由于纤维具有良好的质量相关特性,所以与普通结构相比,轻结构纤维增强材料能大大减轻质量。这一优点在捧型结构中更突出。因为在这种结构中,可以根据载荷设计纤维方向,因而纤维能得以充分利用,特别是单向负载的拉杆、压杆及扭杆,纤维方向铺设成0°或±45°可获得所需要的纤维增强复合材料。 A型夹层杆就是一种纤维增强结构(图1)。从图中可以看到,在轻泡沫芯外,沿杆的 Because fibers have good quality-related properties, lightweight structural fiber reinforcements can greatly reduce quality compared to conventional structures. This advantage is more prominent in the holding structure. Because in this structure, the fiber direction can be designed according to the load, the fiber can be fully utilized, especially the uniaxial load rod, compression rod and torsion bar, the fiber direction is laid at 0 ° or ± 45 ° to obtain the required Fiber reinforced composites. Type A sandwich bar is a fiber-reinforced structure (Figure 1). As can be seen from the figure, outside the light foam core, along the rod
