The Characteristics of Infrared Spectra of Kenaf Fiber and its Composite Material

Abstract:

Kenaf fiber modification, its composite material and its basic PE structure were studied by infrared spectrum and SEM in this paper, the research results show as following: 1730 cm-1 peak in Kenaf fiber clearly becomes weak and 1647 cm-1 peak reduces even disappears via KH-550 coupling treatment. The reaction intensity increases between C-O bonds in 1070 ㎝-1 and C-O-C bonds in 1160㎝-1 with coupling reaction. After KH-550 silane coupling treatment, Kenaf fiber’s C=O bond at 1750 ㎝-1 and PE composite material’s -OH bond at 1250㎝-1 weakens obviously, result in a better compatibility, which is consistent with mechanical property and SEM microstructure of composite materials.
