Use of an aqueous deicing/anti-icing composition for reducing carbon fibre degradation

Abstract

Disclosed is the use of an aqueous deicing/anti-icing composition for reducing carbon fibre degradation. Said composition comprises 40-60% by weight of at least one alkali metal carboxylate and 0.1-2.0% by weight of microfibrillated cellulose. The microfibrillated cellulose comprises at least one hydroxyalkyl cellulose. The balance to 100% by weight is achieved by water and said composition has a pH of 9-12. Disclosed is also a method for reducing carbon fibre degradation of an aqueous deicing/anti-icing composition in brakes. The method comprises applying the composition on an area selected from airfield runway, airfield taxiway, street, road, cycle way, footpath, sidewalk, bridge, backyard, parking area and sportsground. Disclosed is also the use of microfibrillated cellulose as a deicing/anti-icing composition additive for reducing carbon fibre degradation in airplane brakes.
