Henequen fiber was air-stabilized, carbonized, and steam-activated to obtain high surface area activated henequen fiber (AHF). Thermal behavior of henequen fibers has been studied by TGA. The structural morphology and characteristics were observed by SEM and BET surface area measurement. The yield of AHF from natural henequen was in the range of 20~25 wt%. Mesopores (2~2.5 nm) were developed on the AHF as the activation temperature was raised up to 700 o C, and the band of mesopore size distribution moved to 15~30 nm when the activation were carried out at 900 o C for 30 min. The specific surface area and the total pore volume were about 1394 m 2 /g and 1.30 cm 3 /g, respectively at this activation conditions.

“…This was because of the reaction that occurred between some of the hydroxyl groups of cellulose on the surface of the fiber and the hydroxyl groups of silanol (obtained after hydrolysis of silane). Thus, an ether bridge, -Si-O-Si-, and -Si-O-C-bonds were introduced on the surface of the fibers (Valadez-Gonzalez et al 1999;Cui et al 2008), which led to the appearance or the increase in the absorbance in the regions of 1230 and 1030 cm -1 . The peak at approximately 1730 cm -1 was due to the esterification of the hydroxyl groups, which resulted in an increased stretching vibration of the carbonyl (C=O) group present in the ester bonds (Silverstein et al 2014).…”

Wood fibers were modified with alkaline solution and silane coupling agent to study changes on the fiber surface and the influence of these treatments on the mechanical properties, flame resistance, thermal conductivity, and microstructure of wood fiber-phenolic foam composites. Test results indicated that the lignin, waxes, hemicelluloses, and other impurities from the fiber surface were partially dissolved and removed. The mechanical properties of treated wood fiber-phenolic foam composites increased dramatically, the cellular pore distribution was more regular, the size of bubble cells was smaller and more uniform, and the thermal conductivity was reduced, and, in particular, the fragility of treated wood fiber-phenolic foam composites decreased. However, with increasing wood fiber content, the mechanical properties and limited oxygen index (LOI) of composite foam decreased. By comprehensive analysis, it was shown that the interfacial compatibility between the fibers and phenolic resin was improved. Nevertheless, the amount of wood used could not be too high, and the optimum amount was approximately 5%.
