Abstract
Abstract The invention relates to a composite material comprising an aluminum sheet and a reinforcement associated by a thermofusible composition. This material is characterized in that the thermofusible composition contains a group of fire-resistant agents and can be fixed on a layer of insulating fibers simply by calendering. It finds its application in reinforcement of thermal and acoustic insulating panels that must have a good fire resistance and a suitable mechanical resistance.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
103 words
A composite material comprising: (i) an aluminum sheet, and (ii) a reinforcement means formed of a fabric of glass mono- or multifiber yarn or an organic material; wherein the aluminum sheet is bound to the reinforcement means by a thermofusible composition comprising an ethylene copolymer, polypropylene or a polypropylene copolymer; wherein the thermofusible composition further comprises a fire-resistant agent which is at least one member selected from the group consisting of a bromo-aromatic derivative, a chloro-organic derivative, aluminum trihydrate, antimony trioxide and an antioxidizing agent; said fire-resistant agent being used in an amount of 70 to 90% by weight in the thermofusible composition.
Claim 2
Dependent Claim
103 words
A composite material comprising: (i) an aluminum sheet, and (ii) a reinforcement means formed of a fabric of glass mono- or multifiber yarn or an organic material; wherein the aluminum sheet is bound to the reinforcement means by a thermofusible composition comprising an ethylene copolymer, polypropylene or a polypropylene copolymer; wherein the thermofusible composition further comprises a fire-resistant agent which is at least one member selected from the group consisting of a bromo-aromatic derivative, a chloro-organic derivative, aluminum trihydrate, antimony trioxide and an antioxidizing agent; said fire-resistant agent being used in an amount of 70 to 90% by weight in the thermofusible composition.
Claim 3
Dependent Claim
12 words
