摘要

由于天然纤维增强复合材料具有密度小、宽高比好、可生物降解和易于制造等特点,因此被用于各种结构设计产品,从土木工程到汽车生产。对天然纤维和复合材料的热性能也进行了研究。用热重分析法(TGA)测定了不同纤维负荷下酚醛树脂复合材料和未经处理的Aak纤维增强复合材料的热降解动力学特性。Flynn-Wall法测定了各组分及复合材料的精确表观活化能(Ea)。使用不同的纤维负荷(5、10、15、20 wt.%)来增强PF树脂,并对所有复合材料样品进行TGA测定。通过对TGA数据的观察发现,当纤维负荷为15%时,复合材料的热稳定性达到最大,并得出复合材料的热稳定性随纤维负荷的增加而增加的结论。在15 wt%之后,它开始下降。

TGA and Thermal Kinetics of Raw Calotropis Procera Fiber Reinforced PF Composites
Natural fibre-reinforced composites are used in various structurally designed goods, from civil engineering to the production of automobiles, thanks to qualities like minimal density, a favourable aspect ratio, biodegradability, and ease of fabrication. The thermal behaviour of natural fibres and composites has also been researched. The thermal degradation kinetics characteristics of composites made with phenol formaldehyde resin and reinforced with untreated Aak fibre with varying fibre loads have been determined using thermogravimetric analysis (TGA). The Flynn-Wall procedure determined each component and composite material's precise apparent activation energy (Ea). Varying fibre load (5, 10, 15, 20 wt.%) was used to reinforce PF resin, and TGA was taken for all composite samples. By observing TGA data composite with 15 wt% fibre load shows maximum thermal stability, it can also be concluded that the thermal stability of prepared composites increases with increasing fibre load. After 15 wt%, it starts to decrease.

期刊介绍: The Journal of Condensed Matter Nuclear Science is an open-access electronic journal that accepts scientific papers of high quality concerned with subjects relating to nuclear processes in condensed matter. Papers may focus on the results of experimental studies, theoretical studies, or a combination of these. Topics to which the journal is addressed include:- Calorimetry, energy production in metal hydrides and deuterides; Correlations, or lack of correlations, between energy production and possible nuclear products Materials science issues that are important for the development of nuclear effects in condensed matter Electrochemical issues concerning loading, surface chemistry, resistance diagnostics and other issues concerning metal hydrides and metal deuterides Observations of nuclear products, charged particles, neutrons, tritium, X-ray and gamma emission in metal hydrides Production of new elements or isotopes in metal hydrides and metal deuterides; and modification of isotopic distributions Induced radioactivity in metal deuterides and metal hydrides Accelerator experiments on metal deuterides and metal hydrides Models for nuclear processes in the condensed matter.
