？ + = How to improve the tenacity of Wood Ceramic? Graphene? Source: Roy Humphreys Source: Alexander Alus

Step 1 : Preparing ingredients Graphene Oxide Reduction of Graphene Oxide (GO) (rGO)

Step 2 : Making Test Specimens 50*50*6mm Amount wt% A(0%) B(0.5%) C(1.0%) D(1.5%) E(3.0) 1- GO none 3.77g 7.54g 11.31g 22.62g 2- rGO Control Group

Step 3 : Mechanical Evaluation Bending Strength Fracture Toughness

Bending Strength (MPa) Fracture Toughness (MPa·M1/2) Bending Strength Control Group Fracture Toughness Additive Amount of GO (wt%) Bending Strength & Fracture Toughness influenced by different GO additive amount

Bending Strength (MPa) Fracture Toughness (MPa·M1/2) Bending Strength Control Group Fracture Toughness Additive Amount of rGO (wt%) Bending Strength & Fracture Toughness influenced by different rGO additive amount

Conclusion: rGO has better influence on both Bending strength and Fracture toughness compared to GO Bending Strength (MPa) Bending Strength (MPa) Fracture Toughness (MPa·M1/2) Fracture Toughness (MPa·M1/2) Bending Strength Bending Strength Fracture Toughness Fracture Toughness Additive Amount of GO (wt%) Additive Amount of rGO (wt%)
