Patent

CA 2467135

A composite laminate structure formed from at least one high-strength, high- stiffness fiber-resin composite structural lamina laminated to at least one fiber-resin composite damping lamina, wherein the resin matrix of the structural lamina resides below its glassification temperature (T g) and wherein the resin matrix of the damping lamina resides above its glassification temperature during normal use temperatures, thereby providing a high-strength laminate with improved damping properties.

Une structure laminée composite formée d'au moins une lame structurelle laminée en matériau composite fibre/résine haute résistance et haute rigidité et jusqu'à au moins une lame d'amortissement du son en matériau composite fibre/résine, dans laquelle la matrice de résine de la lame structurelle reste en dessous de sa température de vitrification (T g) et dans laquelle la matrice de résine de la lame d'amortissement du son reste au-dessus de la température de vitrification dans des conditions de températures d'utilisation normales, fournissant ainsi une lame haute résistance ayant des propriétés d'amortissement améliorées.
