REINFORCING LAMINATE CONTAINING CARRIER AND EXPANDABLE POLYMER

摘要

A laminate for reinforcing a structural member having a plurality of side walls comprises a carrier having at least one inclined support surface. Each support surface has an outer edge disposed toward a respective side wall. A layer of extruded uncured structural foam is on each support surface and terminates inwardly of the outer edge. The foam expands when cured and tumbles down the inclined support surface of the carrier to become bonded to the side wall as well as the carrier. By being spaced from the outer edge of the support surface, the tendency for the foam to wipe against the side wall is minimized as is the tendency for a worker to touch the foam when the worker places the carrier into the structural member.
