Hybrid composites were prepared with jute fabric and un-shredded newspaper in polyester resin matrix. The experiment was designed 1:2 weights ratio jute and unshredded newspaper to have 42 (w/w)% fibre content hybrid composites and two different sequences jute/paper/jute and paper/jute/paper of waste newspaper and jute fabric arrangement. Reinforcing material is characterized by chemically, X-ray diffraction methods, Fourier transform infrared spectroscopy and tensile testing. The tensile, flexural and interlaminar shear strength and fracture surface morphology of composites were evaluated and compared. It was found that tensile and flexural properties of the hybrid composite are higher than that of pure paper-based composite but less than pure woven jute composite. The hybridization effect of woven jute fabric and layering pattern effect on mechanical properties of newspaper/woven jute fabric hybrid composites were studied. The test results of composites were analyzed by one-way ANOVA (α=0.05), it showed significant differences among the groups.
采用聚酯树脂基体，制备了黄麻织物和未碎报纸的混杂复合材料。实验设计了黄麻和未碎报纸的重量比为 1:2，纤维含量为 42（w/w）%的混杂复合材料，以及两种不同顺序的废料报纸和黄麻织物排列方式，即黄麻/纸/黄麻和纸/黄麻/纸。采用化学、X 射线衍射、傅里叶变换红外光谱和拉伸试验对增强材料进行了表征。对复合材料的拉伸、弯曲和层间剪切强度以及断裂表面形貌进行了评估和比较。结果表明，混杂复合材料的拉伸和弯曲性能高于纯纸质复合材料，但低于纯机织黄麻复合材料。研究了机织黄麻织物的混杂效应和分层模式对报纸/机织黄麻织物混杂复合材料力学性能的影响。通过单向方差分析（α=0.05）对复合材料的测试结果进行了分析，结果表明各组之间存在显著差异。
