Abstract
A sporting implement, such as a blade for a hockey stick, may include an outer layer, a core, and a recovery gel positioned between the core and the outer layer. The recovery gel can form a film, and the recovery gel can be compressible, shape recoverable, and pressurized to a predetermined pressure. The recovery gel can be configured to provide an integrated agent for filling cracks that appear during use of the blade. The recovery gel can be configured to absorb energy impacts between the outer layer and the core. When a crack appears, the predetermined pressure can be relieved inside the crack and fills a cavity formed by the crack to provide cohesion between the outer layer and the core to recreate a new material in the place of the crack. The recovery gel can be configured to help prevent cracks from propagating and actively heals potential damages by reducing stiffness loss caused by cracks.
