So, in this study, novel hybrid laminates of various symmetric hybrid configurations were fabricated with industrially active carbon, basalt, aramid, and glass fibers using compression molding. The bending behavior of the configurations at various (1, 5, 10, and 20 mm/min) strain rates were monitored by both load–displacement curves and load-induced acoustic signals. The density of acoustic waves, classified and disintegrated by the types of stimuli they originated from, were correlated with the internal structure, types of cracks, and loading rates.

The experiments are conducted to verify the accuracy of numerical homogenization in aspects of effective Young’s modulus in graded direction, showing good agreement with a maximum percentage difference of 14.3 %. The results indicate that lowering the gradient index increases the overall stiffness and yield strength in a nonlinear pattern, while reducing the extremeness of anisotropy in the stiffness and phase wave propagation, making bone tissue engineering structure more similar to bone. Interestingly, it demonstrates the possibility of achieving a bone tissue engineering structure stiffness that is comparable to bone, at the same weight, by adjusting the gradient index. Moreover, the development of bone cells within bone tissue engineering structure not only enhances the stiffness of bone- bone tissue engineering structure composite but also reduces the extremeness of anisotropy of the stiffness. The extended Hill’s model demonstrates a good fit with numerical data, particularly for points near the origin, proving to be an effective approach for constructing the multiaxial critical yield surface of the bone tissue engineering structures, at a reduced computational cost.
