Abstract

The research study has focused on the influence of Kevlar fiber surface positions of fibers. The phosphoric acid (PA) pretreated epichlorohydrin (ECH) treatment was used for surface modification of Kevlar fiber. Flexural after indentation (FAI) evaluations were carried out on inter-intraply treated and untreated Kevlar hybrid composites. The surface characterizations of treated and untreated Kevlar samples were investigated by X-ray photoelectron spectroscopy (XPS), XRD, and FESEM analysis. The results revealed that the load-bearing capacity and flexural strength of intraply hybrid composites increased by 45.1% and 36.5%, respectively, compared to interply hybrid composites. Also, the indentation strength of the treated Kevlar intraply hybrid composites was 26.4% higher than that of the untreated intraply hybrid composites. Further, it was analyzed by damage progression and fractography analysis by field emission scanning electron microscopy.

纤维表面处理和杂化对层间和层内 Kevlar 增强聚合物复合材料的影响

研究重点是纤维表面位置对 Kevlar 纤维的影响。采用磷酸（PA）预处理环氧氯丙烷（ECH）处理法对 Kevlar 纤维进行表面改性。对经过间歇处理和未处理的 Kevlar 混合复合材料进行了压痕后挠曲（FAI）评估。通过 X 射线光电子能谱 (XPS)、XRD 和 FESEM 分析研究了处理过和未处理过的 Kevlar 样品的表面特征。结果表明，与层间混合复合材料相比，层内混合复合材料的承载能力和抗弯强度分别提高了 45.1%和 36.5%。此外，经过处理的 Kevlar 内层混合复合材料的压痕强度比未经处理的内层混合复合材料高出 26.4%。此外，还利用场发射扫描电子显微镜对损伤进展和断口进行了分析。

期刊介绍： The Journal of Reinforced Plastics and Composites is a fully peer-reviewed international journal that publishes original research and review articles on a broad range of today''s reinforced plastics and composites including areas in: Constituent materials: matrix materials, reinforcements and coatings. Properties and performance: The results of testing, predictive models, and in-service evaluation of a wide range of materials are published, providing the reader with extensive properties data for reference. Analysis and design: Frequency reports on these subjects inform the reader of analytical techniques, design processes and the many design options available in materials composition. Processing and fabrication: There is increased interest among materials engineers in cost-effective processing. Applications: Reports on new materials R&D are often related to the service requirements of specific application areas, such as automotive, marine, construction and aviation. Reports on special topics are regularly included such as recycling, environmental effects, novel materials, computer-aided design, predictive modelling, and "smart" composite materials. "The articles in the Journal of Reinforced Plastics and Products are must reading for engineers in industry and for researchers working on leading edge problems" Professor Emeritus Stephen W Tsai National Sun Yat-sen University, Taiwan This journal is a member of the Committee on Publication Ethics (COPE).
