Interface failure and delamination resistance of fiber-reinforced geopolymer composite by simulation and experimental method

Original language description

Fiber-reinforced geopolymer matrix composites (FRGC) have the potential areas of application to bridge the gap between the performances of polymer matrix and ceramic matrix composites. One of the major drawbacks of the geopolymer matrix is the extreme brittleness and weak interlaminar strength. To improve the interlaminar strength of composites, reinforcement of fibers such as carbon and E-glass are considered as fillers in the matrix. The study aimed to evaluate the inner strength and delamination behavior of carbon and E-glass fiber-reinforced composite. The inner structure of the delaminated area of the impacted composite is examined based on the microstructural images and internal areas. The study is being evaluated by simulation method and experimental observation was correlated. The effect of fiber reinforcement was evaluated using three-point flexural methods to obtain strength and modulus of rupture. Results indicate that the interlaminar strength of carbon fiber reinforced geopolymer composite is stronger than E-glass fiber-reinforced composite. The fibers are more intact in carbon fiber reinforced geopolymer composite with better delamination resistance and less impact area. However interlaminar strength of E-glass fiber reinforced is weak, leads to less delamination resistance, with more slippery behavior and more damage area.
