Kevlar0 3 is a material formed by combining para-phenylenediamine and terephthaloyl chloride. Aromatic polyamide (aramid) threads are the result. They are further refined, by dissolving the threads and spinning them into regular fibres. When woven, Kevlar0 3 forms a strong and flexible material. If layers of the woven Kevlar0 3 are combined with layers of resin, the resulting ¡®rigid¡¯ material is light and has twenty times the strength of steel. It is also superior to specialist metal alloys. However, Kevlar0 3 is expensive due to the demands of the manufacturing process and the need for specialist equipment.
Nzuri na zilizo imara. nizile zilizo andikwa chagua KIKWETE. wanazovaa wanakijiji masikini
Habari wana inteljensia.
Naomba kufahamu sababu ya
1. Kwa nini bullet proof inavaliwa kifuani tu na kuacha kichwa kikiwa vurnerable na risasi?
2. Kwa nini mtu anae shoot mara nyingi analenga kifuani na sio kichwani hata kama wapo karibu na mshutiwa?
3. Hizi bullet proof zinatofautiana kwa ubora au zote zina fanana?
Mfano anayotumia Kikwete na anayotumia Obama.
4. Mwisho, material yanayotumika kutengeneza bullet proof ni yepi?
Asanteni.
