2.3.1. Curing Characterization

Curing characteristics were measured on the Premier MDR moving die rheometer from Monsanto Company (Dayton, Ohio, USA) at a constant temperature of 160 ◦C. Scorch (*ts*1) and optimum cure (*t*90) times were evaluated by these measurements.

Consequently, compression molding in a hydraulic press at 20 MPa and 160 ◦C was used for the test sheet preparation. The samples sheets (150 mm × 150 mm) for mechanical tests measured 1 and 2 mm in thickness, cylinders measured 10, 15, 20, and 80 mm in diameter for vibration tests, and cylinders measured 20 and 100 mm in diameter for cyclic pressure tests. The samples measuring up to 2 mm in thickness were molded over the given time period, which is given by the time *t*90. The curing time for samples thicker than 2 mm was calculated as the value of time *t*90 with the addition of 1 min per each 1 mm of sample thickness.
