Unlike flapping birds and insects, bats possess membrane wings that are more similar to many gliding mammals. The vast majority of the wing is composed of a thin compliant skin membrane stretched between the limbs, hand, and body.he musculoskeletal system of bat wings affords the potential to adjust membrane deformations in several ways. The boundary of the membrane is set by the articulated wing skeleton, which dictates membrane position and orientation.
Two-piece bats generally have less vibration in the handle due to the separation of the handle and barre. Alloy vs. Composite vs. Hybrid. Alloy bats are generally constructed with a one-piece design out of aluminum or aluminum that is mixed with other metals to make a stronger product. The advantage to this strength is that it allows alloy bats can have thinner, more responsive barrel walls. Composite bats, on the other hand, are made out of a mixture of carbon fiber, graphite, fiberglass, and sometimes Kevlar. Hybrid bats feature a two-piece design in which an alloy barrel is bonded to a composite handle.
