The aim of this study is to understand the fundamental effects of the woven bamboo arrangement towards increasing ballistic resistance properties. The work focusses on the ballistic limit test known as NIJ V50, which qualifies materials to be registered for use in combat armor panels. The results show that the composites withstood 482.5 m/s ± 5 limit of bullet velocity, satisfying the NIJ test at level II. The findings give a strong sound basis decision to engineers whether or not green composites are qualified to replace synthetic composites in certain engineering applications.展开更多

[Method] 11 F. oxysporum strains of hybrid bamboo were isolated from diseased bamboo tissue in the bamboo base of Guangxi Huajing Bamboo Development Co., Ltd.. Biological characteristics of these pathogens were studied. [ Result] The optimum growth medium and light conditions for 11 strains were different, the optimum growth temperature was 24 -28 ℃, the optimum pH value was 7.0 - 11.0, lactose and D-sorbitol were the best carbon sources, and yeast extract was the best nitrogen source. The optimum temperature for oonidia germination was about 24 -30 ℃3, the best carbon source were maltose, lactose and sucrose, the best nitrogen source was yeast extract and beef extract. The lethal temperature of conidia was 50 ℃ （10 min）. [ Cendusioal The study supplied good theoretical basis for the control of Fusarium wilt disease in hybdd bamboo.展开更多
