Abstract:The effects of beating degree on of bamboo fibers the structure and property of the core material of vacuum insulation panel made of bamboo fibers were studied in order to obtain the better insulation performance of the vacuum insulation panel. The results showed that the average pore diameter porosity and density of the core material of vacuum insulation panel were 21.7 μm， 75.7% and 0.287 g/cm3 respectively when beating degree of the bamboo fibers was 14.9°SR, thermal conductivity of the vacuum insulation panel was 12.6 mW/(m·k)which load better insulation performance. SEM observation and air permeability testing results showed that the core material became more compact with lower air permeability as further fibrillation of the fibers with increasing of beating degree.
