2. Fiberglass spray lay-up process - Wikipedia

   en.wikipedia.org/wiki/Fiberglass_spray_lay-up...

   The gelcoat (a smooth, hard polyester resin coating) is applied to the mould surface and is given time to cure before re-applying. Usually two coats of gelcoat are used. The barrier coat is applied to avoid fibre print and a rough surface through the gel coat. The barrier coat is cured in an oven and left to cool to room temperature.

3. Stitch and glue - Wikipedia

   en.wikipedia.org/wiki/Stitch_and_glue

   The one sheet boat (OSB, cf. oriented strand board) is an outgrowth of the stitch and glue technique. The OSB is a boat that can be built using a single sheet of 4 foot by 8 foot plywood (1.22 m × 2.44 m). Some additional wood is often used, for supports, chines, or as a transom, though some can be built entirely with the sheet of plywood ...

4. Boat building - Wikipedia

   en.wikipedia.org/wiki/Boat_building

   The boat building industry provides for the design, manufacturing, repair and modification of human-powered watercrafts, sailboats, motorboats, airboats and submersibles, and caters for various demands from recreational (e.g. launches, dinghies and yachts), commercial (e.g. tour boats, ferry boats and lighters), residential , to professional (e ...

5. Gelcoat - Wikipedia

   en.wikipedia.org/wiki/Gelcoat

   Gelcoat or gel coat is a material used to provide a high-quality finish on the visible surface of a fibre-reinforced composite. The most common gelcoats are thermosetting polymers based on epoxy or unsaturated polyester resin chemistry. Gelcoats are modified resins which are applied to moulds in the liquid state.

6. Fibre-reinforced plastic - Wikipedia

   en.wikipedia.org/wiki/Fibre-reinforced_plastic

   In the case of damaged reinforced concrete members, this would first require the repair of the member by removing loose debris and filling in cavities and cracks with mortar or epoxy resin. Once the member is repaired, strengthening can be achieved through wet, hand lay-up of fibre sheets impregnated with epoxy resin, applied to the cleaned and ...

7. Glasspar - Wikipedia

   en.wikipedia.org/wiki/Glasspar

   Fiberglass seemed the logical construction material, and Otto Bayer of Wizard Boats was enlisted as laminator. The boat was named the Green Dolphin, and four were built in various lengths. This was Tritt's first effort in fiberglass-reinforced plastic (FRP). By 1948 he was building small fiberglass sailing dinghies, and built the first ever ...

8. Fiberglass - Wikipedia

   en.wikipedia.org/wiki/Fiberglass

   Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth .

9. Carvel (boat building) - Wikipedia

   en.wikipedia.org/wiki/Carvel_(boat_building)

   A carvel boat has a smoother surface which gives the impression that it is more hydrodynamically efficient since the exposed edges of the clinker planking appear to disturb the streamline and cause drag. A clinker certainly has a slightly larger wetted area, but a carvel hull is not necessarily more efficient: for given hull strength, the ...
