A methodological approach for monitoring the curing process of fairing compounds based on epoxy resins

Rheological, Mechanical and Morphological Characterization of Fillers in the Nautical Field: The Role of Dispersing Agents on Composite Materials

“…Indeed, by covering these external surfaces, coatings are most exposed to aggressive environments, such as seawater, marine atmosphere and thermal variations, thus providing a significant protection effect. Additionally, coatings must provide aesthetic properties typical of luxury products (e.g., brightness, light reflection, durability over time) [ 5 , 6 , 7 , 8 ]. Such performances are achieved through complex multilayer structures, namely painting systems.…”

“…Thus, it is not surprising that both the physicochemical features and the application of this layer are crucial for smoothing the surface, filling possible defects or voids and contributing to isolate the hulls [ 9 ]. However, few studies are available in the literature for these specific materials [ 5 , 6 , 10 , 11 ]. Fillers are usually made of two different parts consisting in an A component (e.g., epoxy resin) and a B component (e.g., curing agent based on a polyamide group), which, once mixed together in opportune ratios, form the final composite materials to be applied.…”

“…In addition to the polymeric matrix, different types of additives, extenders and pigments are present in the formulation and require to be well dispersed in the matrix in order to exploit their functions [ 12 , 13 ]. The most common additives are rheological modifiers, antifoams and dispersing agents [ 5 , 12 , 14 , 15 , 16 , 17 ]. Rheological additives act on the viscosity of the samples, allowing to increase or reduce their tendency to flow and avoid the sagging phenomenon during the application step (i.e., thixotropic recovery), whereas anti-foams are used to obviate the formation of foams during the dispersion of extenders in the matrix phase [ 18 , 19 , 20 ].…”

The effect of the heat treatment on the crosslinking of epoxy resin for aviation applications

“…One of usually applied technique to study the crosslinking of the resin is to determine its hardness. The Dynamic Mechanical Analysis (DMA) and Differential Scanning Calorimetry (DSC) allow to define the thermal properties of the resin, in particular the region of the glass transition T g [48][49][50][51][52]. The typical Fourier Transformed Infra-Red spectra for epoxy resin are known, so any additional peaks obtained during FT-IR-measurements will inform about the unusual behavior of the material [53,54].…”

A phosphorus/silicon/triazine‐containing flame retardant towards flame retardancy and mechanical properties of epoxy resin

“…As a typical thermoset resin, epoxy resin is widely used in exterior coatings of ships, base materials of electronic parts and structural materials of wind turbines due to its good corrosion resistance, low shrinkage rate and desirable mechanical properties. [1][2][3][4] In addition, epoxy resin, with excellent dielectric property, chemical resistance, and relatively low price, is expected to replace phenolic resins and be widely used in circuit boards. 5,6 With the rapid development of the communication field, especially the widespread popularity of 5G communication, the heat generated by electronic equipment during operation has increased greatly compared with the past, so the flame-retardant performance of the matrix material has become the primary consideration of designers.…”
