Abstract

(1) Smart Adhesively Bonded High Performance Joint for Composite Structures
Principle Investigator: Dr. Guoqiang Li
Co-principle Investigator: Dr. Su-Seng Pang

This NASA Research/Education Project, "Smart Adhesively Bonded High Performance Joint for Composite Structures" brings together researchers from Louisiana State University (LSU) and Southern University in Baton Rouge (SU), supported by NASA researchers at a variety of centers and industries, for a collaborative project that will provide exciting new results for NASA along with developing an important new capability in Louisiana. The goal of this project is to provide NASA with durable, reliable, and intelligent adhesively bonded composite joints, and enhance NASA-missions as well as related research infrastructure and workforce training in Louisiana. In this presentation, both research and educational accomplishments will be discussed, including (1) Fracture of adhesive bonding in adhesively bonded joint has been better understood. Analytical modeling has also been developed to decouple the Mode I fracture from Mode II fracture for adhesively bonded dissimilar substrates. (2) The effect of externally bonded piezoelectric layer on counterbalancing the bending load in adhesively bonded joints has been evaluated. Parameters affecting the efficiency have been investigated and analytical modeling based on elementary mechanics of materials has been developed, which can be used to optimize the piezoelectric layer. (3) A bio-mimetic self-healing scheme has been proposed and has been used in adhesively bonded joint. It is found that macroscopic cracks in the adhesive layer can be repeatedly healed and the healing efficiency has been well maintained after up to five rounds of fracture/healing cycles. (4) The research infrastructure at both LSU and SU has been significantly enhanced, as evidenced by the growth and mature of the research team, enhancement of new equipment and facilities, and graduation of Ph.D., M.S., and undergraduate students. The results from this project have been widely disseminated as evidenced by numerous publications in high visibility archival journals, conference proceedings/presentations, and invited talks.

(2) Responsibilities of Engineers to Society and the US ABET/SACS Accreditation Processes

The engineer today needs to be well-grounded with sound technical knowledge and understanding and is a hands-on problem solver, a skilled communicator, adept at teamwork and possessing strong work ethic and leadership qualities. He/she will be a critical and holistic thinker and a life-long learner, be entrepreneurial in spirit, have greater awareness of national and global implications of issues such as environment and sustainability and remain engaged with community and society. The impact and effectiveness of engineers will be recognized by: (1) Solving problems for the benefit of the society and to meet society's future needs; (2) Dealing with critical problems that affect and improve human lives through research and innovation; and (3) Expanding and diversifying the economy through outreach and entrepreneurial activities. In addition to the discussion of today engineers' responsibilities to society, two accreditation programs in the U.S. will also be discussed – ABET and SACS. Accreditation Board for Engineering and Technology (ABET) was established in 1932. It ensures that graduates from each engineer program will have some minimal skill set for entry into the workforce or for future education. The current criteria stress continuous improvement, and accounts for specific missions and goals of the individual institutions and programs. While ABET focuses on undergraduate programs, Southern Association of Colleges and Schools Council on Accreditation and School Improvement (SACS CASI) will examine both undergraduate and graduate programs. For both accreditation processes, department, college, and university will undertake exhaustive self-studies involving the participation of faculty, administrators, staff, students, and administrators. Accreditation is important because: (i) It helps students choose quality college programs; (ii) It enables employers to recruit graduates they know are well-prepared; (iii) It is used by registration, licensure, and certification boards to screen applicants; and (iv) It gives colleges and universities a structured mechanism to assess, evaluate, and improve the quality of their programs. The speaker would like to share his experience in both ABET and SACS accreditation processes.

Biography

Dr. Su-Seng Pang was born in Macau. He received his B.S. degree in Mechanical Engineering from National Taiwan University and his Ph.D. degree in Mechanical Engineering from U.C. Berkeley. Currently, he is the Associate Vice Chancellor for Strategic Initiatives and Jack Holmes Distinguished Professor of Mechanical Engineering at Louisiana State University (LSU). Dr. Pang is a Fellow of three professional societies: American Society of Mechanical Engineers (ASME), Society of Plastics Engineers (SPE), and American Association for the Advancement of Science (AAAS). In 2006, he was bestowed an Honorary Doctorate (Doctor of Science honoris causa) from the University of Macau, China. He is a recognized expert in the composite materials research field as reflected in his over 200 journal papers/conference proceedings in this area. He has been the Principal Investigator (PI)/Co-PI of over 100 projects funded by NSF, NASA, Navy, Army, Air Force, Department of Energy, and various industries. Since 1996, Dr. Pang has received 34 U.S. national/regional awards in research and education, including: AAAS National Mentor Award; Presidential Award for Mentoring (at the White House); Tibbetts Award for SBIR Model of Excellence (at the White House); ACAP Distinguished Achievement Award; AACP Outstanding Achievement Award; Minority Access National Faculty/Administrator Role Model Award; ASME International Board on Minorities and Women Award; Carnegie/CASE Louisiana Professor of the Year; ASEE National Minorities in Engineering Award; etc.
