Watri (2010) examined the addition of chopped strand glass fiber with 1%, 1.5%, and 2% concentration in heat-polymerized acrylic resins (QC 20), reported that there was an increased in impact strength
and transverse strength with the addition of 1% glass fiber while the addition of 2% glass fiber can reduce the transverse strength of heat-polymerized denture base material.
Specimens were tested for impact strength
on Hounsfield balanced pendulum impact machine (England).
For each set of samples, we determined the mean value of impact strength
as well as specifying a confidence interval by means of Student's t distribution for the confidence level of 1- [alpha] = 0.95.
As there are many adhesive materials now available in market, but the choice of material with higher impact strength
and which can retain the reattached fractured tooth fragment for longer time is still not clear.
The flexural strength was measured by using universal testing machine (Instron-3366) with a strain rate 5mm/min and impact strength
by balanced impact testing machine (Hounsfield balanced impact testing apparatus (Tensometer Ltd.
In order to assess the impact strength
of naturally occurring fiber, this work deals with the impact test of Bertam fiber gotten from fronds, sieved to particle size.

of experimental pellets of Particle Board
The notched impact strengths
of the 80/20 PP/POE blend samples taken from four positions were tested at 23 and -20[degrees]C and the results are shown in Fig.
Aaron Lin, Business development manager at XANTAR LDS at Mitsubishi Engineering-Plastics, said: "This innovative coloured grade has proved a key discriminating factor in the realisation of thin integrated GSM antennas in ultra-thin and light-weight notebooks and tablets, combining excellent impact strength
with state-of-the-art flammability and first-rate plating performance."
New alloys, both hypoeutectic and hypereutectic, then were prepared to explore the influence of alloy composition, primarily the aluminum content, on fluidity and impact strength
CHEMTHANE 2260 has impact strength
expressed as Shore D hardness of 76.
Bischof and Klein have used metallocene catalyzed polymers to produce a 140 micron co-extruded film with high impact strength
, exceptional sealability and enhanced optical properties.
