    • Methods of making the burnthrough resistant non-woven mat include forming the mat from glass fibers and at least two binders, a first binder having a vinyl component and a second binder having a strengthening component. The vinyl component may be, for example, ethylene vinyl chloride, and the strengthening component may be, for example, melamine formaldehyde. In one method, the vinyl component is added to the glass fibers by a beater addition process and the strengthening component is sprayed onto the glass fibers. 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.
    • 制造耐烧穿无纺布垫的方法包括从玻璃纤维和至少两种粘合剂形成垫,具有乙烯基成分的第一粘合剂和具有强化组分的第二粘合剂。 乙烯基组分可以是例如乙烯氯乙烯,并且强化组分可以是例如三聚氰胺甲醛。 在一种方法中,通过搅拌器加入方法将乙烯基组分加入到玻璃纤维中,并将强化组分喷涂到玻璃纤维上。 耐烧穿的无纺布垫可以与绝缘毯一起使用,并且可以特别适用于绝缘飞机。
