Due to the low thermal conductivity of traditional resin-based composite materials

the thermal resistance of composite casing is large

the heat dissipation is slow

and there are bottleneck problems such as difficult heat transfer

too high local temperature

material softening and structural failure

which seriously restrict the further application of composites in helicopter transmission casing. In view of this

this paper carried out the optimization research on the thermal performance of metal-reinforced resin-based thermoplastic composite casing

which shows that compared with the traditional aluminum alloy casing

the metal-filled composite casing maintains good heat dissipation and reduces the weight by about 15%; compared with the pure resin casing

the maximum temperature performance is reduced by 69.4%

effectively improving the heat dissipation performance.
