Smaller parts, a wider range of resins and reinforcements,and retrofittable molding equipment were among the news indirect-compounded long-fiber thermoplastics presented at a recent Plastics Technology conference. Extrusion and thermoforming are also new extensions of this process.
The focus this year at the international JEC Composites Show in Paris was not so much on brand-new processes as on adapting existing processes and materials for mass production, especially of large parts with critical structural demands. Attracting the most attention was wind energy, where composite material usage is growing more than 17%/yr, according to Gurit (formerly SP Systems), a Swiss-based global prepreg supplier with U.S. operations.
At the K 2007 show in Germany, Dieffenbacher GmbH (parent of Dieffenbacher North America Inc., Windsor, Ont.) introduced a "direct" mixing-and molding process for SMC, analogous to its D-LFT technology for long-fiber thermoplastics.
Topping the news from the year’s biggest composites show are PP ballistic panels, “stealth” composites, thermoplastic RTM, new tooling concepts, microwave curing, “instant” SMC, and laser projection for QC and ply layup.
New compression presses from Dieffenbacher North America Inc., Windsor, Ont., are said to reduce energy consumption by at least 50% while also trimming cycle times.
Direct long-fiber thermoplastic (D-LFT) compounding and molding is getting ready to expand beyond non-appearance structural automotive parts to exterior body panels.
Paintless in-mold film decorating and carbon-fiber composites are making inroads in appearance and structural parts. Blow molding is finding new interior applications. And long-fiber thermoplastics are cutting weight and cost on the inside and outside of new passenger vehicles.
Although more widely used in Europe, in-mold laminating is gaining a foothold in U.S. automotive interiors. Molders can choose from a handful of different process technologies that promise labor and other cost savings.
Europe's third largest automotive molder, Faurecia, uses five different long-glass thermoplastic molding processes, more than any other molder in the world. It invented half of them, including the world's first in-line compounding- and-injection process.
