ABSTRACT:
The present invention comprises a method for protecting carbon composite materials from edge or surface damage during handling and manufacturing. The method comprises forming a protective silicon coating on selected surfaces of the carbon composite material to by forming a silicon bearing suspensoid coating on the surface of the carbon composite to be protected, and drying the suspensoid to a solid. In one embodiment, the suspensoid is formed by dissolving sodium silicate in water which is then mixed with an acid salt to form an irreversible gel. The suspensoid is either formed and then deposited on a surface area or formed in place through interactions between surface coatings of the separate compounds. The irreversible gel can be heated to remove the water and form a solid protective coating from the suspensoid.
