Getting part dimensions right in composites molding
Guest columnists Dr. Göran Fernlund (left) and Dr. Anoush Poursartip (right) of Convergent Manufacturing Technologies (Vancouver, BC, Canada) argue that today's CAD design and process simulation software can construct a "multi-physic process model" accurate enough for reliable dimensional management.

Can IACMI propel us out of adolescence, into adulthood?
On Jan. 9, the US Department of Energy (DoE) announced that it will add US$70 million to the US$189 million already committed to the University of Tennessee’s Institute for Advanced Composites Manufacturing Innovation (IACMI) for composites R&D. CW's editor-in-chief Jeff Sloan asks, "What will come of this investment?"

Supply and demand: Advanced fibers (2015)
Demand for advanced fiber, virgin and reclaimed, is on an upswing after a dip during the recent recession. Fiber suppliers are gearing up to meet an expected increase in demand as manufacturers in a number of composites end-markets scale up or start up part development and production programs.

Tooling (2015)
Composite parts are formed in molds, also known as tools. Tools can be made from virtually any material. The material type, shape and complexity depend upon the part and length of production run. Here's a short summary of the issues involved in electing and making tools.

Fiber reinforcement forms
Fibers used to reinforce composites are supplied directly by fiber manufacturers and indirectly by converters in a number of different forms, which vary depending on the application. Here's a guide to what's available.
