CCM Accomplishments to be Showcased at SAMPE 2005

The SAMPE 2005 Symposium & Exhibition will provide CCM with an ideal venue to showcase its recent accomplishments. The event will be held in Long Beach, CA, from May 1–5. CCM researchers are presenting more than 15 papers over a wide range of topics at this year’s conference. Visitors to CCM's booth will learn about developments in software and re-engineering capabilities, efforts in elevated-temperature VARTM, and continuing improvements in manufacturing sensing and control.

“Our high level of interaction with industry is a major factor in our continued progress in research and technology transfer,” says Center Director Jack Gillespie. “We offer our consortium members the opportunity to participate in collaborative research with us, and we continually apprise them of progress on large sponsored programs as well as individual projects. The SAMPE Symposium will provide us with an excellent opportunity to demonstrate the many benefits of consortium membership to potential new members.” From fiscal year 2004 to present, 62 companies have benefited from consortium membership.

In addition to research findings, the Center's booth will feature demonstrations of software for advanced design and analysis of composite structures. Developed at the Center over the past several years, these powerful tools have recently been upgraded and packaged as a new Composite Design Software (CDS) suite. The tools are available to government sponsors and members of the industrial consortium. Click here to download new CCM CDS TechBrief

With education an important component of CCM's mission, the activities of the SAMPE chapter at Delaware will also be showcased at the event. Two graduate student members, Solange Amouroux and Vahik Krikorian, have received SAMPE-sponsored trips to compete as finalists in the student symposium, to be held on Tuesday, May 3rd.

Other members of the SAMPE-UD chapter attending the conference include Valentin Neascu and Xiao Gao. Gao was the first-place winner at last year's Student Symposium; as winner, she received a society-sponsored trip to Paris to present her research at the SAMPE Europe 26th International Conference and Forums.

In addition to the exhibit, the findings of CCM's collaborative research programs will be highlighted in eighteen papers presented at technical sessions. The following provides the title, authors, and session date, time, and topic for each paper. Exact presentation times should be checked on the program.

Graduate Student Receives Adhesion Society Award Xiao Gao, a PhD candidate working at CCM, has been awarded a Peebles Award for Graduate Student Research in Adhesion Science, which provides partial support to attend the annual meeting of the Adhesion Society. In addition to this support, registration fees for the short course and the meeting are waived for the Peebles Award winners. The selection of awardees is based upon a short paper, submitted by the student, covering his/her own work to date. The title of Gao's paper is "A Study of the Mechanical Interlocking Effect on Polymer Composite Properties."

Last year Xiao Gao took first place in the Ph.D. portion of the SAMPE Graduate/Senior Student Award and Symposium Competition in Long Beach, CA. Gao served as the president of the SAMPE-UD student chapter for 2003-2004. Jack Gillespie is Xiao Gao's advisor in research on interface mechanics including the microdroplet and other tests under the Composite Materials Research Program funded by the Army Research Laboratory.
