The elongation at break, tensile strength and tearing strength of the HVSSBR cured with EV system are the best.
研究结果表明，浆膜断裂伸长率和断裂比功大的。拉伸模量小的浆料上浆的浆纱耐磨性较好，织造性能也较比良。
Results show that yarns sized by sizes with films of higher breaking elongation and specific work of rupture and lower initial modulus have better abrasive resistance and weaving performance.
选择适当的温度和拉伸比进行热定形，可提高PTT织物的断裂强力和弹性回复率，但其延伸性变差。
The breaking strength and resilient-elasticity recovery of PTT fabric can be increased under suitable temperature and drawing ratio during heat setting, but its dilatability took worse.
本发明的产品的拉伸强度和断裂伸长率高、成本低廉、具有可生物降解性。
The production of this invention has high tensile strength and extension at break, costs little, and is biodegradable.
经C路径的二次ECAE加工后试样为各向同性材料，其缺口冲击强度较PP有所提高，拉伸强度下降，断裂伸长率提高，表现出很好的延伸性。
The specimen by route C ECAE processing was isotropic and its impact strength increased, tensile strength decreased, elongation at break improved and show…
