The influence of pins on the compression and tensile strength of a composite resin was measured.
Compression strength was measured in cylindrical samples 8 mm long and 4 mm in diameter, using different size threaded stainless steel pins. The tensile strength was determined by compression along the diameter of cylindrical samples containing different sizes and orientations of threaded stainless steel pins.
The conventional dumbbell tensile strength was measured by pulling the mounted specimens in the direction of their long axis, using non-threaded pins.
These tests demonstrated that the compressive strength of the composite was increased 10 percent when the large size diameter threaded pin was used. The diametral compression showed no significant increase or decrease of the tensile strength, while the conventional dumbbell test demonstrated an increase of 40 percent in tensile strength in the samples containing the non-threaded pins.
