ASTM D3916 – Tensile Testing of Glass-Fiber-Reinforced Plastic Rods

To request a quotation for any test email for a prompt reply

ASTM D3916 testing is used to determine the tensile properties of pultruded, glass-fiber-reinforced thermosetting plastic rod in diameters ranging from 3.2 mm (1.8 in.) to 25.4 mm (1 in.).

The high axial-tensile strength and the low transverse-compressive strength of pultruded rod combine to present some unique problems in determining the tensile strength of this material with conventional test grips. The high transverse-compressive forces generated in the conventional method of gripping tend to crush the rod, thereby causing premature failure.

In this test method, aluminum-alloy tabs contoured to the shape of the rod reduce the compressive forces imparted to the rod, thus overcoming the deleterious influence of conventional test grips. Touchstone has experience in utilizing the tabs in order for no premature failure to occur.

The tensile properties determined by this method may be useful for many engineering design purposes.
