The research determined the resistance to compression and low velocity impact of wood-based sandwich panels, the face sheet made of high-density fiber board, and high pressure laminate, while its auxetic lattice core was made by 3D printing using LayWood bio-composite filament. The core's auxetic property (i.e. exhibiting negative Poisson's ratio) was observed within the planes parallel to the facings. The ability of particular types of multilayer panels to absorb the energy was also determined. Based on the analysis of the obtained test results, it was proven that the core denoted as B, with inclination angle of the cell ribs \({{\varphi }_{x}=\varphi }_{y}=65^\circ\), shows the highest compressive strength. It was determined that the dynamic load causes a very high overload in high-density fiber board face sheets. This results in damage to the sandwich panel surface and core structure. Cells of type B favorably minimize the differences in absorbed energy when using different face sheets and the energy value for low velocity impact. Taking into account the amount of absorbed energy, the most attractive is the panel with the D-type orthotropic core characterized by an inclination angle of the cell ribs \({\varphi }_{x}= 30^\circ , {\varphi }_{y}=60^\circ\). The amount of energy absorbed by samples with high-density fiberboard face sheets increases significantly depending on the impactor's energy. For panels with face sheets manufactured from high-pressure laminate, the amount of energy absorbed decreases.

该研究确定了人造板，高密度纤维板制成的面板和高压层压板的抗压性和低速冲击性能，而其膨胀型格芯是使用LayWood生物复合材料丝线通过3D打印制成的。在与饰面平行的平面内观察到了芯的膨胀特性（即呈现负泊松比）。还确定了特定类型的多层面板吸收能量的能力。在对获得的测试结果进行分析的基础上，证明了核心为B，其单元肋的倾斜角为\（{{\ varphi __x} = \ varphi} _ {y} = 65 ^ \圆\），显示最高的抗压强度。已经确定，动态负载在高密度纤维板面板中引起很高的过载。这会损坏夹心板的表面和内芯结构。当使用不同的面板时，B型电池有利于最小化吸收能量的差异以及低速冲击的能量值。考虑到吸收能量的量，最吸引人的是具有D型正交异性芯的面板，其特征在于单元肋的倾斜角 \（{\ varphi} _ {x} = 30 ^ \ circ，{\ varphi } _ {y} = 60 ^ \ circ \）。具有高密度纤维板面板的样品吸收的能量数量会根据冲击器的能量而显着增加。对于具有由高压层压板制造的面板的面板，吸收的能量减少。
