CCM and Mettler Toledo Launch Unique Partnership

by Diane Kukich

On Wednesday, May 21, CCM officially initiated a long-term partnership with Mettler Toledo (MT) that will provide unprecedented opportunities for training, education, and collaborative research.  A ribbon-cutting ceremony formally launched the unique university-industry affiliation between the University of Delaware and Mettler and marked the opening of a new lab at CCM equipped with state-of-the-art thermal analysis equipment and an expert in residence to support it. 

The new facility includes some $500,000 worth of equipment for thermal mechanical analysis, dynamic mechanical analysis, thermogravimetric analysis, differential scanning calorimetry, and other techniques for materials characterization. 

Speakers at the ribbon cutting included Michael J. Chajes, Dean of Engineering at UD; Jack Gillespie, CCM Director; Steve Johnson, Business Manager for Analytical Instruments at MT; and Michael Zemo , Marketing Manager at MT.

“The University of Delaware is committed to expanding university-industry partnerships,” Chajes said, “and this particular partnership is unique in the breadth of interactions that will be possible due to Mettler’s exceptional commitment.  Providing both state-of-the-art equipment and an on-site expert to assist in the use of the equipment will yield tremendous benefits to both UD and Mettler.”

According to CCM Director Jack Gillespie, the collaborative research that will be carried out in the new lab will benefit both the university and the company as new knowledge is developed about the behavior of composites and applied to the continuous improvement of research techniques and capabilities.

“Our researchers will have access to a state-of-the-art lab,” Gillespie says,” which will also serve as a showcase for Mettler and an entry port for the company into the polymers and composites market via our industrial consortium.  Because the equipment is available to other members of CCM’s consortium, the partnership has the potential to go far beyond just Mettler and CCM.   

And our future research enterprise will benefit from the new applications developed by Mettler as they work in this synergistic environment with us and our other industrial and government partners.”

Those at MT echoed Gillespie’s view of the relationship.  “We’re thrilled to enter this collaboration with CCM,” Johnson said.  “The Center has a strong reputation in composite materials and a long history of collaborating with government and industrial sponsors to conduct basic and applied research and to develop and transfer technology.  We hope to develop some exciting new solutions through this partnership.”

”We look forward to a bright future of research collaboration, development, and, most important, education,” Zemo added.

The partnership provides for maintenance, servicing, and calibration of the equipment as needed, in addition to upgrading as new technology is developed.  Dr. Steve Sauerbrunn, Technical Manager with MT, is in residence full-time at CCM to provide training and professional consultation to not only CCM researchers but also employees affiliated with consortium members.

Sauerbrunn, who holds a Ph.D. in chemistry from the University of Delaware, has more than 20 years of experience in thermal analysis of polymeric materials.  He worked for the DuPont Company, TA Instruments, and W.L. Gore before joining Mettler six years ago.

SAMPE

UD Materials Science doctoral students Amanda Lim (top)
and Gaurav Nilakantan (bottom) won first and second place, respectively, in the University Research Program, Ph.D. category paper competition.

CCM Students Win Big at National SAMPE Symposium

Several CCM affiliated students won prizes at the SAMPE University Research Symposium, held as part of the 2008 International SAMPE Symposium & Exposition in Long Beach, California, from May 18-22.

Amanda Lim and Gaurav Nilakantan won first and second place, respectively, in the University Research Program, Ph.D. category paper competition. Both are Ph.D. candidates in Materials Science and Engineering.

Lim, who is advised by Prof. John W. Gillespie Jr., submitted a paper entitled “Split-Hopkinson Pressure Bar Evaluation of Viscous Fluids at High Shear Rates.”  Co-advised by Gillespie and Prof. Michael Keefe, Nilakantan submitted a paper entitled “Novel Multi-scale Modeling of the Impact of Plain Weave Fabrics Using Finite Element Analysis.”

As first-place winner, Lim will go on to the SAMPE conference in Paris next year, with her trip funded by SAMPE USA, to present her work.   The two also won cash awards.

In addition, the Center’s Wing Design Team won fifth place in the Wing Design Competition and first place in the associated Wing Design Poster competition. Advised by Prof. Suresh Advani, the team consists of Cedric Jacob (Captain), John Gangloff (Co-captain), Raymond McCauley, Nick Counts, Richie Lort, and Jason McLaughlin.  The challenge posed in this competition is to build an ultralight composite wing with the highest ratio of applied load to wing weight (P/WT) at a maximum 2.5 inch deflection.  Eighteen student teams participated in this year’s competition.

