Abstract

Real service requirements of the assembly performance and joining properties of design components are critical for composite usage in the aerospace industry. This experimental study offers a novel and comprehensive analysis of dry drilling optimization for glass-reinforced, high-performance epoxy matrix composites used in aerospace structures, focusing on thrust force and delamination. The study presents a first-time investigation into the combined effects of spindle speed (1000, 2250, 4000 and 5750 rpm), feed rate (0.2, 0.4, 0.6 and 0.8 mm/rev) and tool diameter (3 and 5 mm) using a custom-designed drill tool specifically developed for this application, filling a gap in the current literature. By employing the Taguchi design of experiments, the study identified that medium spindle speeds (2250-4000 rpm), lower feed rates (0.2 mm/rev) and smaller tool diameters (3 mm) provided optimal conditions for minimizing thrust force and delamination. These results present actionable insights into improving the structural integrity and performance of drilled aerospace-grade composite components, offering innovative advancements in both the aerospace and defense industries.

使用新型设计钻头钻削航空航天结构用高性能玻璃/环氧树脂复合材料时，钻削参数和工具直径对分层和推力的影响

对设计部件的装配性能和连接性能的实际使用要求对于航空航天工业中复合材料的使用至关重要。本实验研究针对航空航天结构中使用的玻璃纤维增强高性能环氧基复合材料的干钻优化进行了新颖而全面的分析，重点关注推力和分层。该研究首次使用专为该应用开发的定制钻具，对主轴转速（1000、2250、4000 和 5750 rpm）、进给率（0.2、0.4、0.6 和 0.8 mm/rev）和刀具直径（3 和 5 mm）的综合影响进行了研究，填补了现有文献的空白。通过采用田口试验设计，研究发现中等主轴转速（2250-4000 转/分）、较低进给率（0.2 毫米/转/分）和较小刀具直径（3 毫米）为最大限度地减少推力和分层提供了最佳条件。这些结果为改善钻孔航空航天级复合材料部件的结构完整性和性能提供了可行的见解，为航空航天和国防工业提供了创新性的进步。

期刊介绍： Polymers (ISSN 2073-4360) is an international, open access journal of polymer science. It publishes research papers, short communications and review papers. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Polymers provides an interdisciplinary forum for publishing papers which advance the fields of (i) polymerization methods, (ii) theory, simulation, and modeling, (iii) understanding of new physical phenomena, (iv) advances in characterization techniques, and (v) harnessing of self-assembly and biological strategies for producing complex multifunctional structures.
