... resistance values, although such materials would have lower stiffness. Figure 1 shows the variation of notched impact with flexural modulus for a typical range of acrylonitrile-butadiene-styrene (ABS) resins. Some stiffness can be recovered by adding fibrous reinforcement, but the reinforcement can also...