“Our students continue to excel and win awards at national events sponsored by major materials-related organizations such as SAMPE,” said Gillespie.  “It’s especially gratifying to have two of our grad students win top honors in the Ph.D. paper competition.  We’re also really proud of our team of undergrads for doing so well in the wing competition.”

CCM Hosts Baltimore/Washington SAMPE Chapter Meeting

On Wednesday, June 11, 2008, CCM hosted the Baltimore/Washington SAMPE Chapter’s final meeting of the year.  The program included a technical talk, a lab tour, and several demonstrations.  In addition to CCM students, some 15 professionals from organizations including the Army Research Lab, JHU-APL, Henkel, JEM Engineering, and Synterials attended the meeting.

“This was a great opportunity for the students to present their work and meet industry and government professionals in the field,” says Steve Scarborough, Senior R&D Engineer at ILC Dover and Second Vice Chair of the B/W Chapter.  “On the other hand, it was really good for the folks from industry to see firsthand some of the exciting materials and process work that is going on at CCM.”

Valentin Neacsu, a Ph.D. candidate in mechanical engineering, described an analytical model that accounts for capillary effects and the opposing effect of entrapped gases during the filling stage of liquid composite molding processes.

He introduced the experimental and numerical tools used to validate the analytical model and reviewed the experimental techniques employed to monitor resin flow within fiber tows (e.g., electric sensors, magnetic resonance imaging, online video monitoring of saturation index, etc.).

Four CCM students gave lab demos.  Josiah Hughes demonstrated the contact angle measurement experiment; Claire Steggall performed a resin transfer infusion using powder impregnation; Justin Alms demonstrated the Center’s IR measurement capabilities; and Amanda Lim described the shear thickening fluid body armor project and allowed participants to carry out a “stab” test.

Despite the distance that many participants traveled to attend the meeting, the consensus was that the trip was worth it.

“The Baltimore/Washington Chapter enjoys a close relationship to the University of Delaware student chapter,” says Allan Goldberg, a member of the B/W Chapter Board of Directors. “There are usually at least six student members at our professional meetings, so it is always a pleasure to ‘return the favor’ and get an update on the many exciting things being done at CCM.  The work exhibited is innovative and practical, but it is the students themselves who are most impressive.  They each gave polished presentations that would put many professionals to shame. Our members were particularly impressed with the study of capillary effects in resin infusion, the IR NDE techniques, the powder impregnation using resin transfer infusion, the viscous fluid modification of body armor, and the experiments of contact angles between fluids and barrier materials.”

“We also have developed great pride in University of Delaware student accomplishments at our Society’s international level,” he continues, “with prizes in the Wing Design competition and wins by Amanda Lim and Guarav Nilankantan in the Student Symposium. Amanda will present her paper again at our conference in Paris at next year’s JEC. We anticipate that many UD students will be key volunteers when next spring’s SAMPE Symposium is once again held in Baltimore. All-in-all, we have a very synergistic relationship that is benefitting everyone.”


CCM Group Tours Gore Facility

On April 16, 2008, UD-SAMPE sponsored a tour of the Gore Capabilities Center on Barksdale Rd. in Newark, Delaware. The tour was organized by UD-SAMPE Treasurer Josiah Hughes and hosted by Jamie Zingaro of W. L. Gore & Associates.  Zingaro detailed the history of the company, highlighting Gore’s unique business and corporate mentality. 

The Capabilities Center showcases a wide range of products, applications, and technologies from space suits and solar parachutes to heart stents and camping gear.
“I came to Delaware from the West Coast,” Hughes says, “and all I knew about Gore when I got here was that I had worn boots made from their material.  It was really interesting to see the breadth of the company’s product spectrum.”

UD-SAMPE President Amanda Lim was particularly interested in the demo of cardiovascular stents, which are used to close holes in the heart.  “The cool thing is that they can deliver the stent through a small tube and make it unfold inside the heart so it doesn’t require open-heart surgery,” she says.
Hughes took the initiative to organize the tour, because of both widespread interest in learning more about W. L. Gore & Associates, which has a number of local sites, and because his research involves a composite manufacturing membrane made by the company.
