RESUMO
With respect to the elasticity module, it was observed that the incorporation of fiberglass to acrylic resin makes the test bodies more rigid, decreasing their rupture lengthening. The presence of fibers confers on the material a greater capacity of elastic recovery.

Traction trials were carried out on acrylic resin test bodies for denture frames reinforced with cut and ground fiberglass, to determine rupture tension. The results demonstrated that: 1--Cut fibers tend to increase the resistance of acrylic to traction forces, and the increase in load percentage of these fibers also increase resistance. 2--This increase was more marked when treatment with SILANE A 174 was combined with the use of cut fibers, at all concentrations tested.

The rupture lengthening test demonstrated the addition of fiberglass to acrylic resin tends to make the test bodies more rigid, making them fracture with a shorter lengthening than unloaded resin. The greatest rigidity was observed with a 20% load.
