Manufacturing method of sandwich honeycomb structure based on carbon fiber reinforced carbon composite material

摘要

The present invention relates to a method for manufacturing a sandwich honeycomb structure.;It is an object of the present invention to provide a lightweight honeycomb type carbon fiber reinforced composite material that can be used even at an ultra-high temperature.;The manufacturing method of the present invention is characterized in that the core portion of the honeycomb structural member and the outer surface portion of the sheet are made of a carbon fiber-reinforced composite material.;The sandwich honeycomb structural member according to the present invention is very light, but has excellent non-strength and shape stability and excellent energy absorption ability, and therefore can be used as an inner wall material for an aircraft and the like.
