Fiberglass reinforced plastic products having increased weatherability, system and method

摘要

Climbing products containing rails decorated using veil products colored, patterned, painted or in combination with marking methods such as company names and logos and resin formulation designed to withstand exposure to UV radiation with minimal change in appearance which create specific appearances for applications, enhance weathering performance, and facilitate processing efficiency. A combination of a filler free resin or resin with filler and coated veil systems to create a synergistic weather resistance surface with self-contained color, pattern, picture, logo or combination of said same for climbing products. A system for producing components at a rate of greater than 5 ft/min. Various methods, system, a ladder rail.

主权项

1. A pultrusion system for producing a ladder rail, the system comprising:
a prewetting die wetting an unimpregnated middle mat layer with prewetting resin comprising filler; a former compressing a seven-layer laminate of successively stacked unwet, unimpregnated top and bottom roving, mat, and veil layers onto the wet middle mat layer so that the prewetting resin fully saturates each of the top of bottom roving layers and the middle mat layer; an impregnator compacting the compressed laminate while wetting only the top and bottom mat and veil layers with top coat resin; and a curing die forming the ladder rail at a rate of greater than 5 ft/min by curing the compacted laminate.
