Laboratory development and tensile testing of grapite/glass/epoxy hybrid composite materials.
laboratorydevelo00linn.pdf (3.054Mb)Abstract
Most advanced composite materials in use today consist
of a single type of reinforcing fiber embedded in a matrix.
There are possible advantages, however, in a system which
used multiple types of reinforcing fibers. Such a material
is called a "hybrid" or "mixed modulus" composite.
This thesis describes the establishment of a composites
laboratory facility at the Naval Postgraduate School and the
development of manufacturing techniques to produce high-quality
hybrid composite specimens for testing. Glass/graphite/
epoxy hybrid specimens manufactured in this laboratory
were tested to determine the dependence of material properties
on the relative orientations of the fibers. Results of
the test program were compared with predictions made using
classical laminate theory.
