- Helically wound multi-filar cables and braids now predominate.
- Plastic pipe reinforced by cross helically wound steel wires (PSP) is a new plastic-matrix steel composite pipe developed in China recently.
- Equation for short-time burst pressure of pipes reinforced by cross helically wound wires (PSP) was formulated based on method of force equivalent.
- OFBG-FRP bar was pultruded with the fiber strands and optic fiber bragg grating sensor, helically wound fiber strands was introduced to bars to improve the bond properties between OFBG-FRP bar and concrete.
在纤维增强聚合物Fiber Reinforced Polymer(FRP)筋拉挤工艺中;将光纤布拉格光栅Optic FiberBragg Grating(OFBG)传感器与普通纤维束一起经过拉挤模具;为改进FRP筋与混凝土的粘结性能;在FRP筋表面螺旋缠绕纤维束;制备了智能OFBG-FRP筋.
- The wind whirled the dead leaves about.
- The wind was whispering in the trees.
