Composite Gear Housing
Fiber reinforced composite material is used for weight reduction of engineering structures. Carbon fiber reinforced composite plastic material is commonly used in the aerospace industry. John Barnard tried to incorporate this material in a gear housing for the Ferrari F1 car in 1994, but instead only mounted the metal gear case on a carbon fiber composite support. Since then several F1 teams including both Honda (née B.A.R) and McLaren have raced 'Carbon' cases with substantial composite content.
In 1969 General Motors investigated using composite transmission cases to reduce manufacturing cost.
In 2004 the US Department of Defense decided to finance development of a composite gear housing for a main rotor helicopter planetary gear box. Boeing and Sikorsky currently conduct the development of helicopter composite gear housing.

Famous quotes containing the words composite, gear and/or housing:
“A positive learning climate in a school for young children is a composite of many things. It is an attitude that respects children. It is a place where children receive guidance and encouragement from the responsible adults around them. It is an environment where children can experiment and try out new ideas without fear of failure. It is an atmosphere that builds children’s self-confidence so they dare to take risks. It is an environment that nurtures a love of learning.”
—Carol B. Hillman (20th century)
“But Lord, remember me and mine
Wi’ mercies temporal and divine!
That I for grace and gear may shine,
Excelled by nane!
And a’ the glory shall be thine!
Amen! Amen!”
—Robert Burns (1759–1796)
“We have been weakened in our resistance to the professional anti-Communists because we know in our hearts that our so-called democracy has excluded millions of citizens from a normal life and the normal American privileges of health, housing and education.”
—Agnes E. Meyer (1887–1970)
