Method for manufacturing rim composites |
| abstract |
METHOD FOR MANUFACTURING RIM COMPOSITES ABSTRACT OF THE DISCLOSURE A polyurethane RIM method has two mixheads. Reactants are brought to each mixhead and are supplied as separate streams to two spaced cavities in a mold having a pre-formed porous mat separating the two cavities. One stream contains an isocyanate, polyol, chain extender and crosslinker selected to have a very low viscosity and which reacts to produce a high modulus armature or load bearing member. The other stream contains a polyol and isocyanate with additives that have relatively high viscosity to produce a semi-rigid polyurethane foam. At each mixhead the proportions of ingredients are controlled to give a desired isocyanate index to control the flex modulus and other properties of the loading bearing member and foam molded components of the product. The low viscosity material penetrates the porous mat to reinforce it and the porosity of the mat prevents the high viscosity material from entering the armature cavity so as to reduce the load capacity of the finished product. |
