No, composite bats, including those that use carbon fiber, have been banned for use in Little League.
no but 9&10 year old's can
At the moment (1/11/11), Little League Baseball has disallowed the use of composite bats in Little League Baseball. The Combat B1, B2 and B3 are all composite bats which, if the current rule stands, will not be allowed for Little League play. There are rumors that Little League Baseball is considering an exception but as of now the list of officially recognized bats is on this link: http://www.littleleague.org/learn/equipment/approvedcompbats.htm
No you are not. The bats used must be Little League approved. Most leagues will provide bats if you do not want to spend the money to pay for one for your child yet.

Yes, but why use it, it isn't better than aluminum
Only some composite bats are approved. i.e. the combat b4 and the demarini cf4. Go tothe related link for more bats.
aluminum bats are only used from college baseball, to little league, they only use wood bats in the majors and all minor leagues
Little League ball players use Wilson baseballs.
Most Senior League bats have a 2-3/4 inch barrel. In a league that uses Senior League bats, you should still be able to use a bat with a smaller barrel if needed.
