outer flame
解釋
外層火焰-
The flame - retardant and mechanical properties of the frp specimens with different fra ratio were investigated. it is shown that the oxygen index of the resin with the ratio of 15wt % of the fra reachs 28. the specimens are quenchable without any outer forces, however, the bending strength of the specimens decreases significantly
研究了不同阻燃劑含量frp的阻燃性能和力學性能,結果表明,阻燃劑加入量為15wt %時, frp氧指數達到了28以上,使該材料達到自熄級水平,但其彎曲強度下降較大。
