Abstract
A composite material body () includes a first material layer () and a second material layer () overlapping the first material layer (). The first material layer () and the second material layer () are wound to form a flexible and circular rod. Impact absorption is effectively improved and impact resisting strength is enhanced because energy-absorber or damping material or its composition is attached into the composite material body (). Technical characteristics, effects and objects of this invention are achieved thereby.
