Preferably, described elastomeric layer is cylindric, is equivalent to fully to have filled the inside of the carbon fibre initial rinse layer of cloth of ring-shaped section and ring-shaped, can give thus maximum elastic characteristic and more stable shock-absorbing function is provided.

In addition, described elastomeric layer also can be clipped in the middle of the described carbon fibre initial rinse layer of cloth.Because elastomeric layer is clipped in the middle of the carbon fibre initial rinse layer of cloth, the rigidity effect of carbon fibre initial rinse layer of cloth that has been equivalent to " interference ", therefore, attached compared to two kinds of above-mentioned elastomeric layers only needs a small amount of elastomeric layer can realize good elastic effect.

Preferably, the cross section of described elastomeric layer is annular, rigidity effect that thus can relatively complete ground " interference " carbon fibre initial rinse layer of cloth.

Particularly, the material of described elastomeric layer for example is selected from: polyethylene, aramid fiber, nylon or have identity function and any elastomeric material easy to implement.

Especially, the described polyethylene nonwoven that is made of polyethylene, aramid fiber, nylon is made of superhigh molecular weight polyethylene fibers, therefore can satisfy flexible requirement again when obviously not increasing racket weight.

The utility model has proposed a kind of racket on the other hand, and it comprises frame, handle and above-mentioned middle tube of battledore.

With respect to prior art, the utility model can be so that the elasticity of the middle pipe of racket and toughness promote, and then the risk of pipe fracture in reducing, and resilience time of racket when having reduced middle pipe distortion.
