ATP FOCUSED PROGRAM:
Manufacturing Composite Structures
FY 1994 NIST Funding: $25 million
Total FY 1994-98 NIST Funding: $160 million
Potential for U.S. Economic Benefit
Doing more with less is a formula for good business. It also
expresses the promise of composite materials whose engineering
performance can exceed that of traditional materials while reducing
the weight, maintenance expenses, and operating costs of cars,
planes, missiles, spacecraft, bridges, offshore oil rigs, and other
structures. So far, however, the driving force to develop advanced
composites which typically combine the lightness of a polymer with
the stiffness and strength of glass or ceramic reinforcing fibers
has been the additional performance that the materials allow and
not their cost of manufacture.
A new five-year program in Manufacturing Composite Structures aims
to help U.S. companies develop the technical capability for
producing vast amounts of affordable high-performance composites
for large-scale commercial applications. With that capability in
place after five years, new annual markets in the range of tens of
billions of dollars could begin opening to U.S. companies,
according to industry projections. For example, a team of companies
projects that 184 million pounds (83 million kilograms) of
composites could be introduced in deep-sea drilling platforms
totaling $2.9 billion over the next 10 years. If composites
captured even 5 percent of the $130 billion needed to bring 230,000
of the nation's bridges up to structural and functional snuff, the
market would total over $6 billion. Auto manufacturers estimate
that composites orders in the $20 billion range are possible, in
this case for building lighter weight vehicles that consume less
fuel. The program's budget will begin with $25 million in FY 1994
with a total of $160 million during the program's five years.
Technology Challenge
Methods of manufacturing composites now are too labor intensive or
too product specific to work smoothly in larger volume commercial
settings such as auto manufacturing and bridge building. The new
five-year ATP program proposes to turn the table on that situation.
By the end of the program, participants should be able to
demonstrate cost-effective manufacturing processes for making large
composite structures for several classes of applications and be in
a position to develop and adapt those processes for
commercial-scale production.
Among the major technical goals is the automation of processes for
creating complicated three-dimensional arrangements and weaves of
the reinforcing fibers. Another goal is to integrate design and
simulation tools for predicting the properties and reliability of
the composites during their service lifetimes. Also, the program
agenda emphasizes development of sensor systems, some built
directly into the composite structures where they will monitor the
health of the composites throughout their manufacturing phases and
lifetimes. These can help certify the materials reliability for
engineers and builders who are more familiar and comfortable with
traditional materials. These and other advances also should lower
the cost of designing with composites since fewer prototypes will
have to be built and tested.
Industry Commitment
A broad cross section of materials suppliers, component
manufacturers, and end users who would design lighter and more
efficient cars and buses, more capable and durable bridges, and
cheaper oil-drilling platforms that could open less accessible oil
sources under deeper waters have helped articulate the new ATP
program and have expressed willingness to share its cost. All of
the goals and benchmarks for this program were derived from
industry-produced white papers and meetings with representatives
from the composites R&D community.
Significance of ATP Funds
The ATP focused program is the means to trigger expansion of
advanced composites beyond military applications and small
commercial niches, such as sports equipment, into much larger
commercial markets. In FY 1994, $207 million of composites research
will be funded from nine different federal sources, but only a
small portion is for technology development aimed at commercial
markets. Most federal support, which accounts for more than half of
all R&D in advanced polymer matrix composites, focuses on aerospace
and military structures. That, together with the inherent risk of
developing new materials in markets where traditional materials
have been used for decades, has kept private investment in
non-military applications to a trickle. Moreover, efforts to build
new markets for composites have been checked by industrial
downsizing and rollbacks in research that would yield important
information about the composites performance encouraging them to
select traditional materials over new ones. The ATP effort will
enable U.S. industry to develop advanced composites whose
technological advantages have been demonstrated well in military
and aerospace applications, into a sound and expansive business for
known commercial markets where the cost of these materials has kept
them out of reach.
