Abstract
An industrial oven system for curing composite material parts can include an oven compartment configured to receive a composite material structure therein that extends along a majority of the length and/or width of the compartment, the compartment having an inner wall that defines a cavity between proximal and distal ends of the compartment. A shroud can be disposed circumferentially between the inner wall of the compartment and an outer wall of the composite material structure. The shroud defines a first longitudinal annular channel between the inner wall and an outer surface of the shroud, and defines a second longitudinal annular channel between the outer wall of the composite material structure and an inner surface of the shroud. The shroud is contoured to direct a heated airflow longitudinally along the annular channels and over the composite material structure to cure the composite material structure, the heated airflow generally being at a higher temperature than a surface of the composite material part. One or more contour elements of the shroud can direct more heat to a corresponding thicker portion of the composite material structure generally aligned with the contour ele…
