 Have a look at the "translate" option of the Raster menu.
 Or, perhaps quicker, use GDAL commands from a "command" prompt:
 -> gdal_translate your_input_3-band_raster_filename 
 Output_filename_band1.tif -b1
 -> gdal_translate your_input_3-band_raster_filename 
 Output_filename_band2.tif -b2
 -> gdal_translate your_input_3-band_raster_filename 
 Output_filename_band3.tif -b3
