What is a PRISMA® Composite Preform?
PRISMA® Preforms are lightweight structural components when properly laminated into fiberglass composite structures. Since their introduction in 1992, the PRISMA® preforms have been used by major boat builders in several hundred thousand recreational boats. The preforms are manufactured from high quality fiberglass knit fabrics and 2 pcf (nominal) flotation grade polyurethane foam by a patented process.

Engineering Considerations
•Vertical compression capability is equal to form compressive strength and bucking load of the foam supported fiberglass side wall
•The PATENTED tie veil interface assures maximum foam contribution by creating a toughened interface between fiberglass and foam
•The interface helps support dynamic loads and helps prevent hull failure
