Fig. 2. Mechanical behaviour for TBPE-6 to -9. (A) Stress–strain curves (10 mm min−1 extension rate) showing increasing Ey and σb with hard block content; (B) cyclic tensile testing (200% strain) for TBPE-7 exhibiting narrow hysteresis and (C) elastic recovery as a function of cycle number for TBPE-6 to -9; (inset) mean elastic recovery as a function of fhard.
