Second, many mechanical properties are tested, for example, tensile strength and tensile modulus, flexural strength and flextural modulus and impact strength. by the analysis of the tensile stress - strain curves and the flexural stress - strain curves, the results are as follows : 1 ) the voluminal content of fibre of composite making by vacuum assistant resin injection is more than other composites. 2 ) the mechanical properties of the needlepunching nonwoven fabric reinforced polymer composite are superior to these of the calendering nonwoven fabric reinforced polymer composite
首先，採用不同的增強材料（針刺非織造布和熱軋非織造布） 、不同的基體材料（ 961樹脂和306樹脂）和不同的成型工藝方法（手糊法、真空袋法和真空輔助成型法）製造出了一系列非織造布增強復合材料，然後對它們的拉伸強度、拉仲彈性模量、彎曲強度、彎曲彈性模量和沖擊強度等力學性能進行了測試，並分析了它們的拉伸載荷? ?位移曲線和彎曲載荷? ?位移曲線，結果表明真空輔助成型工藝能大大提高纖維的體積含量；針刺非織造布增強復合材料各項力學性能優于熱軋非織造布增強復合材料。 -
The essay researched the compressive strength, bending strength, impact resistance and abrasion resistance of high strength polypropylene fibermesh concrete the mechanism of enhancing the properties of high strengh poloypropylence fibemesh road concrete composite was discussed and analyzed the regression on tensile strengh with portland cement mixed with fiber was derived using experiment the tensile strength of fiber soil stablization with porland cement was increased with dosage and length of fiber while the former was more effective than the latter test and analysis results indicate that polypropylene fiber can not only reinforce the strength of concrete, but also obviously promote the flexural fatigue life by the great stress the application of polypropylence fiber reinforced concrete in pavement construcion are also introduced
文章研究了不同摻量有機纖維混凝土的抗壓、抗折強度、抗沖及性能、疲勞性能及耐磨性等各種路用性能，綜合論述了有機纖維對水泥混凝土路用性能的影響。通過試驗闡述了纖維水泥混凝土各種路用性能與纖維摻量、長度間的關系。分析表明纖維水泥混凝土隨著纖維摻量和長度增加而增加，且纖維摻量對纖維混凝土抗拉強度的影響比纖維長度的影響更大。 -
The results show that, for flexural - tensile fatigue test and shear fatigue test, the two kinds of structure of common asphalt concrete with strata stress absorbed layer and glass fiber grating had good ability to resist reflection cracking, while the effect of paving asphalt concrete directly on cement concrete slab was worse
結果表明，對于彎拉型疲勞試驗和剪切型疲勞試驗，普通瀝青混凝土下面鋪設strata應力吸收層、玻璃纖維格柵2種結構都具有良好的抗反射裂縫的能力，而在水泥混凝土面板上直接加鋪瀝青混凝土類結構的效果最差。 -
