不同铺层方式下连续玻璃纤维/聚丙烯复合材料波纹夹芯板的力学性能
|
Abstract:
制备了多种铺层方式的连续玻璃纤维/聚丙烯（GF/PP）复合材料波纹夹芯板，并研究了GF/PP复合材料波纹夹芯板的平压性能和弯曲性能。结果显示：面板相同时，增加芯板厚度可大大增加夹芯板整体的平压性能；芯板相同时，面板的铺层方式对夹芯板的平压性能有一定影响，且面板含有0°和90°铺层的波纹夹芯板具有最高的平压模量，为59.55 MPa，而单纯增加面板厚度对提升波纹夹芯板的平压性能影响不大；面板铺层方式对弯曲性能具有较大影响，面板为0°铺层的波纹夹芯板具有最高的横向弯曲模量，为783.66 MPa，面板为90°铺层的波纹夹芯板具有最高的纵向弯曲模量，为732.09 MPa；面板为单向铺层（0°或90°铺层）时，会使夹芯板另一方向（纵向或横向）的弯曲性能形成短板。 Continuous glass fiber/polypropylene (GF/PP) composite corrugated sandwich panels with different laminates were prepared in this paper. The effects of different panels and core materials on the mechanical properties of corrugated sandwich panels were studied, including flat compression and bending properties. The results show that under the same panel, increase the thickness of the core board can greatly increase the overall flat-pressure performance of the sandwich panel. Under the same board, the method of laminating the panel has certain influence on the flat pressure performance of the sandwich panel. The corrugated sandwich panel with 0° and 90° layers has the highest flatwise compression modulus of 59.55 MPa, while the overall flatwise compression properties of those panels with the same layers cannot be increased significantly by only increasing panel thickness. The panel lay-up method has a great influence on the bending performance. The corrugated sandwich plates with 0° outer layer have the highest transverse bending modulus of 783.66 MPa, while the corrugated sandwich plate with 90° outer layer have the highest longitudinal flexural modulus of 732.09 MPa. However, for the panels with the single layers(0° or 90° layers), the bending property along a certain direction of sandwich panel will be a short board. 国家自然科学基金委科学技术产业化项目（U1664250）；国家重点研究发展计划（2016YFB0101606）；国防基础科研计划（A0520131001）；中国航天科技集团第一研究院项目（2017AV33675
