Abstract
An apparatus comprising a fiber placement head assembly and an infrared heating assembly is provided. The fiber placement head assembly includes a compaction roller assembly and a feeder assembly. An infrared heating assembly, a cooling mechanism, temperature sensors, and a controller are operably coupled to the fiber placement head assembly. The infrared heating assembly includes an infrared heater that generates a heating profile. The heating profile defines a heating zone on either a tool or previously laid tows. If the burn point of either the tool or previously laid tows within the heating zone is approached, the controller, which receives temperature readings from the temperature sensors, simultaneously disables the infrared heater and activates the cooling mechanism. As such, the tool and the previously laid tows are protected from being ruined due to an over temperature condition.
