Abstract
A burnthrough resistant non-woven mat is made of a glass fibers and includes a binder having a vinyl component and a strengthening component. The vinyl component may be, for example, ethylene vinyl chloride, and the strengthening component may be, for example, melamine formaldehyde. The burnthrough resistant non-woven mat may be used in conjunction with an insulation blanket, and may be especially suited to use in insulating aircraft. Methods of making the burnthrough resistant non-woven mat are discussed.
Claims52
A fire barrier mat, comprising:
- a nonwoven mat comprising glass fibers;
- and
- a binder including a vinyl component.
An insulation product, comprising:
- an insulation blanket;
- and
- a fire barrier mat adjacent one side of the insulation blanket, the fire barrier mat including a nonwoven mat comprising glass fibers and a binder that includes a vinyl component.
A method of making a fire barrier mat, the method comprising:
- providing fine glass fibers having an average diameter less than 4 microns;
- providing coarse glass fibers having an average diameter greater than 6 microns;
- forming a mat comprising the fine and coarse glass fibers using a wet lay process;
- and
- drying the mat.
A burnthrough resistant non-woven mat:
- having an area weight of less than about 150 g/m2;
- and
- comprising inorganic fibers having an average fiber diameter of less than about four microns and inorganic fibers having an average diameter greater than about six microns, the inorganic fibers having an average fiber diameter of less than about four microns and the inorganic fibers having an average diameter greater than about six microns being formed into a nonwoven mat, with the inorganic fibers having an average diameter of less than about four microns comprising fibers having greater than about 93 weight % SiO2, and the inorganic fibers having an average diameter greater than about six microns being made from basalt.
A burnthrough resistant non-woven mat:
- having an area weight of less than about 150 g/m2;
- and
- comprising inorganic fibers having an average fiber diameter of less than about four microns and inorganic fibers having an average diameter greater than about six microns, with the inorganic fibers having an average diameter of less than about four microns comprising inorganic fiber comprising greater than about 5 weight % iron oxide.
A burnthrough resistant non-woven mat:
- having an area weight of less than about 150 g/m2;
- and
- comprising inorganic fibers having an average fiber diameter of less than about four microns and inorganic fibers having an average diameter greater than about six microns, with the inorganic fibers having an average diameter of less than about four microns comprising greater than about 93 weight % SiO2, wherein the inorganic fibers having an average diameter greater than about six comprise inorganic fibers made from crystallizable glass comprising greater than about 5 weight % iron oxide and wherein the inorganic fibers having an average diameter greater than about six comprise inorganic fibers made from basalt.
