Abstract: Polymers offer a lightweight, low cost option for solar hot water system components. Key to the success of polymer heat exchanger components will be the long term mechanical performance of the ...

Abstract: A nonlinear model-based control method is proposed and validated for controlling, estimating and optimizing the cure in composite parts. During the cure, the exothermic reaction causes temperature ...

Abstract: In thermoplastic tape-laying with in-situ consolidation, a laminated composite is constructed by the local application of heat and pressure. A moving head, applying heat and pressure, lays down ...

Abstract: In thermosetting composite manufacturing, part thickness, mold temperature, pressure, and resin kinetics can affect the uniformity of cure in the finished part. If the interaction of these ...

Abstract: The mechanical behavior of perforated, chopped fiber reinforced polymer plates is measured in three point bend tests to determine if an equivalent elastic modulus can be applied to fiber filled ...

Abstract: The structural and thermal feasibility of a self-supporting sandwich panel for energy efficient residential roof applications is assessed. The assessment is limited to symmetric sandwich panels ...

Abstract: This paper presents an analytical model and an experimental study of adhesion and fluid shear removal of calcium carbonate scale on polypropylene and copper tubes in laminar and turbulent water ...

Abstract: Heat transfer rates of a single horizontal tube immersed in a water-filled enclosure tilted at 30 deg are measured. The results serve as a baseline case for a solar water heating system with ...

Abstract: The design of insulated metal roof panels that meet both the structural and hygrothermal performance requirements for a conditioned attic/roof system is presented. The two panel designs, referred to as the truss core and ...

Abstract: Two roof panel designs for residential applications were developed to span from ridge to soffit without intermediate supports. The two designs, the truss core and the stiffened plate, incorporate both structural and ...
