Prisma Composite Preforms

Prisma Composite Preforms were first introduced and sold in 1992, they were custom-built stringers and bulkheads used for recreational water craft. Since 1992, several hundred thousand boats, and many other end item products, have been produced using Prisma products. Their products compete as a lower cost alternative to fiberglass grid and wood systems and boat builders have recognized many benefits, including:

  • Manufacturing space no longer needed for grid manufacturing
  • Grid mold and maintenance are eliminated
  • Structural adhesives or putty are eliminated
  • Installation time is faster than grids and is typically around 20-30 minutes
  • Primary resin bonds can be achieved due to this fast installation time

Prisma Technology

Prisma Preforms are lightweight structural components when properly laminated into fiberglass composite structures, they are manufactured from high quality fiberglass knit fabrics and 2 pcf (nominal) flotation grade polyurethane foam. The patented technology behind Prisma products allow for maximum foam contribution by creating a toughened interface between fiberglass and foam. Some of the benefits of Prisma composite preforms:
  • Support vertical compression and buckling loads
  • Support dynamic loads and improves structural integrity
  • Provide superior bonding
