Abstract
A hollow metal tube and method making same are disclosed in which the tube includes a reinforcing sleeve compressively engaged with the interior of the tube. The sleeve is formed of carbon fibers in an epoxy matrix. The method of making the tube results in the wall of the tube being compressed against the sleeve, which imparts a high rate of wall recovery if the tube is impacted. Accordingly, the article is particularly useful as a ball bat or other tubular structure which may be subjected to external forces or impact.
