Fibre reinforced synthetic material wheel.

摘要

The invention relates to a compression mouldable preform of a synthetic material wheel, which pre-form has a substantially planar spider portion (10) comprising random, chopped fibre reinforced resin; a first tubular section (12) comprising fibre reinforced resin sheet surrounding said spider portion (10) about an axis substantially normal to the plane of said spider portion (16); and a second tubular section (13) comprising fibre reinforced resin sheet surrounding and substantially coaxial with said first tubular section, said fibre reinforced resin sheet of said first tubular section and said second tubular section each comprising random chopped fibre and continuous fibre.
