Co-molded cvj boot skirt for anti-slip performance

A method of constructing a boot for a constant velocity joint, comprising:

• molding a flexible hollow wall with a second material extending about a central axis between a first end and a second end, with the first end being molded forming at least part of a skirt portion configured for snug engagement with an outer surface of a housing of the constant velocity joint and the second end being molded forming at least part of a neck portion configured for snug engagement with an outer surface of a shaft extending away from the constant velocity joint;
• and
• bonding an annular inner portion, having an interior surface formed of a first material, to an inner surface of at least one of the skirt portion and the neck portion, the interior surface facing toward the central axis and being configured for snug engagement with the outer surface of at least one of the housing and the shaft,
• wherein the first material is provided having a first coefficient of friction and the second material is provided having a second coefficient of friction, the first coefficient of friction being greater than the second coefficient of friction.
