| Research Abstract |
In this study, in order to reduce weight of CFRP nozzle liner for solid rocket motors, reinforcements with 3D carbon fiber structure and new foamed resin impregnation method were examined. Several kinds of process condition were examined through the bending test, measurement of thermal conductivities, and erosion test. Finally better fabrication method for light weight nozzle liner could be established.
