1. A method of manufacturing a monolithic composite tank body for a waste or water system on board an aerospace vehicle, the method comprising:
providing a mold comprising a desired interior shape of the monolithic composite tank body wherein the mold comprises at least three co-linear formations that form at least three co-linear openings on a first side of a monolithic composite tank body, and wherein the openings are configured to be in fluid communication with at least one sink, toilet, faucet, piping, or tubing, wherein the first side is a longest side of a plurality of sides of the monolithic tank body;
applying a first curable composite material to the mold, wherein the first curable composite material comprises a first resin;
applying a second curable composite material to the mold comprising the first curable composite material, wherein the second curable composite material comprises a second resin that is different from the first resin;
co-curing the first curable composite material with the second curable composite material to form the monolithic composite tank body;
removing the mold; and
performing a second curing process on the monolithic tank body after the monolithic tank body is removed from the mold.
