The Zimac hot bonder can control an aluminum layer, cut from sheet stock, and placed just under the bag and above the patch providing a quick method to obtain your cure. Cells are positioned on predefined centres; a uniform temperature profile is easily achieved of any size or shape desired. This is quickly done without resorting to buying a special blanket. Illustrated here is 12 inch diameter aluminum tile providing a resulting uniform temperature across a simulated 10 inch diameter patch on the the Carbon Graphite/Nomex fan cowl piece.
