Fiber reinforced raised pavement marker and method of making |
摘要 |
A fiber-reinforced raised pavement marker made of a composite material comprising an isotropic mixture of a polymeric material, reinforcing fibers and a filler material. The results of finite element analysis and composite technology have been combined to produce a pavement marker having high flexural strength and impact resistance without the need for an impact-resistant shell. Durable, high strength composite pavement markers are made by casting a homogenous mixture of chopped glass fibers and a filler material in a polymeric matrix. Placement of a retroreflective lens within the mold followed by pouring and curing the composite material results in a finished product upon release from the mold.
