1-in. in thickness. Widely used in electronic and optical
components, it is optically clear, can transmit light from
220-2500 µm, and has a refraction index of 1.45. As is
typical for silicones, it is very flexible and can withstand
thermal cycling and shock. The system is highly resist-
ant to water and is serviceable over the -65° to 400°F
temperature range. .
Hitachi Ltd., Tarrytown, N.Y., announces a new computer-
controlled tri-axial material fatigue testing machine that
emulates complex stress conditions that occur during op-
eration of mechanical structures, such as those used in
construction machinery and renewable energy facilities.
Surface stress on mechanical structures is described as
in-plane structural element deformations in the transverse,
longitudinal, and diagonal directions. However, as con-
ventional material fatigue testing machines are only able
to apply two of these deformations to a test specimen,
accurate reproduction of complex stress conditions is dif-
ficult. The new tri-axial testing machine is able to emulate
stress states working on surfaces of mechanical struc-
tures by applying three independent loads to the test
specimen using actuators that apply loads in the 0°, 45°,
and 95° directions. .
PlastiComp Inc., Winona, Minn., introduces a line of
basalt fiber reinforced LFT composites. These new
long fiber products offer a significant
increase in performance over short
basalt fiber filled materials and are
available in multiple resin matrices
with 30-60% by weight fiber load-
ings. Derived from volcanic rock, the
beneficial characteristics of basalt
fiber include excellent corrosion resistance, high abra-
sion resistance, and inherent fire resistance. Basalt fiber
is known for retaining its performance at cold tempera-
tures and for not being degraded by UV or electromag-
netic radiation. It is well suited for applications in marine
settings, concrete contact, and underground environ-
ments. .
A new brochure from Malvern Instruments Inc., Westbor-
ough, Mass., details the company’s range of detectors
for gel permeation/size exclusion chromatography
(GPC/SEC). Available as standalone units, or as part of a
fully integrated Viscotek multi-detection
GPC/SEC system, the detectors provide highly
accurate analysis of polymer and protein
macromolecular features and combine to offer
advanced insight into molecular structure.
GPC/SEC is a central analytical technique for
protein and polymer analysis because of its
ability to measure defining characteristics in-
cluding molecular weight, molecular weight distribution,
molecular size, and structure. The range of detectors in-
cludes light scattering, refractive index, viscometry, and
UV technology.
Shimadzu Scientific Instruments, Co-
lumbia, Md., announces four universal
testers that offer high-level control,
tight precision, and intuitive operation
for a wide variety of material testing.
The new testers come standard with
Trapexium X or Trapexium Lite X soft-
ware to gather and display data for
users in real time. Enhanced features
include: Load cells with test force ac-
curacy within ±0.5% over the range of
1/1 to 1/500 of the maximum capacity;
1 kHz sampling rate ensures no missed
strength changes; one-touch cross-
head stroke limiters allow simple ad-
justment and firm locking; faster crosshead achieves a
1600 mm/min testing speed and a 2200 mm/min return
speed (20kN frame) to save time with repetitive testing;
common joint for both tensile and compression makes it
easier to exchange jigs; and a built-in multi-purpose tray
enables placing jigs, arranging specimens, and taking
notes. .
Morgan Advanced Materials, UK, announces Certech in-
jection-molded ceramics, engineered for investment
casting of airfoils and industrial gas turbines. Cores are
available in a wide range of sizes
and complex designs for equiax,
single crystal, and directional so-
lidification casting. Critical airfoils
required to withstand the high tur-
bine inlet temperature in modern
gas turbine engines are invest-
ment cast in nickel- and cobalt-base superalloys, with
ceramic cores used to form the part’s air-cooling pas-
sages. The ability to inject around quartz rods down to
0.020-in. (0.5 mm) in diameter lets users design features
in the cooling passages that would otherwise be difficult
to form. Ceramic cores are produced using the com-
pany’s specialty P-52 and newly developed P-57 and P-
59 materials, which allow production of cores with
extremely thin (<0.012 in.) dimensions without sacrificing
stability. .
