Developments in preform technology are increasing the viability of SRIM in the production of high volume, low cost components, particularly for the automotive sector. These developments focus on automation and the use of low cost, chopped fibers. A directed fiber process, rather than continuous strand mat thermoforming, is optimal for the production of components with complex geometries, deep draws, and tight radii. A major disadvantage, however, is that only random orientation is possible. Both Dow and Ticom have developed automated processes for preform technology. Bkudd's slurry process uses chopped glass rovings in water to make preforms. Owens/Corning's robotic Programmable Powdered Preform Process features 40 second fabrication cycles.
