repair technologies on primary structural components, ...
There is a general trend towards rehabilitation and strengthening of existing reinforced concrete (RC) structures due to the costs associated with the replacement of the structural members and the environmental impact ...
In the recent years, significant interest on the production, characterization and application of cellulose nanofibers has brought out among scientific and technic authorities. This special attention mainly comes from their ...
NSM strengthening technique under the influence of temperature and relative humidity, in which the interaction between materials involved is analyzed, is studied in this PhD. Therefore, this work is aimed at contributing ...
Every year, the textile industry generates large amounts of cellulosic waste during the production and fabrication stages. This waste is made up of fibers, with lengths are less than 10 mm that prevent its reintroduction ...
The present PhD work has been done within the research topics of the Laboratory of Paper Engineering and Polymer Materials (LEPAMAP) at the University of Girona. Composite materials from high yield corn biomass fibers ...
In the last decades, the use of laminated composites, such as Carbon Fiber Reinforce Polymer has increased in many industrial sectors. Different failure mechanisms different damage mechanism can appear in laminated ...
The thin-tile vault is a structural system widely used in the Mediterranean area. The most spectacular development took place through modernist-style buildings designed by architects such as Antonio Gaudí o Luís Domènech ...
Aquesta tesi doctoral i tot el treball experimental s’ha realitzat dintre les línies de treball del grup de recerca, Laboratori d’Enginyeria Paperera i Materials Polímers (LEPAMAP) de l’Escola Politècnica Superior de la ...
Historically, the manufacture of advanced composite parts has been characterised by low-volume production, but is increasingly moving towards mass production. This new scenario, where competitiveness is on the rise, requires ...
Transport industry, especially automotive, is one of the most pollutant in the world. Current environmental concerns demand original equipment manufacturers (OEM’s) to reduce the amount of emissions released by their ...
Despite the weight savings, composite materials are vulnerable to impact loads mainly due to the alarming reduction in the compression after impact strength (CAI). This thesis exploits the potential of laminate designs ...
Nowadays the problem of climate change on planet Earth has aggravated, it has become extremely important to find solutions that considerably reduce or even eliminate its causes. Among the set of solutions that have been ...
The main goal of this thesis is the production and characterization of composites materials from a bio-based polyamide and natural fibres which could be more sustainable alternative to glass fibre reinforced polypropylene. ...
The rate-dependent behaviour of the interlaminar fracture toughness of fibre reinforced composites has been a matter of research during the last decades. However, the results obtained so far are not conclusive and further ...
In this thesis, a micromechanical model for predicting the tensile failure process in hybrid and non-hybrid unidirectional composite materials under fibre tensile loading is developed. Derived from this, the influence that ...
As a renewable alternative to petroleum-based materials, wood or plant-based materials offer a greater prospect in the transition towards sustainable replacements. Native to wood, cellulose nanofibers (CNF) form the major ...
In order to reduce mismatches between real and expected consumption, this thesis explores the use of PCA (Principal Component Analysis) as a modelling tool for buildings. PCA is a statistical technique that allows complex ...
