Abstract

A thermal gravimetric analyzer analyzed the thermal adsorption properties of developed composites with the temperature range of 28°C–650°C at a 20°C/min constant heat flow rate. The epoxy hybrid composites were synthesized using natural jute/sisal fibre hybridized with the addition of synthetic E-glass fibres at 0-degree, 0/90-degree, and intralaminar orientations through the wet filament-winding process. The effects of orientations on tensile, flexural, and impact strengths of epoxy hybrid composites were studied using ASTM D3039, D790, and D6110. The evaluated results were compared, and the epoxy hybrid composite containing intralaminar orientations found better thermal stability with reduced weight loss at 650°C. Similarly, the test result for mechanical studies of the hybrid composite showed superior tensile, flexural, and impact strengths. The epoxy hybrid composite with intralaminar orientation was found to have a maximum tensile, impact, and flexural strength of 61.91 MPa, 770.61 J/m, and 83.90 MPa, respectively.

层间黄麻/剑麻/ e-玻璃纤维粘结环氧杂化复合材料绝缘体的热吸附和力学性能评价

热重分析仪分析了复合材料的热吸附性能，温度范围为28℃- 650℃，热流速率为20℃/min。以天然黄麻/剑麻纤维与合成e -玻璃纤维在0度、0/90度和层内方向上进行杂化，通过湿长丝缠绕工艺合成环氧杂化复合材料。采用ASTM D3039、D790和D6110研究了取向对环氧复合材料拉伸、弯曲和冲击强度的影响。对评价结果进行了比较，发现层间取向的环氧杂化复合材料在650℃时具有更好的热稳定性和更低的失重。同样，混合复合材料力学研究的测试结果显示出优越的拉伸、弯曲和冲击强度。层内取向环氧复合材料的最大拉伸强度为61.91 MPa，冲击强度为770.61 J/m，弯曲强度为83.90 MPa。
