Abstract
A spinner for a gas turbine engine is disclosed. The spinner may include a body extending between a first and second end comprised of a cured chopped unidirectional fiber pre-impregnated material. The body may have a generally conical shape and may further be plated with a metal or metal alloy.
Claims19
A spinner for a gas turbine engine, comprising:
- a body having a first end and a second end,
- the body being a multi-piece body having a fairing at the first end, a cap at the second end, wherein the fairing and the cap are fastened intermediate the first end and the second end,
- the body having a conical shape wherein each of the fairing and the cap;
- is formed from a nonwoven mat of short segments of chopped unidirectional fiber pre-impregnated material randomly oriented with respect to each other such that the mat is transversely isotropic, and
- has a plurality of surfaces including an inner surface and an outer surface,
- the plurality of surfaces being plated with a metal or a metal alloy plating layer.

A method for manufacturing a spinner for a gas turbine engine from chopped unidirectional fiber pre-impregnated material;
- the spinner comprising:
- a body having a first end and a second end,
- the body being a multi-piece body having a fairing at the first end, a cap at the second end, wherein the fairing and the cap are fastened intermediate the first end and the second end,
- the body having a conical shape wherein each of the fairing and the cap;
- is formed from a nonwoven mat of short segments of chopped unidirectional fiber pre-impregnated material randomly oriented with respect to each other such that the mat is transversely isotropic, and
- has a plurality of surfaces including an inner surface and an outer surface,
- the plurality of surfaces being plated with a metal or a metal alloy plating layer, the method comprising the steps:
- inserting the nonwoven mat of short segments of chopped unidirectional fiber pre-impregnated material into a first mold cavity having a generally conical shape;
- closing the first mold with a second preheated mold cavity having generally conical shape;
- and
- applying pressure to force the nonwoven mat of short segments of chopped unidirectional fiber pre-impregnated material into contact with a mold cavity area.
