Professional Development and Awareness Building for Teachers in the Area of Advanced Materials
On September 26, 2002, the National Institute of Aerospace, NIA, was created near NASA’s Langley Research Center in Hampton, VA as a result of a winning proposal submitted from the AIAA and a 6-university team in response to a broad agency announcement. Our proposal emphasized these four imperatives to:
• Conduct leading edge aerospace & atmospheric science research and develop revolutionary new technologies by creating innovative, collaborative, synergistic partnerships among NASA’s Langley Research Center, academia, and industry, • Provide comprehensive graduate and continuing education in science and engineering by using both a local campus and exploiting innovative distance-learning concepts, • Incubate and stimulate the commercialization of new intellectual property developed through the Institute's activities, including radical ideas and disruptive technologies, and • Promote aerospace science and engineering and provide outreach to the region and nation.
As part of the fourth imperative, we specifically proposed to develop and conduct summer workshops for grade 6-12 teachers.
The goal of our workshops was to provide brief yet thoughtful introduction to some of the important scientific and engineering challenges involved in NASA’s complex missions. One of these challenges included the development of lightweight, high strength composite materials. This paper describes the experiences teachers gained in the area of advanced composite materials as part of the 2003, 2004, and 2005 workshops.
Participation in the workshops, limited by space, schedule, and cost considerations, was limited to 26, including 2 supervisors, in 2003; 20 in 2004; and 19 in 2005. In all three workshops, teachers used the Vacuum Assisted Resin Transfer Molding process (VARTM) to fabricate woven polymeric composite panels. A mold was loaded with the preform made of reinforcement material. The mold was then closed and resin was introduced and flowed along the transverse direction of the preform.
Once cured, the teachers were able to cut tensile coupons and to evaluate the quality and consistency of the samples of the VARTM manufactured panels. The teachers actually produced four large panels. Twenty tensile coupons were cut from each panel and coupon tests enabled teachers to compare spatial variation of properties within a given panel produced during by the manufacturing process. In addition to the experience in processing, tensile testing and statistical analysis, the teachers became aware of cost considerations in manufacturing, since they were required to track materials and labor costs during the experimentation.
