plywood foam composite construction
those familiar with our plywood epoxy stitch and glue composite method will recognize the procedure. the differences in building methods between plywood composite and foam sandwich result from the difference in stiffness between the two materials. plywood is stiff and will require less molds.
foam sandwich how-to
the differences in building methods between plywood composite and foam sandwich result from the difference in stiffness between the two materials. plywood is stiff and will require less molds. in plywood cored composite the frames and bulkheads can often be used as molds. in favor of the foam is the ease of cutting

plywood-foam-plywood composite: why not? page 2
without accurate scantlings to compare against just a hope really. in fact i'll bet pound for pound the composite hull with plywood skins over foam would be heavier than a similar strength stiffness and weight single skin taped seam plywood hull if only because of the materials involved and plywood thicknesses available.
plywood-foam-plywood composite: why not? boat design net
if you could get plywood that thick which you just about can it would be extremely expensive and still not be as strong as e-glass. on the other hand there are quite a few people on this forum who build plywood over foam at thicker sizes using contact adhesive in some cases .
structural insulated sheathing composite panel building
composite structural insulated sheathing c-sis our 1-1/8″ and 2-1/8″ c-sis insulated sheathing offers a quick alternative to conventional plywood or osb sheathing for conventionally framed wood or metal structures. the 1-1/8″ thick sheathing provides a nominal insulating value of r-6 which when added to a traditionally framed 2 x 4
frp panels fiber-tech industries
commonly called fiberglass reinforced plywood fiberglass reinforced plastic frp panels or simply frp. fiberglass composites have successfully been used in the transportation construction marine military and building industries since 1965.
boatbuilding basics: fiberglass composites and wood
a completely composite hull and deck are generally built much like a cold-molded boat see above but instead of wood veneers being attached to the jig to form the shape sheets panels and strips of composite foam are used and glued together. once the shaped of the hull has been achieved multiple layers of fiberglass and epoxy are applied.
comparing cost and weight of flat panels
comparing cost and weight of flat panels. by jeff wright. epoxy/fiberglass/core cell foam composite plywood panel: construction requires that the panels be cut to fit and then sealed along all the end grain with epoxy. the panels need to be fastened in place with screws wire ties or nails.
kerfkore company foamkore
the eps foam does however offer a more affodable cost due to the different manufacturing processes. both core products have similar density properties and contain no added formaldehyde. foamkore provides up to 80% reduced weight when compared to conventional panels of plywood particleboard and mdf.
