Carbon fiber-based chassis components for portable information handling systems

A portable information handling system, comprising:

• a main chassis component comprising carbon fiber composite material and having a first end and a second end;
• and
• a separate bottom component coupled to the second end of the main chassis component;
• where the main chassis component has a first thickness;
• where a portion of a terminal edge of the second end of the main chassis component has a second wall thickness that is less than the first thickness and is coupled to a mating layer segment of the bottom component with the mating layer segment of the bottom component oriented in a direction parallel to a major plane of the main chassis component;
• and where the combined coupled thickness of the mating layer segment of the bottom component and the second thickness of the terminal portion of the main chassis component is substantially equal to and aligned with the first thickness of the main chassis component.

A method of supporting an housing for a portable information handling system, comprising:

• providing a chassis antenna housing having an antenna cavity defined therein between a first end and a second end of the chassis antenna housing, the chassis antenna housing including a first elongated rib formed on the first end of the chassis antenna housing;
• providing a separate main chassis component comprising carbon fiber composite material, the main chassis component including a second elongated rib formed on a first end of the main chassis component;
• and
• adhering the first elongated rib and second elongated rib together in interlocking mated relationship to form a fixed joint that supports the chassis antenna housing from the first end of the main chassis component in extended cantilevered relationship to the main chassis component.
