Abstract

The invention relates to a lamp post made of a composite material. The lamp post comprises a post body and a post arm, wherein the lamp body is composed of an outer wall layer and an inner core layer, the outer wall layer is composed of continuous fiber reinforced resin and the inner core layer is composed of resin concrete; the post arm is composed of continuous fiber reinforced resin; the fiber is selected from at least one of glass fiber, carbon fiber or basalt fiber, and 30-95% fibers of the post body is in axial distribution; and the resin is unsaturated polyester resin, vinyl resin or ethoxyline resin, the resin concrete is composed of 15-30% of resins, 0-20% of short glass fibers and 50-80% of 10mu m-4mm inorganic particle paddings. The lamp post made of the composite material provided by the invention has the characteristics of beautiful appearance, never rustiness, long service life, low manufacturing cost, wide popularization value and the like, and can be used for replacing steel resources.

Description

technical field [0001] The invention relates to the field of street lamps, in particular to a composite material street lamp pole. technical background [0002] After decades of development, light poles have evolved from wooden light poles to cement light poles. Carbon steel light poles appeared in the 1970s. In recent years, hot-dip galvanized surface treatment technology has been developed, and the anti-corrosion ability of carbon steel light poles has been further improved. improved, but did not fundamentally solve the problem. Some people use stainless steel to make street light poles. Although it solves the corrosion problem and is beautiful, the production cost is too high and it is difficult to promote. Contents of the invention [0003] The object of the present invention is to provide a composite material street light pole with the characteristics of high strength, never rusting, long service life, low manufacturing cost, and replacing steel resources. [0004] ...
