Up to now, the number-one biopolymer in commercial use, polylactic acid or PLA, has been available mainly from one supplier and in a limited range of varieties. But there appear to be a number of new sources waiting in the wings, who are preparing a profusion of new PLA variants—copolymers, alloys, “engineering” PLA and even “do-it-yourself” PLA.

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.
