Abstract:
A method for coupling a first porous insulation member to a second porous insulation member, each of the first and second porous insulation members being formed of a fibrous, low-density silica-based material, the method comprising the steps of:providing a ceramic/organic thermal setting binder having a thermal set organic binder and a ceramic binder selected from a group of binders consisting of glass and ceramic; applying the ceramic/organic thermal setting binder between a pair of mating surfaces formed into the first and second porous insulation members; heating the first and second porous insulation members to a first predetermined temperature to cause the thermal set ceramic/organic binder to distribute the binder through a joint formed by the mating surfaces of the first and second porous insulation members and thereafter cure the organic binder to form a bonded joint; heating the bonded first and second porous insulation members to a second predetermined temperature to burn out the thermal set organic binder; and firing the bonded first and second porous insulation members at a third predetermined temperature to cause the ceramic binder to fixedly couple the mating surfaces of the first and second porous insulation members to one another.
