The glass fibers carrying the dried residue of an aqueous chemical treating composition containing the unique chemical treating composition can be used to prepare a thermosetting plastic composite having improved strength. The composites so prepared are useful in making clear, translucent panels of improved weatherability and pultrusion profiles having higher strengths, such as compressive, shear and flexural strengths. | |
