CMML publishes a series of papers on the high
strain rate response of metal matrix composites
A series of three papers appear in the
February 2011 issue of
JOM, a journal published by The Minerals,
Metals and Materials Society. The first paper
presents results on
magnesium alloy/fly ash
composites, the second paper studies
aluminum alloy/fly ash composites and the
third paper presents a
review of the present state of knowledge on
metal matrix syntactic foams. A Ph.D. students
at CMML Dung Luong is the lead researchers in
this study, which is conducted in collaboration
with
Dr. P. K. Rohatgi of University of
Wisconsin. The
review article is selected for open access
through TMS website.
The journal featured an image from one of the
papers on the cover page of the issue.

Nguyen Nguyen, a
Ph.D. candidate at CMML, wins American Society
for Composites Ph.D. Scholarship award
Nguyen is one of the two winners of the American
Society for Composites Ph.D. scholarship award
2008. Each year the society provides these
awards to recognize outstanding research in the
composite materials related area. His work on
development of fiber-optic sensors and their
applications in structural health monitoring of
composite materials has potential for a wide
ranging applications. He was presented this
award during the society's annual meeting in
Memphis from September 9-11, 2008. More
information on this award can be found

New Functionally
Graded Composite designed at CMML
Two recent papers demonstrate superiority of
functionally graded syntactic foams (FGSFs)
designed by CMML to be higher damage tolerant
and energy absorbent compared to the existing
functionally graded and plain syntactic foams.
The
First paper authored by Dr. Nikhil Gupta
proposes the new FGSF structure. The
Second paper presents results of an
extensive experimental scheme that compares the
compressive properties of traditional FGSFs
created by a volume fraction gradient in their
structure and the new types of FGSFs based on
the microballoon wall thickness approach. The
new syntactic foams designed by CMML are found
to have 200-500% higher energy absorption
capabilities under compression.
