自熄

• 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
  研究了不同阻燃剂含量frp的阻燃性能和力学性能,结果表明,阻燃剂加入量为15wt %时, frp氧指数达到了28以上,使该材料达到自熄级水平,但其弯曲强度下降较大。
