'Li HULL LflYtHS2.2.3 Sector coordinate address in Engineering Hull2.3 HULL LAYERSThe exterior shell of the spacecraft consists of multiplelayers which afford structural and atmospheric integrity for thespaceframe, integral waveguides and field conductive membersfor the structural integrity field (SIF), and pathways forother utilities (including deflector grids), as well as resistanceto radiation and thermal energy.' Exterior00Interior •The exterior shell substrate is composed of interlacedmicrofoam duranium filaments. These filaments are gammaweldedinto a series of contiguous composite segments thatare 4.7 cm thick and are typically two meters in width. Thesubstrate segments are electron bonded to three reinforcinglayers of 1.2 cm biaxially stressed tritanium fabric, whichprovide additional torsion strength.00000In areas immediately adjacent to major structural members,four layers of 2.3 cm fabric are used. The substrate layeris attached to the major structural members by electronbondedduranium fasteners at 2.5 cm intervals. The substratesegments are not intended to be replaceable, except byphase-transition bonding using a transporter assembly jigduring major starbase layovers.000nIT'.
