COLUMNS 4 From the Editor 6 Past, Present & Future 8 Perspectives & Provocations 10 Design & Testing 12 G ardner Business Index: Composites Fabricating 24 Work In Progress Contributing writer Peggy Malnati reports on a multi-year research program that involves the American Chemistry Council's Plastics Division and Michigan State University, which has yielded surprisingly effective results in its quest to develop reversible adhesively bonded joints, an outcome with far-reaching practical implications. » DEPARTMENTS 14 Trends 41 Calendar 42 Marketplace 42 Ad Index 43 Showcase » ON THE COVER The twin-engine, seven-seat DA62 on CW's cover this month is the most recent entry in the general aviation market from Diamond Aircraft (Wiener Neustadt, Austria), which has from its inception applied advanced composites to the primary structures of its aircraft. The company's aircraft designs flow from a push-the-limits design culture. Get an inside look at this airframer's opera- tion on p. 28.

FE ATURES 28 CW Plant Tour: Diamond Aircraft Austria, Wiener Neustadt, Austria Given all the attention paid to composites use in today's newer commercial aircraft, it is sometimes easy to forget that those who build general aviation (GA) aircraft not only embraced composites long before the major airframers, but also continue to do so in ways unheard of in the big planes. Composites use in the GA world is far from unusual, but none apply them quite like this airframer does. CW had the opportunity to visit its home facility, and CW's editor-in-chief filed this intriguing story about what was on view. By Jeff Sloan 34 Inside Manufacturing: Higher Performance in Precast Concrete with CFRP Precast concrete is made by curing concrete in a reusable mold or form in a controlled factory environment. It can be closely monitored during cure, resulting in a higher quality product than can be provided when concrete is poured and cured in job-specific forms at construction sites. C-GRID carbon fiber-reinforced polymer trusses used in the CarbonCast- brand precast concrete wall system are raising the bar, cutting building construction time, cost, complexity and carbon footprint in energy-efficient urban student housing.
