This work addresses the development of composite materials that contain metallic load-bearing cords with the aim of combining outstanding mechanical performance with added functionality, including electrical conductivity, data transmission, and temperature ...
We study mechanical reinforcement in a widely used epoxy matrix with the addition of graphene nanoplatelets (GnPs) and various mixture ratios of carbon nanotubes (CNTs) with GnPs. Two different dimensions of GnPs were used with flake sizes of 5 mu m and 25 ...
Ferroelectric ceramic – polymer composites have a unique mix of electrical and mechanical properties. Piezoelectric and pyroelectric activity, a wide range of dielectric constants and high breakdown strength are combined with mechanical flexibility, formab ...
Nowadays, composite materials are increasingly used in high technology fields such as aerospace and automotive because of the combination of excellent mechanical performance and lightweight. For these characteristics, classical metal alloys are progressive ...
We report results on the development of an innovative fast-curing coupling method using a UV-curable epoxy primer based on a cycloaliphatic di-epoxide resin to bond metallic wires and a thermoplastic polyurethane matrix. The curing kinetics of the primer a ...
In continuous composite production, for example the continuous impregnation of steel wires or cords with a thermoplastic polyurethane matrix, an ideal and cost-effective solution to improve interfacial adhesion and durability would be to deposit and cure a ...
In this thesis, we proposed to study polymer-based thick-film resistors (TFRs) made of graphite particles dispersed in an epoxy matrix. Three main axes were investigated: formulation of the composites, characterization with the determination of electrical, ...
Healing of epoxy resins can be accomplished using a combination of embedded ethyl phenylacetate (EPA) solvent loaded capsules and shape memory alloy (SMA) wires. Upon crack formation, the EPA solvent diffuses in the resin and induces swelling which tends t ...
Over the past decades the use of composite materials has enormously increased, especially in the aeronautical, automotive, and energy production industries. These materials allow to build lighter and larger structures which are more efficient. However, by ...
We report results on the development of an innovative fast-curing coupling method using a UV-curable epoxy primer based on a cycloaliphatic di-epoxide resin. The materials to bond are metallic wires and a thermoplastic polyurethane matrix. The curing kinet ...
