【摘要】 选用玄武岩纤维为增强材料,制备了NOL环试样,进行了湿热处理和剪切试验验证。根据网格理论,针对2.4 L玄武岩纤维缠绕气瓶进行了复合层设计,确定了纤维缠绕厚度和缠绕角度,对所制样品进行了疲劳及爆破试验验证。结果表明:玄武岩纤维复合材料较玻璃纤维复合材料具有更优的界面粘结和湿热老化特性,所制备的气瓶经过0-21^+0.2-0 MPa压力循环的10 000次疲劳实验后未发生泄漏;爆破压力为77.1 MPa,验证了设计的合理性。更多还原

【Abstract】 In this paper,basalt fiber was used to produce the NOL rings and 2. 4 L fiber fully wrapped cylinders. The shear strength of the NOL rings before and after hygrothermal treatment was studied. The composite layers of the cylinder were designed based on the gird theory,and the composite layer thickness and winding angle were determined. In order to validate the rationality of the design,the pressure cycle test and burst test were studied. The result shows that the basalt fiber reinforced composites has better interphase adhesive and hygrothermal properties than glass fiber reinforced composite. There is no leap on the cylinder after 10000 times 0-21^{+ 0. 2}-0 MPa pressure cycle test,and the burst pressure is 77. 1 MPa. The results show the design is reasonable and accurate.更多还原
