Figure 2. Mechanical properties of polymer composite fibres.

Figure 2

(a) Stress–strain curves of hybrid (1:1 weight fraction of RGOF to SWNT, red line), SWNT/PVA (green line) and RGOF/PVA (blue line) composite fibres. (b,c) Elastic modulus (circles), tensile strength (squares) (b) and toughness (c) values of fibres with different weight percents of RGOF in total carbon nanomaterials. (d) Comparison of toughnesses of prior-art materials1,6,13,16,18. Error bars in b, c represent the minimum and maximum values obtained from five independent experiments.
