Composites Use in Mass Transit
Led by needs to reduce emissions and increase efficiency, there are a variety of opportunities and efforts toward incorporating lightweight composites into more mass transit vehicles like railcars and buses, from vehicle bodies and frames, to doors, tracks, bogies and battery enclosures.

How are composites used in buses?
Opportunities for composites have arisen as more all-electric buses have been designed and developed.
Like consumer vehicles, battery enclosures for battery-electric buses are likely to use composites for their light weight, design flexibility and tailorability to meet a range of property requirements.
Several all-composite or partially composite all-electric bus designs have also been developed.
