We are currently conducting a research project on the use of pre-preg carbon fiber filament for the production of variable architectural building units. This required the design and construction of a baking oven. As the pre-preg only needs to be baked at a low 265 degrees Fahrenheit we could use infrared lamps as our heat source. The exterior dimension of the oven is 4′x4′x8′ and is constructed from a steel tube frame. Roxul is used as insulation with diamond mesh serving as the interior walls of the oven and concrete tile board the floor. The exterior is clad in OSB. Six Nutone heat lamp fixtures were used to hold the twelve 250w infrared lamps. We later discovered we needed to add eight more lamps to acquire the proper temperature. These were affixed to the oven ceiling with simple off the shelf ceramic fixtures. It was decided to run the two sides of the oven on separate circuits as it allowed us to run it from a 120v power source – this also proved useful as during one bake we lost a relay for one side of the oven and were able to maintain temperature by just using the working side. The temperature is regulated by a PID controller from Auber Instruments. Construction images and parts baking image below:
