Dr. John A. Cuculo
worked at duPont for 18 years and at NC State University for 30
years. He has worked with most of the thermoplastic fiber forming
polymers. He developed a process call Liquid Isothermal Bath (LIB)
which operates via a threadline control process for the production
of high-performance high-speed spun fibers. He has also studied
the dissolution of cellulose, the formation of high-performance
cellulose fibers via the solution of spinning of anisotropic solutions
in the NH3/NH4SCN solvent system and the structure/property relationships
of cellulose.

Professor
Emeritus Mansour Mohamed patented three-dimensional weaving
systems that
produce lightweight, superstrong, high-performance textile
composites that are used in cars, planes, and in the aerospace
industry. His research led him to start a company called
3TEX, which produces and markets the products. Mohamed developed
the technology nearly a decade ago for NASA's Mars Mission
Research Center at NC State. Carbon, Kevlar, fiberglass
or ceramic fibers are woven on the weft, warp, and Z (thickness)
direction, and then impregnated with polymer resin, ceramic,
or metal and hardened to produce stable, preformed structures
that can be steel. Mohamed continues to explore an array
of applications for the process, and his latest patent for
five-dimensional weaving technology adds strength to its
end products. Recently, he collaborated with his NC State
colleagues in architecture and civil engineering to use
textile composites to reinforce concrete for building and
infrastructure material.

3-D
woven fibers remain straight in each axis, reducing
the fiber stress damage that can occur with other
weaving methods.

3-TEX
carbon preform composites are stronger than steel
and lighter than aluminum.

The
office of the director of NC State's Office of
Technology Transfer and Industry Research (OTTIR)
has played a major supporting role in launching
3TEX. Mark Crowell, director of OTTIR, says, "the
start-up venture underscores NC State's commitment
to help move important discoveries from the laboratory
to the marketplace." NC State is commited to securing
patents to protect intellectual properties and
to evaluate the commercial potential of the technology.
Robert Pozner, associate director of OTTIR, notes
that feedback has been positive. In fact, a German
automotive company that purchased one of Mohamed's
early three-dimensional weaving machines for research
purposes has demonstrated that composites
out-perform aluminum in strength and rigidity.
The company's findings support Mohamed and his
colleagues' research that anything that can be
made with metal can be made with fiber-reinforced
composites--from engine parts to oil rigs to heat
shields. |

Improvements
in process for preparing water-dispersible polyester fiber
|
U.S.
Patent Number 5,145,622 |
|
Many
millions of pounds of polyster are produced worldwide using
the technology in this patent. Commercial plants are currently
located in North and South Carolina, People's Republic of
China, India, Turkey, Russia, and other site's throughout
the world. The advantages are extremely low investment, internal
waste recycling leads to high yields and low environmental
impact, and low heavy-metal catalyst usage. |
