    摘要: A method of producing a divided conduit containing, in order forming a strip-shaped textile having a first longitudinal edge and a second longitudinal edge, extruding a molten thermoplastic polymer into the form of an at least partially molten conduit having an inner surface and an outer surface, and placing at least one strip-shaped substrate within the at least partially molten conduit during or directly after conduit formation such that the first longitudinal and second longitudinal edges of the strip-shaped substrate embed into the inner surface of the conduit. The strip-shaped textile is selected from the group consisting of a woven, non-woven, and knit and the strip-shaped textile is air permeable. The inner surface and outer surface of the conduit is continuous.

    摘要: A fiber reinforced polymer strengthening system having a concrete structural member having at least one outer facing surface. At least one pultruded element is located on the outer facing surface of the concrete structural member, the pultruded element containing a matrix material having a Tg of at least about 110° C. and a plurality of fibers having a tensile strength of at least about 300 MPa and an operating temperature of at least the Tg of the matrix material. Also located on the outer surface of the concrete member and at least partially covering the at least one pultruded element is an inorganic binder comprising an inorganic material having an operating temperature of at least about Tg of the matrix material of the pultruded element.
