The present invention relates to the technical field of automobile fuel tanks, and specifically to a wear-resistant
fuel tank for a vehicle, comprising a multi-layer
composite material structure, consisting of an inner tank layer, an outer box layer, and a microchannel network arranged therebetween, wherein the outer box layer is made of high-density
polyethylene or a reinforced
composite material, and the microchannel network is pre-filled with a repair agent, and when the
fuel tank is damaged, the repair agent flows to the damaged area through
capillary action, thereby achieving automatic repair and preventing oil leakage. Buffer end boxes and heat exchange guide boxes are provided at both ends of the
fuel tank of the present invention, which are connected through elastic floating connections to absorb the
impact force generated by the oil during the driving of the vehicle, thereby avoiding damage to the fuel tank and extending the service life of the fuel tank. The present invention provides a highly durable, safe and efficient fuel tank, which has multiple functions such as buffering, repairing, heating and intelligent monitoring, and is suitable for vehicle fuel tank needs in various complex environments.
