Title: Recent Advances in FRP Products for Repair of Infrastructure

Abstract:Since the late 1980s, FRP products have seen increased use in repair and strengthening of concrete structures. The traditional technique is referred to as wet layup where carbon or glass fabric are saturated with epoxy in the field and applied to the structure. In this paper I present several new products that I have developed in recent years. One is very large pre-cured carbon or glass laminate sheets that can be used to repair columns, piles underwater, pipelines, etc. The other is a honeycomb-FRP combination that allows construction of lightweight stiff elements. This product can be used to build pipes that can serve as free-standing elements or in slip-lining repair of deteriorated culverts and pipes. These products can also be used as stay-in-place forms for repair of seawalls, large piers and the like. Examples of field applications are also presented.
