“…Other key advantages of thermoplastic composites include the potential of fast in situ out-of-autoclave processing, by applying pressure and heat in one step, and the potential for automation with significant decrease of work time and costs [ 4 , 5 ]. For these reasons, fiber-reinforced thermoplastic composites are continuously replacing traditional materials like metals and wood in many applications [ 6 , 7 ]. On the other hand, one of the main problem of thermoplastic composites is the high viscosity of the molten matrix, which leads to a difficult impregnation of the fiber bundle.…”

In this work, the potential of preformed thermoplastic matrix composite tapes for the manufacturing of composite pipes by filament winding assisted by in situ ultrasonic welding was evaluated. Unidirectional tapes of E-glass-reinforcedamorphous poly (ethylene terephthalate) were laid up and consolidated in a filament winding machine that was modified with a set-up enabling ultrasonic welding. The obtained composite specimens were characterized by means of morphological and dynamic mechanical analysis as well as void content evaluation, in order to correlate welding parameters to composite properties.

“…The main modifications taking place in stone and wood exposed to outdoor elements arise from a combination of physical, biological and chemical phenomena, where water always plays a prominent role [19]. In order to preserve historical/artistic heritage from degrading phenomena, the use of protective coatings on affected areas and/or the consolidation and gluing of weakened parts [20,21,22,23] are often employed. The major essential properties required for protective/consolidating agents can be summarized as follows [24,25]: hydro-repellence, permeability to water vapor, reversibility or the possibility to re-treat the surface, durability, transparency and compatibility with the substrate and the capability to prevent the infiltration of contaminants or degrading agents from the atmosphere.…”

An innovative photopolymerizable microgel modified UV-cured acrylic-silica hybrid formulation was developed and characterized for possible use as protective coating for different substrates. A deep investigation, aiming at providing a strong scientific basis for the production of organic-inorganic (O-I) hybrids exhibiting phase co-continuity, was firstly carried out. The O-I hybrid first proposed in this study was obtained from organic precursors with a high siloxane content, which are mixed with tetraethoxysilane (TEOS) in such a way to produce co-continuous silica nanodomains dispersed within the crosslinked organic phase, as a result of the sol-gel process. The first part of the research deals with the selection and optimization of suitable systems through appropriate chemical modifications, in order to ensure that curing reactions can be carried out at room temperature and in the presence of UV radiation. Firstly, the silica domains are formed, followed by crosslinking reactions of the acrylic groups in the oligomer via a free radical polymerization. The crosslinking reaction was controlled with the use of a suitable photoinitiator. Most of the experimental work was devoted to understanding the morphology of the hybrid system, both in uncured and cured states, and to assess its final thermal and optical properties, using different experiential techniques.

“…Thanks to their physical and mechanical properties and especially their good reversibility, thermoplastic polymers are preferred over thermosetting resins [4,5]. In the last years, new materials and new methods have been investigated to consolidate wood [6][7][8]. Despite this, Paraloid B72 is still one of the most utilized consolidant products and the one that guarantee to conservators good consolidating performance [9].…”
