Abstract
A novel pre-form for a fiber reinforced synthetic material vehicle wheel comprises: PA0 a substantially planar spider portion comprising sheet molding compound comprising randomly oriented fiber reinforced resin, substantially all of which fiber is from about 0.5 to 2 inches in length; PA0 a first tubular section comprising fiber reinforced resin sheet surrounding said spider portion about an axis substantially normal to the plane of said spider portion; and PA0 a second tubular section surrounding and substantially coaxial with said first tubular section comprising fiber reinforced resin sheet, said fiber reinforced resin sheet of said first and second tubular sections preferably comprising random, chopped fiber of about 0.5 to 2 inches length and continuous fiber in a ratio of about from 1:1 to 1:4, respectively. A novel fiber reinforced synthetic material wheel is made by compression molding said pre-form.
