摘要
以航天用复合材料豆荚杆为研究对象,开发先进拉挤成型工艺;对半豆荚杆先进拉挤设备的主要模块:放卷装置、预成型装置、热压装置和牵引夹持装置进行设计,完成半豆荚杆先进拉挤原理样机的搭建,并进行了半豆荚杆的试制。试验表明,成型压力为1MPa、热压温度为130℃、累计热压时间为30min条件下制备的半豆荚杆满足产品要求,为复合材料豆荚杆低成本制造提供了一种新方法。
Aiming at astronautic composite lenticular tubes in this paper,the advanced pultrusion technique was developed.Main modules of half lenticular tube advanced pultrusion equipment,including unreeling device,preformed device,hot pressing device and traction clamping device were designed.After setting up the prototype of advanced pultrusion,half lenticular tubes were manufactured.It is shown that half lenticular tubes cured at 130℃for 30 min under the pressure of 1MPa could meet the quality requests.It provides a new method for the low-cost manufacture technique of composite lenticular tubes.
