Fig. 4: Effects of CO2 on the mechanical properties of elastomers.
From: Elastomers mechanically reinforced and toughened with CO2 gas
a Effects of different gases on the fracture energies of elastomers. For CL–M5 and CL–D9, N2/CO2 mixed gases were also used. Fracture energies were determined by tearing tests for trouser-shaped test pieces40. b Relationship between the fracture energy and shear loss modulus (Gʺ) of elastomers at 25 °C. c Fracture energy against GʺAint (Aint = 4πR12×ND). d Tensile testing of elastomers measured at 26 °C ± 1 °C in N2, air, and CO2 gases. The strain rate was 0.09 s−1. e Compression tests for CL–M5 measured at 26 °C ± 1 °C in N2 and CO2 gases. The strain rate was 0.03 s−1.
