The present invention discloses a composite material comprising one or more fillers and a polymerizable resin base, wherein said one or more fillers comprise at least one filler ingredient, said filler ingredient(s) being present in a metastable first phase and being able to undergo a martensitic transformation to a stable second phase, the volume ratio between said stable second phase and said metastable first phase of said filler ingredient(s) being at least 1.005, and wherein said material further comprises one or more water- or acid- releasing agents; as well as a corresponding method of controlling the volumetric shrinkage of a composite material upon curing.

[EN] The present invention discloses a composite material comprising one or more fillers and a polymerizable resin base, wherein said one or more fillers comprise at least one filler ingredient, said filler ingredient(s) being present in a metastable first phase and being able to undergo a martensitic transformation to a stable second phase, the volume ratio between said stable second phase and said metastable first phase of said filler ingredient(s) being at least 1.005, and wherein said material further comprises one or more water- or acid- releasing agents; as well as a corresponding method of controlling the volumetric shrinkage of a composite material upon curing. [FR] L'invention porte sur un matériau composite comportant une ou plusieurs charges et une base de résine polymérisable. La ou les charges comportent au moins un ingrédient présent dans une première phase métastable et susceptible de subir une transformation martensitique en une deuxième phase stable, le rapport volumique entre ladite deuxième phase stable et ladite première phase métastable étant d'au moins 1,005, ledit matériau comportant en outre un ou des agents de libération d'eau ou d'acide. L'invention porte par ailleurs sur un procédé associé de régulation de la contraction volumique d'un matériau composite lors de sa prise.
