Resins for the Fast Zone
An automotive supplier must have the ability to produce a composite part in a minute, or at least in minutes — not hours or days, the norm for composites in most other industries. Meeting that part-per-minutes goal is a huge hurdle that a few composite fabricators have cleared, and many more are involved in development efforts, with OEM or Tier partners. ÂÌñÏ×ÆÞ reviews how resin suppliers have evolved their products for this critical market.

Optimum unidirectional compression testing of composites
Dr. Daniel O. Adams, a professor of mechanical engineering, the director of the Composite Mechanics Laboratory at the University of Utah, and VP of Wyoming Test Fixtures Inc. (Salt Lake City, UT, US) discusses the complex relationship between composite tensile and compressive properties, why that makes it necessary to perform both tension and compression testing, and how best to perform the latter.

Workforce development: Let's start in high school
CW Editor-in-Chief Jeff Sloan says one concern at the otherwise positive initial membership meeting of the new Institute for Advanced Composites Manufacturing Innovation (IACMI) was that the composites industry is quickly losing knowledge, as old-timers retire, that is not so easily replaced. Here's his prescription.

Thermosets vs. thermoplastics: Is the battle over?
Dale Brosius, the chief commercialization officer for the Institute for Advanced Composites Manufacturing Innovation (IACMI) and a regular CW columnist, sees a shift in the industry from infighting between proponents of thermoset and thermoplastic composites to a healthier competitive atmosphere that serves to make composites overall more competitive with legacy materials.
