Abstract
Segmented shields are disclosed comprising material combinations and rolled configurations to impede and mitigate through-and-through penetration damage of a structure incorporating the segmented shields from the damage resulting from the impact of high-velocity micro-meteoroids and orbital debris particulate.
Claims22
An apparatus comprising:
- a housing, said housing comprising a housing inner surface and a housing outer surface;
- the housing inner surface comprising:
- a plurality of shield segments, said plurality of shield segments oriented proximate to the housing inner surface to form a segmented shield, said shield segments comprising:
- a first material component, said first material component comprising a first fiber material, said first fiber material having a tensile strength of at least about 3620 MPa and a relative density of about 1.44, said first material component having a first material component thickness;
- and
- a second material component, said second material component comprising a second fiber material that is different from the first fiber material, said second fiber material comprising a continuous filament ceramic material, said second material component having a second material component thickness, said second fiber material configured to substantially surround the first material component;
- a third material component, said third material component comprising a third fiber material, said third fiber material comprising a silica fiber cloth material, said third fiber material configured to substantially surround the second fiber material;
- wherein the first material component is configured into a first material component rolled configuration comprising the first material component thickness, and said first material component rolled configuration further comprising an inner core, said inner core bounded by the first material component;
- and
- wherein the second material component is configured into a rolled configuration about the first material component thickness.
