Abstract:The mechanical properties and aging properties of composite materials were studied by experiments. The results show that the tower made of polyurethane fiberglass composite material by using three-dimensional structure and filament winding technology is suitable for use in  communication monopole. The  communication monopole made of composite material was tested for mechanical performance of the entire tower. Materials of composite material, steel and concrete were compared in aspects of bearing capacity, displacement and economy, and the applicable conditions of the tower made of composite material were given. The references were given for the processing technology of the key nodes of the communication monopole made of composite material. The application of the composite material in the  communication monopole was verified by engineering tower inspection, and related matters that should be noted in practical use were given. The research results can be used for the reference of similar projects.

Keywords:polyurethane fiberglass composite material;  communication monopole; key node; aging property; mechanical property
