Abstract
In this thesis, a novel approach to producing three-dimensional hollow composite structures was studied. There are two variations of this process (Open Bladder and Closed Bladder) both using vacuum pressure. In the Closed Bladder approach, vacuum was used to inflate the bladder due to a reduction in the pressure on the outside of the bladder while inside a fully enclosed mold. In the Open Bladder approach, vacuum pressure was used similarly to traditional methods with the variation being that the part was made on the interior cavity of a mold. In the Open Bladder approach, a vacuum bag wrapped around the exterior of a mold, then entering the interior cavity through a passageway. Thereby forming an internal bladder. One of the objectives was to keep the process cost low for use in prototyping of composites. Vacuum infusion was the primary process used to maintain moderate mechanical properties and low cost. Experimental results revealed that both variations successfully formed parts. The Open Bladder approach was found to be more flexible and showed some potential to have commercial applications.
