Abstract

In this work, the epoxy resin cured with chlorinated fluorene amine as the curing agent was obtained, which significantly increased the resin modulus and did not reduce the impact toughness, compared with the common curing system. Al2O3 nanoparticles were used to stiffen the new curing epoxy system, which did not reduce the compression strength of the resin but increased the compression modulus. The microscopic morphology showed that the rigid particles were uniformly dispersed in the resin matrix, and the addition of rigid particles mildly affected the reactional and rheological properties of the resin system. The minimum viscosity of the matrix increased with the additional number of particles. The composite was prepared using the nanoparticle-modified epoxy resin with carbon fiber (CF), and the compression strength of the composite was significantly improved by nearly 30% compared with that composed of the common epoxy system.

碳纤维/环氧纳米粒子复合材料的制备及其压缩力学性能

本工作中，获得了以氯化芴胺为固化剂固化的环氧树脂，与普通固化体系相比，该体系显著提高了树脂模量，但不降低冲击韧性。使用Al2O3纳米颗粒对新的固化环氧树脂体系进行硬化，这并没有降低树脂的压缩强度，但增加了压缩模量。微观形貌表明，刚性颗粒均匀分散在树脂基体中，刚性颗粒的加入对树脂体系的反应性能和流变性能有轻微影响。基质的最小粘度随着颗粒数量的增加而增加。使用纳米颗粒改性的碳纤维环氧树脂制备了复合材料，与普通环氧体系相比，复合材料的抗压强度显著提高了近30%。

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.
