CompositesWorld conference emphasizes information for composites rookies, veterans

The CompositesWorld 2012: Materials, Markets, Manufacturing conference, co-located with SAMPE Tech 2012 in Charleston, S.C., is scheduled for Oct. 22-23 and emphasizes composites information for new and experienced composites professionals.

The CompositesWorld 2012: Materials, Markets, Manufacturing conference, co-located with SAMPE Tech 2012 (Charleston, S.C.) and scheduled for Oct. 22-23, features speakers and presentations designed to cater to the needs of composites professionals new to the industry, as well as those who are more familiar with composite materials and processes.

Among the speakers presenting is David Maass of Danobat FIBRA, whose presentation will focus on the development of automated dry fiber reinforcement placement. Historically, this task has largely been performed manually, but with very high volume production applications such as wind turbine blade manufacturing, there is very strong interest in automating these processes. Recently, fully automated and full scale equipment has been developed that achieves many of these objectives, and achieves floor-to-floor laydown rates that are two to three orders of magnitude higher than currently seen in automated fiber placement (AFP) of prepreg material used in commercial and military aerospace. This presentation describes these capabilities as developed for very large parts made at very high rates in the wind blade industry.

Bill Hasenjaeger, product marketing manager at CGTech (Irvine, Calif., USA) will discuss the programming of automated fiber placement (AFP) and automated tape laying (ATL) technology. Now that AFP technology has been proven for a variety of production parts, more companies are considering AFP equipment to replace their existing processes. But before they do, it is important to learn how AFP’s capabilities and limitations affect their ability to meet design and manufacturing requirements. This presentation discusses the interaction between part programming and machine functionality, and how it is affected by part geometry, ply boundary shapes, lay-down path trajectory, material limits, and the physical behavior of the machine, the fiber placement head and mechanics of the layup process. Using practical experience gained during AFP machine and process development for a variety of production parts, the presentation describes the challenges and rewards of using AFP for composite part production.
