Abstract

Composites were manufactured from glass fiber, bagasse fly ash, and epoxy matrix and examined their mechanical and physical properties. The percentages of bagasse fine ash, glass fiber, and matrix were designed at 10%, 15%, 20%, 25%, and 30% with 30% glass fiber and conducted density, flexural strength, hardness, absorption of water, and swelling properties of thickness. Composites were prepared by manual layering. ASTM standards were followed in preparing the samples. According to the results, the bagasse fine ash percentage variation was significant in the composite but had no linear effects on its hardness and flexural strength. A 20% bagasse fine ash composite had the highest flexural strength and hardness at 27.65 MPa and 52.86 HRA, respectively, which are significantly (>0.002) higher than composites of 30% bagasse fine ash, along with the highest density. This study measured water absorption and swelling of composite samples immersed in distilled water for 192 h. As the bagasse ash content increases, these values were linearly increased until saturation occurs.
研究蔗渣灰分体积变化对环氧树脂基增强玻璃纤维复合材料性能的影响
以玻璃纤维、甘蔗渣粉煤灰和环氧树脂为基体制备复合材料,并对其力学性能和物理性能进行了测试。蔗渣细灰、玻璃纤维和基质的掺量分别为10%、15%、20%、25%和30%,其中30%的玻璃纤维和传导密度、抗弯强度、硬度、吸水率和厚度的膨胀性能。采用人工分层法制备复合材料。样品的制备遵循ASTM标准。结果表明,蔗渣细灰分在复合材料中的含量变化显著,但对复合材料的硬度和抗弯强度没有线性影响。20%甘蔗渣细灰复合材料的抗弯强度和硬度最高,分别为27.65 MPa和52.86 HRA,显著高于30%甘蔗渣细灰复合材料(>0.002),且密度最高。本研究测量了复合材料样品在蒸馏水中浸泡192 h后的吸水率和溶胀率。随着甘蔗渣灰分含量的增加,这些数值呈线性增加,直至饱和。
