摘要: 为研究热处理对棕榈纤维拉伸性能的影响,在不同温度(100~200 ℃,间隔20 ℃)、不同时间(3、6、9 h)条件下对棕榈纤维进行加热处理,并测试其拉伸性能。结果表明:加热温度对棕榈纤维的拉伸性能有极显著影响,随着加热温度的上升,棕榈纤维的杨氏模量逐渐变大,断裂强度和断裂伸长率逐渐降低,并在加热温度为160~180 ℃时纤维的拉伸性能发生突变; 加热时间对棕榈纤维的拉伸性能也有显著影响,即随加热时间的延长,杨氏模量逐渐增大,断裂强度和断裂伸长率逐渐降低。

Abstract: In order to understand the effects of heating treatment on tensile properties of palm fibers, two factorial experiments were performed in the study at various temperature levels(from 100 to 200 ℃ with an increment of 20 ℃)and time(3, 6 and 9 h). The test results showed that the heating temperature exerted extremely significant influence on tensile properties of palm fibers, and higher heating temperature led to higher Young's modulus, lower breaking strength and elongation at break. The tensile properties of palm fibers changed sharply in the range of 160-180 ℃. The Young's modulus of palm fibers increased, and the breaking strength and elongation at break decreased with longer heating time. The influence of heating time was also significant.
