  • Patent number: 11874188
    Abstract: The present invention relates to the sector of self-diagnostic composite materials. In particular, the invention presents an agent, which can be cross-linked together with a curing agent in a matrix, e.g. an epoxy resin, and fibres, e.g., carbon fibre, in order to obtain a composite material containing a reporting probe capable of detecting stress, fatigue and microscopic cracks in the material with high spatial resolution and sensitivity.

  • Publication number: 20210395440
    Abstract: The present invention relates to a tape comprising an epoxy based resin having ester groups and ethylenically unsaturated groups, alternatively a hybrid resin. The tape of the invention can be used for insulation in electrical machines, especially in high voltage machines. Preferably, the tape of the invention is used in combination with a composition for impregnating and/or coating a substrate comprising the tape of the invention, wherein the composition further comprises a second epoxy based resin having ester groups and ethylenically unsaturated groups, also an hybrid resin, a diluent and an initiator for a radical polymerization.

  • Patent number: 4755373
    Abstract: Titanates of barium, strontium, or mixed barium and strontium consisting essentially of solid, non-aggregated particles having diameters ranging from 0.05 to 1 micron and a narrow particle size distribution expressed by the polydispersity index, dw/dn, not greater than 1.20, where dw is the weight average diameter and dn is the number average diameter, said particles being essentially perfectly spherical with a total mean axial ratio of at least 0.93. These titanates are prepared by a process which comprises precipitating of a peroxidic precursor having the same morphological characteristics of the titanates. The peroxidic precursor is obtained by heating an alkaline solution comprising a complex of a titanium compound with a peroxidic compound, an M.sup.2+ compound, wherein M is Ba, Sr or mixtures thereof, and a compound Z capable of complexing with the M.sup.
