From another site that I go to:
"A memo in part from the NCAA Baseball Rules Committee:
SUBJECT: Composite Bat Moratorium.
This correspondence is being sent on behalf of the Baseball Rules Committee, alerting the college baseball bat manufacturing community to an important action being taken in regard to certain bats that have been used in NCAA competition. After significant dialog and review of research collected during the Division I Baseball Championship, the committee is proposing an immediate and indefinite moratorium on the use of composite barreled bats. The committee believes this action is needed in order to protect the integrity of the game and to enhance the safety of the student-athletes. "
The owner of a bat company posted it and is a very reliable source.
