Effects of various temperatures on the mechanical strength of GFRP box profiles

In this study, tensile and compressive samples from GFRP box profiles measuring 74 × 74 × 4 mm produced with the pultrusion method were tested at different temperatures. Samples were tested with tensile and compressive tests at 13 different temperatures: −50, −25, −10, 0, +10, +25, +50, +75, +100, +125, +150, +175, +200 in severe cold and high temperatures under the influence of both tensile and compressive stress and losses of strength for GFRP profiles were determined.
