The α-relaxation for the ELP system deviates significantly from that for HBPEI, but superposes on that for the epoxy resin. The fully cured thermoset displays both β- and α-relaxations. In DMA measurements, both α- and β-relaxations are observed in all systems and in both the uncured...
From the data in Table 2, it is possible to observe the effect on Tg of the hardener used to cure the epoxy and a further effect brought about by the hybridization in the presence of DES performed on each resin/hardener couple. The significant reduction of the Tg measured only on the ...

The curing agent trimethylhexamethylenediamine (TMD) was then added to the mixture with a mass ratio to epoxy resin of 6:10. The mixture was placed in a vacuum at 76 cm Hg pressure for 30 min to remove any trapped air, and was then poured into a silicon mould. Finally, the epoxy ...
A possible advantage of the use of nonwoven for FRP lies in the better availability of the fibres to be embedded in the resin system. Nonwoven is an obvious choice because of the fibre characteristics of the flax and rCF. However, fibres can be damaged because of the mechanical stress ...
Keywords: cycloaliphatic epoxy resin; composites; thermal conductivity; boron nitride; thiol-epoxy 1. Introduction Nowadays, electronic and electrical industries have an increasing need to dissipate the heat of devices, which is produced by the Joule effect. This leads to a continuous demand of ...
