Keywords： sandwich composite

The sandwich composite based on ramie fiber facesheet and Nomex honeycomb core was produced.The thermal properties of resin and fiber were measured by the differential scanning calorimetry (DSC),Thermogravimetrie analysis (TGA) and melt viscosity spectrometer.Influence of vacuum bag process and autoclave process on large curvature deformation capability and flatwise tension strengths of sandwich composites were studied.The results showed that honeycomb core of 48kg/m3 had very good deformation capability and the flatwise tension strength of sandwich composite by autoclave process is 1.07MPa vs 0.76MPa by vacuum bag process.
