Abstract

Selon l'invention, les antériorités ont laissé une marge d'amélioration sur le plan de la réactivité du fait que les moyens de refroidissement s'appuyaient principalement sur un refroidissement naturel. L'invention concerne un matériau composite stratifié présentant une excellente réactivité. Ce matériau composite comprend une paire de substrats présentant des coefficients de dilatation thermique différents, et une couche isolante prise en sandwiche entre les deux substrats, cette couche isolante comportant au moins un entrefer. Comme un fluide, tel qu'un gaz ou un liquide, peut être acheminé vers l'entrefer, le réglage de température, refroidissement ou chauffage, peut être facilité par la température du fluide et la réactivité du matériau composite peut être améliorée, sans que la courbure ne soit sensiblement réduite.
