摘要:
 天然纤维资源丰富、绿色环保、生物可降解等优点吸引了人们的关注，点阵结构的设计可以同时实现材料设计、结构设计与功能性设计。将材料设计与结构设计相结合，以菠萝叶纤维和玻璃纤维作为增强材料，以酚醛树脂和改性的环氧树脂为基体材料，设计了3种不同夹芯组坯方式的点阵圆筒结构，菠萝叶纤维层用P代替，玻璃纤维层用G代替，则3种结构为(PG)n、PGP和GPG结构，并探索了3种圆筒结构的制备工艺；通过轴向压缩试验，分析了3种结构的平压性能。结果表明，纤维缠绕工艺简单可操作；(PG)n、PGP和GPG夹芯点阵圆筒的破坏部位发生在肋条交叉附近的环向与螺旋向肋条；从结构的抗压角度出发，相比于结构PGP和GPG，结构(PG)n不具备优势条件；从轻质高强角度出发，PGP夹芯点阵圆筒的性能最好，GPG结构次之，(PG)n最差；夹芯点阵圆筒可以作为建筑材料使用。
Abstract:
 Natural fibers have many advantages,such as abundant,green,biodegradable,which has been attracted the attention of people.The design of lattice structure contains material design,structural design and functional design simultaneously.Taking pineapple leaf fibers and glass fibers as reinforced materials,phenol formaldehyde resin and modified epoxy resin as matrix materials,this paper combined material design and structural design together,three different combination forms of lattice cylinders with sandwich ribs were designed,namely structure (PG)n,PGP and GPG,where P and G represented pineapple leaf fiber and glass fiber,respectively.The preparation process of three types of lattice cylinder was explored,and the compression performances of three types of structures were analyzed through axial compression tests.The experiment results showed that filament winding method was easy to operate.The failure parts of (PG)n,PGP and GPG lattice cylinders with sandwich ribs were in circumferential and helical ribs,adjacent to the crossover.In compression resistance perspective,compared with structure PGP and GPG,the superiority of structure (PG)n was smaller.In lightweight and high strength perspective,the property of PGP lattice cylinder was the best,the GPG lattice cylinders took second place,and (PG)n was the worst.Lattice cylinders with sandwich ribs could be used as building materials.
