Structures & composites

Engineered advanced materials and adaptive structures for sustainable terrestrial and space travel, security and habitation.

The widespread adoption of composites - combined with advances in additive manufacturing, robotics and automation - has expanded our capacity to manufacture new forms and build unusual flight structures. Our faculty explore new designs, tests, and manufacturing methods, looking at how novel materials are performing across the industry. Current research includes design of engineered materials systems (e.g. nanocomposites and metamaterials), structural design, material characterization, non-destructive testing and evaluation, certification and structural health monitoring. In these activities, state of the art computational modeling methods are utilized and new methodologies are developed.

Undergraduate students have the opportunity to design, build, and fly new aircraft concepts in our senior-level Aircraft Design Capstone. The new capstone design teams includes personnel from industry and allow students to work on a variety of structural concepts that impact spacecraft, aircraft and unmanned aerial systems. The teams make use of our on-site machine shop, composite lab, and 3D fabrication facility. Graduate students work closely with prominent faculty and collaborative industry partners on contemporary cutting-edge research problems.

In Memoriam: Professor Kuen Y. Lin

We mourn the passing of Professor Kuen Y. Lin on January 19, 2017. Professor Lin served on the A&A faculty for 33 years as a dedicated professor, mentor and colleague. After receiving his bachelor’s degree from National Taiwan University and master’s and doctoral degrees in Aeronautics and Astronautics from MIT, Professor Lin spent six years in industry, working for Deere & Co. and The Boeing Company. Professor Lin was an expert in the areas of composite materials, finite element methods, and fracture mechanics, and co-creator of the Mar-Lin Fracture Model, which is used by the aerospace industry for the damage tolerant design of composite aircraft structures. He also developed a singular hybrid finite element method for the accurate analysis of bi-material fracture problems. His recent research efforts have direct applications to the critical technologies needed in developing the next generation of aerospace vehicles.

Mia Lee wins AIAA competition

Last year, Mia Lee (BS '16) received the first place award in the undergraduate category at the 2016 AIAA Region VI Student Conference for her paper titled, "Tunable Bistability of Origami-based Mechanical Metamaterials." Mia was supervised by Prof. JK Yang and mentored by Hiromi Yasuda. As an award winner, Mia was invited to participate in this year's AIAA SciTech international student competition and she again won first place, triumphing over all of the other regional conference winners.
