Abstract

Poly(ether-ketone)/fly ash (FA) composites reinforced with 0-30 wt% FA were fabricated using ball milling followed by hot compaction. The composites were investigated for mechanical and viscoelastic properties. Scanning electron microscopy revealed excellent dispersion and good adhesion of FA particles with the matrix. The addition of FA increased the microhardness by 70% and the storage modulus (below glass transition) by 75%. The reinforcing efficiency was better above the glass transition, which increased to around 177% at 250°C. This research indicates that the FA can be used as an alternative reinforcement of costly ceramic powder for the electronic packaging substrate or printed circuit board applications.

粉末冶金法制造的聚（醚酮）/粉煤灰复合材料的粘弹性行为

采用球磨法和热压实法制造了 0-30 wt% FA 增强的聚（醚酮）/粉煤灰（FA）复合材料。对复合材料的机械和粘弹性能进行了研究。扫描电子显微镜显示，FA 颗粒的分散性极佳，与基体的粘附性良好。添加 FA 后，微硬度提高了 70%，储存模量（低于玻璃化转变）提高了 75%。玻璃化转变以上的强化效率更高，在 250°C 时增至约 177%。这项研究表明，在电子封装基板或印刷电路板应用中，FA 可用作昂贵陶瓷粉末的替代增强材料。

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
