A thermoplastic composite tendon testing apparatus according to any one of claims 1 to 5, further comprising a pair of support plates, a third elongate hole being provided in a pair of the support plates, the guide wheel being disposed between a pair of the support plates, and the shaft ends of the guide wheel being disposed through the third elongate hole and being fixable by a fastener.

10. A method for testing thermoplastic composite ribs, the method comprising the steps of:

Passing a bar through the first slot of the side plate to fix the first end of the bar to the angle adjustment assembly;

bypassing the rib material around a guide wheel, and enabling one side of the guide wheel to prop against the rib material so as to enable the rib material to form a preset bending angle at the guide wheel;

Fixing the second end of the tendon to a tensioning assembly;

And starting a stretching assembly to apply load to the reinforcement.
