2. Polyester resin - Wikipedia

   en.wikipedia.org/wiki/Polyester_resin

   Glass fiber-reinforced composites comprise the largest segment into which UPRs are used and can be processed via SMC, BMC, pultrusion, cured-in-place pipe (known as relining in Europe), filament winding, vacuum molding, spray-up molding, resin transfer molding (RTM). Wind turbine blades also use them [9] as well as many more processes.

3. FR-4 - Wikipedia

   en.wikipedia.org/wiki/FR-4

   FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material. FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing).

   So-called "theft-proof" large plastic packaging for smaller items, which cannot be opened by hand, is typically made from polycarbonate. Lockheed Martin F-22 cockpit canopy The cockpit canopy of the Lockheed Martin F-22 Raptor jet fighter is fabricated from high optical quality polycarbonate.

5. High-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/High-density_polyethylene

   HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE. [6]

6. Sheet moulding compound - Wikipedia

   en.wikipedia.org/wiki/Sheet_moulding_compound

   Sheet moulding compound (SMC) or sheet moulding composite is a ready to mould glass-fibre reinforced polyester material primarily used in compression moulding. [1] The sheet is provided in rolls weighing up to 1000 kg. Alternatively the resin and related materials may be mixed on site when a producer wants greater control over the chemistry and ...

7. Fiberglass - Wikipedia

   en.wikipedia.org/wiki/Fiberglass

   Other common names for fiberglass are glass-reinforced plastic (GRP), [1] glass-fiber reinforced plastic (GFRP) [2] or GFK (from German: Glasfaserverstärkter Kunststoff). Because glass fiber itself is sometimes referred to as "fiberglass", the composite is also called fiberglass-reinforced plastic ( FRP ).
