| 中文摘要: |
| 研究芳纶短纤维防刺层自行车轮胎的结构设计、制备方法以及胎体强度和粘合性能的影响因素。结果表明：芳纶浆粕更适用于防刺层；随着芳纶浆粕用量的增大，胎体强度明显提高，但粘合性能下降；随着防刺层厚度的增大，胎体强度增大；在正常硫化区间内，胎体强度和粘合性能波动较小；但随着欠硫或过硫程度的增大，胎体强度和粘合性能的下降幅度较大。 |
| 英文摘要: |
| The structure design and preparation method of the bicycle tire with aramid short fiber anti-stab layer and the influence factor on the strength and adhesion of the carcass was studied.The results showed that aramid pulp was more suitable for the anti-stab layer.With the increase of dosage of aramid pulp，the strength of the carcass was significantly improved，but the adhesion decreased.With the increase of the thickness of the anti-stab layer，the strength of the carcass was improved.During the normal vulcanization time range，the strength and adhesion of carcass fluctuated in a smaller range；but as the degree of under-sulfur and over-sulfur increased，the strength and adhesion of carcass decreased significantly. |
