Structure
AMAP is making use of new advanced steel alloys, Aluminium-Titanium alloys, nanometric steels, ceramics and nano-ceramics. The new high-hardened steel needs 30% less thickness to offer the same protection level as ARMOX500Z High Hard Armour steel. While Titanium requires only 58% as much weight as rolled homogeneous armour (RHA) for reaching the same level of protection, Mat 7720 new, a newly developed Aluminium-Titanium alloy, needs only 38% of the weight. That means that this alloy is more than twice as protective as RHA of the same weight.
AMAP is also making use of new nano-ceramics, which are harder and lighter than current ceramics, while having multi-hit capability. Normal ceramic tiles and a liner backing have a mass-efficiency (EM) value of 3 compared to normal steel armour, while it fulfills STANAG 4569. The new nano-crystalline ceramic materials should increase the hardness compared to current ceramics by 70% and the weight reduction is 30%, therefore the EM value is larger than 4. Furthermore the higher fracture toughness increases the general multi-hit capability. Some AMAP-modules might consist of this new ceramic tiles glued on a backing liner and overlaid by a cover, a concept which is also used by MEXAS. Lightweight SLAT armour is also part of the AMAP family. In excess new nano-ceramic armour overlaying a vehicle's base armour, which is backed up by a spall-liner, can archieve a weight reduction of more than 40% to meet the Level 3 of STANAG 4569. Furthermore AMAP's glue and lining components are working efficiently even at high temperatures (like 80 °C (176 °F)).
AMAP is a modular protection concept, therefore several modules, some of them in different variants according the required protection level, are formed. The efficiency may be increased if more types of AMAP-modules are used.

Famous quotes containing the word structure:
“Women over fifty already form one of the largest groups in the population structure of the western world. As long as they like themselves, they will not be an oppressed minority. In order to like themselves they must reject trivialization by others of who and what they are. A grown woman should not have to masquerade as a girl in order to remain in the land of the living.”
—Germaine Greer (b. 1939)
“... the structure of our public morality crashed to earth. Above its grave a tombstone read, “Be tolerant—even of evil.” Logically the next step would be to say to our commonwealth’s criminals, “I disagree that it’s all right to rob and murder, but naturally I respect your opinion.” Tolerance is only complacence when it makes no distinction between right and wrong.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 2, ch. 2 (1962)
“The philosopher believes that the value of his philosophy lies in its totality, in its structure: posterity discovers it in the stones with which he built and with which other structures are subsequently built that are frequently better—and so, in the fact that that structure can be demolished and yet still possess value as material.”
—Friedrich Nietzsche (1844–1900)
