Performance of Bamboo Fiber Core Board As Sofa Cushion Material

Bamboo fiber is a resourceful and environmentally friendly elastic material, therefore, its application in sofa upholstery material minimizes the environmental problems associated with traditional polyurethane foam. In order to explore the feasibility of bamboo fiber core board as the sofa cushion material, the indentation hardness, support factor, deformation recovery, and constant-load impact fatigue loss of two types of Bamboo Fiber Core Board were analyzed. The mechanical properties of two types of bamboo fiber core boards were compared with polyurethane foam commonly used as padding material for sofa upholstery. The results showed that, compared with the Moso bamboo fiber core boards, the yellow bamboo fiber core boards had better resilience, lower indentation hardness, better support performance, and less performance loss after fatigue. In addition, after fatigue treatment, the thickness loss of yellow bamboo fiber core board was greater than that of PU foam, but the loss of hardness was less, and the loss of elasticity performance was the same as that of medium-soft foam. Moreover, the resilience of the yellow bamboo fiber core board was the same as that of medium-soft sofa foam with a density of 35 kg/m3. Yellow bamboo fiber core board has the possibility of replacing sofa polyurethane foam cushion material in practical applications. This study analyzed the mechanical properties of bamboo fiber core boards and provided a theoretical basis for the application of bamboo fibers in sofa cushion materials.
