    摘要： The present invention provides concrete having improved plastic shrinkage crack resistance, comprising: concrete; and non-alkaline resistant glass fibers. The present invention also provides a method of reducing plastic shrinkage cracks in concrete, comprising the steps of: combining cement, aggregate, sand, and water to form concrete; adding a desired amount of non-alkaline resistant glass fibers to the concrete; and mixing the concrete and glass fibers to disperse the glass fibers uniformly throughout the concrete, wherein the glass fibers reduce the amount of plastic shrinkage cracks of the concrete as compared to non-fiber reinforced concrete.

    摘要： The present invention provides non-heat cleaned glass fiber fabrics comprising resin compatible coatings that offer higher tensile strengths than corresponding fabrics that have been heat cleaned and silane finished. These fabrics can be used in a wide variety of applications, such as reinforcements for composites such as printed circuit boards. In one nonlimiting embodiment, the invention provides a non-heat cleaned fabric comprising a plurality of fiber strands in a warp direction and a fill direction, each fiber strand comprising a plurality of E-glass fiber, and having a resin compatible coating composition on at least a portion of a surface of at least one fiber strand, wherein the fabric has a tensile strength of at least 267 Newtons when measured in the warp direction or fill direction. Although not required, the fabric also has a tensile strength of at least 1.5 times that of a corresponding fabric that is heat cleaned by heating the corresponding fabric to a temperature of at least 380° C. for at least 60 hours and silane finished when measured in the warp direction or fill direction.
