Abstract
A flexible multilayer battery pack insulator for an electric vehicle has a multilayer wall including a plurality of layers of interlaced mineral material including an inner layer having a first exposed, outwardly facing surface and an outer layer having a second exposed, outwardly facing surface. A first flame-resistant coating is bonded to at least one of the plurality of layers. A pressure-sensitive adhesive is bonded to the first exposed, outwardly facing surface of the inner layer. At least one filament fixes the plurality of layers to one another.
Claims20
A flexible multilayer battery pack insulator for an electric vehicle, comprising:
- a multilayer wall including:
- a plurality of layers of interlaced mineral material, said plurality of layers including an inner layer having a first exposed, outwardly facing surface and an outer layer having a second exposed, outwardly facing surface;
- a first flame-resistant coating bonded to at least one of said plurality of layers;
- a pressure-sensitive adhesive bonded to said first exposed, outwardly facing surface of said inner layer;
- and
- at least one filament fixing said plurality of layers to one another.
A method of constructing a flexible multilayer battery pack insulator, comprising:
- interlacing mineral material to form an outer layer having an outer surface and an inner surface;
- bonding a first flame-resistant coating to the outer surface of the outer layer;
- interlacing mineral material to form an inner layer;
- arranging the outer layer and the inner layer in overlying relation with one another;
- stitching at least one filament and fixing the outer layer and the inner layer to one another to form a multilayer wall;
- bonding a pressure-sensitive adhesive to the inner layer;
- and
- cutting the multilayer wall to size.
