Umurongo wimbere ni uwuhe?
Isahani yo hanze n'ibikoresho bya bffer bikozwe muri plastiki, kandi urumuri rw'umusaraba rwashyizweho kashe mu gikingi cya U gifite urupapuro ruzengurutse ubukonje rufite uburebure bwa 1.5mm;Isahani yo hanze hamwe nibikoresho bya buffer bifatanye kumurongo wambukiranya umusaraba, uhujwe nurwego rurerure rumuri rwimigozi kandi rushobora gukurwaho umwanya uwariwo wose.Plastike ikoreshwa muri bamperi ya pulasitike muri rusange ikozwe muri polyester na polypropilene ukoresheje inshinge.Kurugero, bumper yimodoka ya Peugeot 405 ikozwe mubikoresho bya polyester kandi bikozwe muburyo bwo gutera inshinge.Amashanyarazi ya Audi 100 ya Volkswagen, golf, Santana muri Shanghai na Xiali muri Tianjin akozwe mu bikoresho bya polypropilene akoresheje inshinge.Hariho kandi ubwoko bwa plastike bwitwa polyakarubone sisitemu mumahanga, yinjira mubice bivanze kandi igakoresha uburyo bwo kubumba inshinge.Bumper yatunganijwe ntabwo ifite imbaraga zikomeye gusa, ahubwo ifite ibyiza byo gusudira, ariko kandi ifite imikorere myiza yo gutwikira, kandi ikoreshwa cyane mumodoka.
Uburinganire bwa geometrike ntibushobora gusa guhuza imiterere yikinyabiziga cyose kugirango habeho ubwiza, ahubwo bugomba no kubahiriza imiterere yubukanishi hamwe n’ibiranga imbaraga zo kwinjiza ingufu kugirango habeho kwinjiza no kunyeganyega mu gihe cy’ingaruka
