High impact resistant laminate surface for a bowling lane
First Claim
1. In a decorative plastic laminate sheet of a length and width for securing to a substrate selected from the group consisting of natural wood, consolidated wood fibers, plywood, flakeboard, chipboard, and hardboard to form therewith all or part of a bowling lane having a surface characterized by a falling ball impact resistance of at least 60 inches, a coefficient of fraction of about 0.16 and a Taber abrasion resistance of at least 500 cycles, said plastic laminate sheet comprising a plurality of thermosetting resin impregnated fibrous core sheets, a melamine resin impregnated decorative fibrous print sheet overlying one of said fibrous core sheets in a contiguous manner, and a melamine resin containing protective layer overlying said decorative fibrous print sheet in a contiguous manner, the improvement which comprises:
- said fibrous core sheets being comprised of individual, adjacent, contiguous and alternating glass fiber fabric sheets and crepe paper sheets, said glass being selected from the group consisting of woven glass cloth, glass net and glass scrim, the interlaminer bond strength between said glass and crepe paper sheets being substantially equal to the interlaminer bond strength between resin impregnated paper core sheets.
