Space Without the Weight Grid-Stiffened and Lattice Composite Structures ATG Europe has recently developed a patented manufacturing process that enables significant mass and cost savings for space and launch vehicle applications. Utilizing uni-directional prepregs from Toray Advanced Composites, the grid- stiffened and lattice composite structure is comprised of continuous carbon fiber tows arranged in an overlapping lattice fashion. The application of this architecture can positively impact multiple applications e.g., spacecraft central cylinders—the core component of a satellite’s structure. The structure was manufactured using the Toray Advanced Composites RS-36 epoxy prepreg system, with Toray M55J high modulus fiber as a uni-directional reinforcement. Established as a mat
