This invention relates to a composite platform for low-floor electric buses, made of fiber-reinforced plastic utilizing a vacuum infusion method. The platform's key feature is a composite frame (1), consisting of transversal (12) and longitudinal (13) beams. Additionally, inserts (17,21) are incorporated into the beams (12,13) for securely attaching vehicle components. Separate front (2) and rear (3) arches are designed to support the vehicle's axles and suspension components. Further, external steel connections adaptable to specific axle types/models are integrated. Notably, the platform features a flat, three-dimensional deck structure. The deck components (4,5,6), adhered to the frame (1), enhance the platform's horizontal rigidity, and include a rectangular cutout for installing a disabled access ramp. The innovative design allows for the replacement of external connections in the front and rear arches, accommodating different types and manufacturers of axles. This platform provides the benefits of being lightweight and corrosion-resistant while maintaining the necessary strength and rigidity required for vehicle use.
