Abstract
Disclosed is an elastomeric bladder tool and related systems and methods. In one embodiment, the elastomeric bladder tool comprises an elastomeric inner layer substantially defining an inner cavity of the elastomeric bladder tool, an elastomeric outer layer substantially defining an outer surface of the elastomeric bladder tool, and a permeable middle layer positioned between the elastomeric inner layer and the elastomeric outer layer. The permeable middle layer has greater permeability than both the elastomeric outer layer and the elastomeric inner layer to allow for evacuating of gases that have entered the permeable middle layer.
