Composite transmission housing

A method for manufacturing a composite transmission housing for a vehicle drive train transmission, wherein the transmission housing is configured for sealingly enclosing a set of transmission shafts and gearwheels and a lubricant fluid within an internal space of the housing, the method comprising:

• manufacturing a first carbon-fibre skeleton part having a first attachment region, a second carbon-fibre skeleton part having a first attachment region, a first sealing cover part made of plastic material and having a first sealing surface, and a second sealing cover part made of plastic material and having a second sealing surface,
• assembling the first and second carbon-fibre skeleton parts and first and second sealing cover parts, such that the first attachment regions of the first and second carbon-fibre skeleton parts become mutually connected and defining a rigid structural framework that defines said internal space, and such that the first and second sealing surfaces of the first and second sealing cover parts are pressed together or against corresponding sealing surfaces associated with the first and second carbon-fibre skeleton parts, for providing a sealing envelope around said internal space.
