Abstract
(EN)
A composite material includes an elastomer matrix, a set of first capsules containing a polymerizer, and a set of second capsules containing a corresponding activator for the polymerizer. The polymerizer may be a polymerizer for an elastomer. The composite material may be prepared by combining a first set of capsules containing a polymerizer, a second set of capsules containing a corresponding activator for the polymerizer, and a matrix precursor, and then solidifying the matrix precursor to form an elastomeric matrix.

L'invention concerne un matériau composite incluant une matrice élastomère, un premier ensemble de capsules contenant un agent de polymérisation, et un second ensemble de capsules contenant un activateur correspondant pour l'agent de polymérisation. L'agent de polymérisation peut être un agent de polymérisation d'élastomère. Le matériau composite peut être élaboré par combinaison d'un premier ensemble de capsules contenant un agent de polymérisation, d'un second ensemble de capsules contenant un activateur correspondant pour l'agent de polymérisation et d'un précurseur de matrice, puis solidification du précurseur de matrice pour former une matrice élastomère.
