MBTs have also replaced the earlier monobloc [[steel]] armor with composite protection. Traditional [[RHA|rolled homogenous armor]] is combined with air gaps and materials made from [[synthetic fibres]] to form an armor sandwich often referred to as [[Chobham]]. The use of such [[composites]] arises from the huge advances in non-metallic materials science, particularly [[plastics]] and [[recycling]]. Chobham armor is significantly more effective than RHA of the same weight.
