This paper describes the mitigation of shaped charge penetration of steel armour by the use of spaced metallic and composite plates. The target consisted of one or more steel plates of 10mm thickness some of which were backed by 25mm E-glass polyester composite panels at various additional spacings from the rearmost steel plate. A 32mm diameter shaped charge warhead was detonated at a standoff ...

A multi-panel PMC infilled system, using polymer matrix composite (PMC) material, was introduced as new conceptual design for seismic retrofitting. A proposed multi panel PMC infilled system was composed of two basic structural components: inner PMC sandwich infills and outer FRP damping panels. The PMC material had high stiffness-to-weight and strength-to-weight ratios. Therefore, the addition...

TIlls paper describes the design and manufacture of a multifunctional space structure. The analytical techniques used in this project included thermal analyses of structures in various earth orbits, determination of structural requirements from optical performance calculations, designing of near zero Coefficient of Thermal Expansion (CTE) laminates, consideration of manufacturing and material v...
