METHOD AND BLADDER APPARATUS FOR FORMING COMPOSITE PARTS

A material forming apparatus and method for shaping a material to a forming tool having complex contours. The material forming apparatus may comprise a bladder sealed to a support structure, cooperatively forming a hollow space therebetween into which air or another gas may be pumped to inflate the bladder. The forming tool may comprise a protrusion of any shape to which the material may conform. The material may be placed between the bladder and the protrusion and the support structure may be actuated toward the forming tool. As the support structure progresses toward the forming tool, an area of material pressed against the protrusion by the bladder increases in an outward direction. A pressure regulator may regulate an amount of pressure applied to the material by the bladder as the bladder presses the material against the forming tool.
