APPENDIX F
INTERIOR BUILDING MATERIALS AND
COMPONENTS Building materials and components must be developed for
use inside the colony compatible with the selected modular framing
system. The need is for light and strong floor deck elements, light
and fireproof interior wall elements, light, fireproof, and
acoustically treated exterior wall elements, and fireproof ceiling
assemblies. All of these elements must be selected on the basis of
their specific functional use, concern for safety against fire,
smoke and human panic, and appropriateness to their relationship
within the overall design context of the interior environment of
the colony. The elements have been designed assuming the
availability of sufficient amounts of aluminum that meets the
necessary strength requirements of NASA report MSC-01-542 (2) .Also assumed
available is a silicon-based fiberboard similar to terrestrial
mineral fiber insulation board. The systems chosen are shown in
table 4-8.

TABLE 4-8.- WALL CONSTRUCTIONS
| Exterior wall system
Cellular silicone glass (10 cm) with
22 ga. aluminum skin on each side, 191 Pa
(4 lb/ft^2)
or
2.5 cm aluminum honeycomb with 5 cm
silicone foam glass and 22 ga. aluminum skin
on one side, 164 Pa (3.5 lb/ft^2)
|
| Interior wall system
5 cm aluminum honeycomb with 22 ga.
aluminum skin on both sides, 120 Pa (2.5 lb/ft^2)
|
For floor and roof systems the lightest constructions generally
available on Earth are composed of light, openweb framing,
suspended ceilings, and metal floor decking. This is chosen for the
baseline. Stressed skin panel construction made from aluminum web
members and aluminum skin is also light and therefore a viable
alternative. For a 9 m span and residential live loads (unreduced)
of 1.9-2.9 kPa (40-60 1b/ft^2), the dead loads for each of these
systems are given in figure 4-21 and figure 4-22.
