Aerospace and Military Aircraft:
- The aerospace industry is estimated to consume about 50 % of advanced composites production in the united states
- The primary matrix materials used in aerospace applications are epoxies, and the most common reinforcements are carbon/graphite, aramid (e.g. Kevlar), & high- stiffness glass fibres.
- Compared
with metals, The principal advantages of advanced composites in aerospace
applications are their superior specific strength
and stiffness, resulting
in weight savings of 10 – 60 % over metal design.
Automotive Industry:
- The principal motivation for introducing PMCs is cost savings because the industry is mature and highly competitive.
- Because of greatly improved corrosion resistance PMC
automobiles could last 20 or more years compared to the current average vehicle
lifetime.
Construction:
A potential high-volume market for PMCs lies in
construction applications especially in.. Construction of
- Buildings
- Brides
- Housing
- Lampposts
- Smokestacks
- Highway Culvets
Medical Devices:
The impact of PMCs on orthopaedic devices such as
- Hips
- Knees
- Bone Plates
- Intramedullary nails is expected to be especially significant
Marine (e.g. Catamaran) : Boat hulls, decks, masts,
propeller shafts, wind surfer
Chemical plants: Process pipes, tanks,
pressure vessels, oil field structure
Sporting goods: Tennis rackets, golf
clubs, hockey sticks, fishing rods, baseball bats, bicycles, skis, canoes, bow,
swimming pools
Biomedical: Teeth, filler, bone replacements,
artificial limbs
Electrical: Panels, switch gear, insulators,
moulding compounds, conductive adhesives
Other: Wind turbine blades, musical instruments,
umbrella, pens, lighters
Limitations of PMC:
- Low maximum working temperature
- Sensitivity to radiation and moisture
- Processing temperature is generally higher than those with thermosets
- Required special processing equipment
- Thermoset resins have poor impact resistance
Advantages of PMC:
- Good inplane stiffness and strength
- Low density
- Relatively low cost
- Corrosion resistance
- Low coefficient of thermal expansion
- Relatively mature technology
- Excellent in-service experience
