...The authors found out that the fracture stress of flat graphene is 97.5 GPa, while that of wrinkled graphene is around 60 GPa at room temperature, as a result of the softening of the material due to the presence of the wrinkles....

...In an example of the application of the modified rule of mixtures (MROM), an epoxy resin was reinforced by GO nanoplatelets and the effective modulus of the GO was found to be equal to 90 GPa, while the particle modulus was found to be equal to 169 GPa assuming gl ’ 1 [324]....

...Moreover, it is obvious that there is a large number of works in soft matrices with stiffness in the order of a fewMPa (elastomers) and stiffer matrices (thermoplastics-thermosets), while the category of materials with average stiffness ranging from 10 MPa to 1 GPa (e.g. thermoplastic elastomers) seems underrepresented....

...This value can be compared with the accepted modulus value of 200–250 GPa [4,154] and the discrepancy may be due the presence of short flakes, so that gl < 1....
