The Mechanical Engineering Department is pleased to announce the first in it's Fall 2012 SEMINAR series.

November 8, 2012 at 11am – 12pm in the Textile Building, Room 101E (College of Engineering Conference Room)

SPEAKER: Dr. John Rice

TOPIC: Improving Composite Materials by Z-Axis Flocking Reinforcement

ABSTRACT is: Organic Polymer Engineered Composite (OPEC) materials based on layered fabrics such as fiberglass or carbon composites are widely used throughout the world because they possess many advantageous property and processing features. OPEC laminar composite materials are used in a wide variety of important commercial and military applications where a high strength to weight ratio is required. Aircraft, marine structures and boat hulls, military vehicle and body armor, and wind turbine blades are some notable applications. However, current fabricated laminar composites demonstrate relatively poor fracture toughness, which results in delamination or crack growth between layers. This is a critical structural flaw that can lead to material reliability problems, including catastrophic failure. This is because layered OPECs have little or no fiber reinforcement in the thickness or “Z” direction. Applying UMD’s developed technology can dramatically improved the fracture toughness of fabric layered OPEC materials without decreasing their in-plane material properties. Tests have shown that the reinforced composites are up to 7 times tougher. In addition, other materials properties can be improved with this technology including through thickness thermal and electrical conductivity.

All are welcome. First year MNE MS students are required to attend; all other MNE students are encouraged to attend.

Light refreshments will be served.
