Cone calorimetry shows reductions of 41.6% in peak heat release rate (PHRR), 23.4% in total heat release (THR), and 21.6% in total smoke production (TSP). The mechanical properties demonstrate great improvement, most notably a 165.3% increase in impact strength. The dielectric properties are also ameliorated, with the dielectric constant dropping to 3.85 at 1 MHz.

However, a single core topology that concurrently excels in both mechanical and thermal performance remains a significant challenge. To address this issue, this paper employs a hybrid concept to design a novel plate-added X-lattice core sandwich structure (PX) with concurrent thermal and mechanical load-bearing capabilities. The compressive properties of PX, fabricated by Selective Laser Melting (SLM) technique, are comprehensively investigated by combining experimental, theoretical, and numerical methods at 25∼800 °C.The results indicate that the compressive strength of PX decreases by approximately 41.6 % as the temperature increases from 25 °C to 800 °C. During the compression process, there exists a mutual restraint effect between the struts of the X-lattice and the plate. Due to the limited plasticity of the printed Ni718 alloy, after yielding, the specimens exhibit catastrophic failure, leading to suboptimal energy absorption performance at varied temperatures. Additionally, systematic parameter studies quantitatively demonstrate the influence of specific parameters on the specified strength of the proposed structure.

This paper proposed a novel theoretical model for cutting composites considering matrix elasto-plastic properties. The model first characterized the coupled constraint relationship between fiber and matrix, and quantitatively analyzed the impact of matrix elasto-plastic properties on material removal. Comparative investigations and validations for CF/PEEK and CF/epoxy were conducted under 25 °C and 200 °C. The proposed model has improved predicting accuracy for subsurface damage, cutting force and thrust force by 13.48%, 5.49%, and 17.47%, respectively, comparing to that without considering plasticity. Moreover, the influence mechanism of matrix plasticity on the material removal process was elucidated by the model.
