Abstract: The invention relates to an encapsulation composition for the storage or the confinement of waste which is toxic to health and/or the environment, comprising a resin composition containing at least one epoxy resin, and a hardening composition containing at least one polyamidoamine and at least one aromatic polyamine, said encapsulation composition having an aromaticity rate which is equal to, or higher than, 35%. The invention also relates to the use of said composition for encapsulating said waste.

Abstract: The invention provides a powder pre-preg comprising as sole resin a vinyl ester resin having a Tg in the range of ?5 to +30° C. and a melt viscosity @100° C. in the range of 2 to 75 dPa·s, which can be used in making a composite at a temperature as low as 80° C.

Abstract: Disclosed herein are an article and a method for preparing the article. The article comprises at least one layer A comprising fibers embedded in a composition comprising at least one vinyl ester resin; and a layer B comprising from 40 to 100% by weight relative to the total weight of said layer B of at least one thermoplastic polyester; from 0 to 60% by weight relative to the total weight of said layer B of a polyolefin composition; said composition comprising at least one polyolefin; and from 0 to 20% by weight relative to the total weight of said layer B of at least one additive selected from compatibilizing agent and/or impact modifier. Layer B may comprise a blow-molded layer, an injected-molded layer, an extruded-thermoformed layer, a sheet-extruded layer, a pipe-extruded layer, and an injection stretch blow-molded layer. Layer A may be in contact with layer B.

Abstract: The invention relates to a solar reflector for concentrated solar power plants, comprising a substrate a) in composite material based on resin reinforced with cut fibers, said substrate having means b) for attachment without either perforation or gluing, and a metallic reflective coating layer c). The reflector of the invention is used in solar collectors and in solar plants operating on concentrated solar power, more particularly for producing electricity, steam and/or heat.
