ATH被广泛添加到聚丙烯(PP)中用于制成阻燃复合材料。PP/ATH复合材料比纯PP材料更具防火性。材料中成分的比例最终取决于应用要求。已有文献对这种复合材料的阻燃性能的提高进行了研究，但对机械强度的影响还没有涉及。本文研究了ATH浓度对PP/ATH复合材料的影响，利用实验测试、ASTM分析公式和有限元方法研究了材料的拉伸、弯曲和断裂特性。研究结果表明：增加ATH对材料的机械强度有不利的影响。
ATH被廣汎添加到聚丙烯(PP)中用于製成阻燃複閤材料。PP/ATH複閤材料比純PP材料更具防火性。材料中成分的比例最終取決于應用要求。已有文獻對這種複閤材料的阻燃性能的提高進行瞭研究，但對機械彊度的影響還沒有涉及。本文研究瞭ATH濃度對PP/ATH複閤材料的影響，利用實驗測試、ASTM分析公式和有限元方法研究瞭材料的拉伸、彎麯和斷裂特性。研究結果錶明：增加ATH對材料的機械彊度有不利的影響。

Aluminium trihydrate (ATH) is being extensively added to polypropylene (PP) to make a fire retardant composite. Blends of PP/ATH composite are more fire resistant as compared to pure PP. Percentage proportion of both the constituents in the final composite depends upon the application. Improvement in the fire retardant properties of such composites have been studied and published in literature but effects on mechanical strength have not been addressed. The effect of concentration of ATH on the strength of PP/ATH composite was presented. The tensile, flexural and fracture properties were studied and discussed. Experimental tests, ASTM analytical formulae and finite element approach were used. It has been found that increase in ATH has an inverse effect on the mechanical strength.
