Pultrusion processes for producing fiber reinforced polyurethane compositions and polyurethane-forming reaction mixtures suitable for use in such processes |
| abstract |
Pultrusion processes for producing fiber reinforced polyurethane composites. The process includes: (a) continuously pulling a roving or tow of continuous fiber reinforcing material successively through an impregnation chamber and a die; (b) continuously feeding a polyurethane-forming reaction mixture to the impregnation chamber; (c) contacting the fiber reinforcing material with the polyurethane-forming reaction mixture in the impregnation chamber such that at least partial wetting of the material by the formulation occurs; (d) directing the fiber reinforcing material through a die heated to reaction temperature to form a solid composite; and (e) drawing the composite from the die. The polyurethane-forming reaction mixture comprises (i) a polyisocyanate, (ii) a polyol; and (iii) a catalyst composition comprising a chelated organometallic/metalorganic catalyst. Polyurethane-forming reaction mixtures suitable for use in such processes are also described. |
