What is a Composite Bat

Composite bats are made of a carbon fiber, graphite and other composite materials.  They are held together by laminate glues.  These bats have been used and accepted in softball and baseball for the last 15 or so years.

Breaking in Period

Those that have played softball or baseball know that a composite bat in not  ” hot out of the wrapper “.    It takes upwards to a full season to get it broken in to its maximum performance.

The Science of Bat Rolling was studied by professors of Washington State University.  The documented results clearly show that the bats get much hotter after they are rolled.

Advantages of a rolled bat

  • Adds 20 – 50 feet of distance to a well hit ball
  • Can increase the life of the bat
  • Allows a player to hit a bat to its maximum hitting potential, instantly out of the wrapper
How The Bats Are Made 

Composite bats are made up of fiber cloth and glues.  Layers of cloth are stacked with the glues and then heated to high temperatures.  Once the bats are cooled, they become very solid and rigid.

Rolling Process

When the  bats are placed between the special rollers of our machines.  The rollers turn under compression and loosen up the fibers from the glues.  Once loose, the fibers act as a spring board. The bat  now has a trampoline effect which launches the balls further.

The results can be dramatic.  It can be the difference between outs in the outfield or circling the bases
