硬式野球バットと球の高速衝撃(第2報, CFRP円筒と硬式球の衝突)
1992
In the previous report, impact phenomena of baseball bats made of aluminum alloy and balls were examined. In order to clarify questions pertaining to the application of some new industrial materials to athletic equipment, the dynamic deformation and failure of cylindrical pipes made of carbon-fiber-reinforced plastics (CFRP) which are impacted by balls are studied experimentally in this paper. It is pointed out that the delamination of CFRP pipes precedes the destruction of carbon fibers and the strength of CFRP pipes is reduced abruptly even if the impact velocity is relatively low.
