Mazda launches first LFRT front-end module in North America. (Your Business: In Brief).

Long-fiber reinforced thermoplastics (LFRT) have scored a first on this continent with the unveiling of the new front-end module for the all-new 2003 Mazda 6 mid-size cars from Mazda Motor Corp. of Japan. The new vehicles are scheduled for first production this month and will go on sale in January. The cars contain a structural front-end module and structural front and rear door modules made of 40% long glass in polypropylene. A special low-viscosity, high-crystallinity PP formulation of Verton MFX from LNP Engineering Plastics, Exton, Pa., is said to provide more than 30% higher flow than standard long-glass PP. This reportedly enables molding thinner walls and results in a resin-rich surface. Also, easier flow facilitates parts integration: The front-end module holds the radiator components, fan assembly, and hood latch. The door module holds the speakers, latch assembly, door-lock actuator, and window regulator.

The front-end module weighs 7.74 lb and is injection molded by DDM Plastics, Inc., Tillsonberg, Ont. The door modules weigh about 2.34 lb and are injection-compression molded by Automold of America, Inc. in Auburn Hills, Mich. Injection-compression permits molding thinner walls--less than 3 mm--while reducing shear on the glass so as to preserve longer fibers for higher impact strength.
