“…[ 19 ] However, they are usually for one‐time usage, after which the constituents are permanently damaged. This shortcoming can be partially overcome by incorporating damage‐tolerant micro‐lattices [ 20 , 21 , 22 , 23 , 24 , 25 ] or phase‐transforming constituents [ 26 , 27 , 28 ] that allow the materials to undergo cyclic loadings, although the performance decreases along cycles.…”

Energy-absorbing materials with both high absorption capacity and high reusability are ideal candidates for impact protection. Despite great demands, the current designs either exhibit limited energy-absorption capacities or perform well only for one-time usage. Here a new kind of energy-absorbing architected materials is created with both high absorption capacity and superior reusability, reaching 10 kJ kg −1 per cycle for more than 200 cycles, that is, unprecedentedly 2000 kJ kg −1 per lifetime. The extraordinary performance is achieved by exploiting the rate-dependent frictional dissipation between prestressed stiff cores and a porous soft elastomer, which is reinforced by an intertwined stiff porous frame. The vast interfaces between the cores and elastomer enable high energy dissipation, while the magnitude of the friction force can adapt passively with the loading rate. The intertwined structure prevents stress concentration and ensures no damage and reusability of the constituents after hundreds of loading cycles. The behaviors of the architected materials, such as self-recoverability, force magnitude, and working stroke, are further tailored by tuning their structure and geometry. This design strategy opens an avenue for developing high-performance reusable energy-absorbing materials that enable novel designs of machines or structures.

Honeycomb structures are frequently used in many constructions today. For this reason, the investigation of the mechanical properties of products produced from honeycomb structures is a current issue. In this study, the bending strengths of sandwich structures with honeycomb core produced with a three-dimensional printer using ABS and PLA materials were experimentally investigated. In the experiments, the effect of the cell diameter change of the honeycomb core on the bending strength was investigated experimentally in the sandwich structures. For this purpose, experiments were carried out for three different cell diameters. A total of eighteen three-point bending tests were applied, with each experiment repeated three times. In addition, positioning equipment has been specially designed and produced to increase the reliability of the experiments. As a result of the experiments carried out, force-elongation curves were obtained. It has been determined that the samples produced from PLA material are more durable than ABS samples. In addition, it was determined that the samples with a cell diameter of 9 mm had the highest strength, while the samples with a cell diameter of 12 mm had the lowest strength for both materials.

The optimized design of 3D‐printed continuous fiber reinforced composites (CFRCs) at the structural level provides the possibility of further performance improvement. Herein, a design scheme of three‐point bending heterogeneous 3D‐printed continuous carbon fiber reinforced composites (CCFRCs) based on fiber volume fraction is reported. It is found experimentally that, compared with the pure polylactic acid (PLA), the force bearing capacity of the three designed CCFRCs with different fiber volume fractions increases by 190.46%, 222.36%, and 253% with the raise of fiber content, and flexural modulus increases by 369.32%, 426.05%, and 549.41%, respectively. Another discovery is that the spatial arrangement of fibers is also an important factor affecting the bending performance, and it is concluded that the bottom region's fiber content has a significant effect on the bending performance, with the same fiber content (10.20%), the load withstood with a larger fiber volume fraction setting of the bottom layer is 117.69% of that with a smaller one. The failure modes are observed using cone beam computed tomography and the main failure causes of the structures are analyzed. Herein, a solution for the lightweight structure design is provided as well as improves its comprehensive performance, further promoting the potential application of 3D‐printed CCFRCs.
