Design, Finite Modeling and Structural Performance of a One-Piece SMC Auto Hood

In response to identified industry needs for lightweight materials, Owens-Corning Fiberglas initiated a concentrated two-year program to advance the use of SMC technology. A project center was established utilizing Owens-Corning personnel from a variety of scientific disciplines including reinforcement development, resin development, mold design, design and structural analysis, production molding, machine technology and physical testing and mechanical testing. Its objective is to overcome concerns about cost and performance for applications requiring critical Class “A” finishes. Advances in SMC technology will be aimed at improving reproducibility, finish and production costs. The project will also develop data that will add to the characterization of SMC properties.

As a proof statement, the project center is developing, from initial design through limited production of parts, a one-piece automotive hood.
