However the experimentally measured modulus values are much lower than the values predicted by these equations for the aspect ratios in the range of 100–1000 as shown in Figure 15.15. This could be due to the imperfect bonding between the clay surface and polymer matrix which reduces the reinforcing efficiency of the clay.
