Tensilsaw for Fiber Reinforced Plastic Strips

July 17, 2017

New on YouTube: the video demonstration of the Tensilsaw being used to prepare strips of fiber reinforced plastic from 12″ square plaques.  The material saws quickly and easily, with minimal operator training.

After t

he strips have been prepared, they can be used for flexural testing, or any test requiring a straight strip.  Alternatively, and frequently, the Tensilsaw is used to cut blanks for insertion into the template, to be cut using the Tensilkut II or Tensilkut I into tensile bars.  A common specimen to be prepared in this manner is ASTM D638, or ASTM D695 tensile bars.  Another use for such strips would be for insertion into the V-Mill template, to be notched for Iosipescu shear testing in accordance with ASTM D7078 or ASTM D5379.

Iosipescu Shear Test Sample Preparation

November 14, 2013

One of the biggest challenges in preparation of the V notches for shear testing in accordance with ASTM D5379 or ASTM D7078 is the perfect alignment of the notches on opposite edges of the prepared specimen blank.  Tensilkut’s V-Mill is designed specifically to address that issue.

The machine is shipped adjusted for correct placement of the notch within the blank.  The specimen blank is clamped within a two sided template and not removed until the notches are complete.  A series of light passes ensure that the notches are evenly cut, and our specially designed cutter creates the 90 degree notch with a perfect radius at its base.

V-Mill Gauge

The V-Mill contains a precision height gauge which can be used to check the placement of the cutter; this would most often be done when the cutter is replaced.  The height gauge ensures that the placement of the notches is correctly centered along the length of the specimen.
