Performances of liquefied bamboo resin foaming material and overlaid foaming materials were tested.The results showed that foam material had a 0.128 g/cm3 average density,an average 0.22 MPa compression strength,an average 0.032 W/（m·K） thermal conductivity,and a 41.7 oxygen index.Composites made with the foam materials had an excellent 37 dB sound insulation value and a 38.1 oxygen index flame retardant performance.
