The invention provides a vehicle-mounted tank made of a carbon fiber reinforced composite. The vehicle-mounted tank is formed by combining three to six tank cavities. Each tank cavity is made of an inner liner layer. A rubber air-inflation inner container serves as a die of each inner linear layer, and each inner linear layer is made through a four-dimensional enveloping and winding formation process. The tank cavities are connected with one another through bolts and bonding. Each tank cavity is externally coated with a structural layer. Each structural layer is a glass fiber reinforced thermosetting composite layer and made through a four-dimensional enveloping and winding formation technology. Reinforcing ribs are arranged at the connection positions of the tank cavities. The reinforcing ribs are made of a glass fiber reinforced thermosetting composite and perform hoop winding reinforcing. Through holes are formed among the tank cavities. Supports are arranged at the bottoms of the tank cavities.
