What is Effect of Kaolin powder on the static and dynamic behavior of heterogeneous laminate constituted of functionally graded material layers about?

This work investigated the mechanical properties of glass/epoxy laminates reinforced by kaolin powder with graded properties by performing tensile, 3-point bending, impact tests, and compression after impact (CAI) tests. Firstly, we evaluated the effects of mixing parameters on particle dispersion and the effect of kaolin powder rate on the epoxy properties. It was found that the optimal parameters for a good distribution are a temperature of 60°C with 10 min of stirring time and the optimum kaolin powder rate is 5 wt %. Secondly, four graded heterogeneous laminates were elaborated with increased powder rate at each 1, 2, 3, and 4 layers named models 1/1, 2/2, 3/3, and 4/4, respectively. The test results showed that the powder gradient distribution considerably influences the behavior of the composite, with a significant improvement in mechanical properties compared to unreinforced glass/epoxy laminates. The model 1/1 on the top side exhibits the most significant increase in flexural modulus and maximum flexural strength, respectively, compared to the unfilled specimen. The impact tests showed that the powder distribution gradient is essential in absorbing the leading force and ene
