Questa tesi riguarda le proprietà dielettriche e di assorbimento alle microonde della resina epossidica caricata di nanocariche. Tre differenti nanocariche a base di carbonio sono state usate in questa tesi: Carbon black (CB) nanofibre di carbonio (CNF) e nanotubi di carbonio (CNT). Inoltre,sono stati provati vari processi di dispersione delle nanocariche nella resina, per analizzare gli effetti della distribuzione delle nanocariche sulle proprietà dielettriche dei composti che ne risultavano. È stata misurata la permettività usando un sistema VNA nella banda-X (8,2-12,4 GHz) usando il metodo

Abstract:

This thesis describes the effects of climatic factors, particularly humidity and temperature on the properties of macromolecular substances, but also others, such as UV radiation, wind, water and oxygen. Furthermore, we introduce the definition and distribution of macromolecular substances. The next section describes the basic properties of dielectric materials. Much of the text is devoted to the description, production, curing, properties and utilization of epoxy resins. The last part deals with climate factors in general terms.

It was found that stress-induced changes of these fibres at molecular level are proportional to the macroscopic deformation applied. This correlation is unique for the fibres.

A really particular and innovative metal-polymer sandwich material is Hybrix. Hybrix is a product developed and manufactured by Lamera AB, Gothenburg, Sweden. This innovative hybrid material is composed by two relatively thin metal layers if compared to the core thickness. The most used metals are aluminum and stainless steel and are separated by a core of nylon fibres oriented perpendicularly to the metal plates. The core is then completed by adhesive layers applied at the PA66-metal interface that once cured maintain the nylon fibres in position. This special material is very light and forma

Abstract:

One of the greatest limitations to the use of polymer composites is the high cost of the techniques traditionally employed in their manufacture. Therefore, less Labour intensive, lower cost manufacturing methods such as resin transfer moulding (RTM) have been developed. Such processes require a resin with low viscosity at the processing temperature. Resins that exhibit good high temperature performance tend to be viscous, and are usually brittle when cured. Conventional toughening agents, such as polyethersulfone, further increase the viscosity of the blend. This work focuses on the use of hyp

Abstract:

Las resinas epoxi se encuentran entre los materiales termoestables más importantes utilizados en un gran abanico de aplicaciones tales como adhesivos, matrices para materiales compuestos, recubrimientos de superficies y encapsulamiento de componentes electrónicos. La principal razón de su amplio uso es la buena combinación entre resistencia a la tracción y a la corrosión, rigidez y buenas propiedades eléctricas. Sin embargo, debido a su elevado grado de entrecruzamiento, las resinas epoxi tienen una baja resistencia al impacto, la cual limita su uso en algunas aplicaciones específicas. Para co

Abstract:

The purpose of this study was to investigate the effects of mold temperature, initial resin temperature, and the vacuum, applied at resin exit ports, on the mechanical properties of epoxy matrix woven glasss fiber reinforced composite specimens produced by Resin Transfer Molding (RTM). For this purpose, six different mold temperatures (25&ordm<br>, 40&ordm<br>, 60&ordm<br>, 80&ordm<br>, 100&ordm<br>, and 120&ordm<br>C), two initial resin temperatures (15&ordm<br>and 28&ordm<br>C), and vacuum (0.03 bar) and without vacuum (~1 bar) conditions were used. Specimens were characterized by using ult
