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.
