【摘要】：针对CNG气瓶在自紧工艺中缠绕层会产生一定的树脂开裂这一问题,讨论复合材料本身属性对缠绕层树脂开裂的影响。提出一种多尺度建模方法,利用微观力学的方法探讨缠绕层的含胶量和纤维直径对树脂开裂程度的影响。结果表明树脂开裂程度随着含胶量的增大而减少,在企业生产的含胶量范围内,含胶量为34%时树脂开裂程度最小。在含胶量为34%时,利用多尺度模型研究了纤维直径对树脂开裂程度的影响,结果表明纤维直径对树脂开裂程度几乎没有影响。由于含胶量是由缠绕张力控制的,因此合理控制缠绕张力可以减少树脂开裂程度。实验验证了模型的准确性并为研究提供了参考,该研究可为改进CNG-2气瓶生产提供理论依据。
[Abstract]:In view of the problem that the winding layer of CNG gas cylinder will produce a certain resin cracking in the self-tightening process, the effect of the properties of the composite material on the cracking of the winding layer resin is discussed. A multi-scale modeling method is proposed to study the effects of rubber content and fiber diameter of the winding layer on the cracking degree of the resin by means of micromechanics. The results show that the cracking degree of resin decreases with the increase of rubber content. In the range of rubber content produced by enterprises, the cracking degree of resin is the least when the content of rubber content is 34. The influence of fiber diameter on the cracking degree of resin was studied by using multi-scale model when the content of rubber was 34. The results showed that the diameter of fiber had little effect on the cracking degree of resin. Because the rubber content is controlled by the winding tension, the degree of resin cracking can be reduced by reasonably controlling the winding tension. The experimental results verify the accuracy of the model and provide a reference for the research, which can provide theoretical basis for improving CNG-2 cylinder production.
