Shared composite material property databases
For more than a decade, NASA, FAA, industry and academia have been working toward the goal of creating a centralized composite material property database similar to that for metals. Their efforts, while productive, have not come with the war-like strength that the standardization of metals did. The composites industry is guided by Composite Materials Handbook 17 or CMH-17 (formerly known as MIL-HDBK-17).

Polyurethane long fiber technology (LFT) replaces wood in spa surround
To many consumers, the thought of a relaxing soak in a hot tub is mighty appealing — but the thought of spa maintenance, particularly replacing rotted wood in the spa's cabinet-like enclosure, probably isn't. For spa manufacturer Clearwater Spas (Woodinville, Wash.), that reality and the fact that building decorativ
