Johns Manville
develops Direct Roving LFTplus for Thermoplastic Composite
Applications:
Bad Homburg (July 5, 2002) ---- Long Fiber Technology (LFT) is a fast-growing,
cost-efficient technology primarily focused on structural and semi-structural
automotive applications. LFT uses longer fibers than the normal chopped
strands in injection molding granulates to achieve better mechanical
performance in structural components such as front-ends, bumper beams,
instrument panels or spare wheel pans.
The new DR LFTplus allows Johns Manville and its customers
to develop new cost effective applications in the European and North
American automotive markets. The sizings of DR LFTplus are
developed for PP, PA and PET resins.
DR LFTplus, initially displayed at the JEC in 2002 in Paris
has two key manufacturing concepts: (1) Direct-LFT, where the glass
roving and the polymer resin are compounded on-line into a compression
or injection molding operation, or (2) the traditional two-step
process, with the initial fabrication of long fiber reinforced granulates
via extrusion and the final injection of compression molding process
using the LFT granulates.
Johns Manville, a Berkshire Hathaway company, is a leading manufacturer
