Abstract

Purpose The industrial application of continuous glass fabric-reinforced polymer composites (GFRPCs) is growing; however, the manufacturing boundedness of complex structures and the high cost of molds restrict their use. This research proposes a three-dimensional (3 D) printing process for GFRPCs that allows low-cost and rapid fabrication of complex composite parts. Design/methodology/approach The composite is manufactured using a digital light processing (DLP) based Vat-photopolymerization (VPP) process. For the composites, suitable resin material and glass fabrics are chosen based on their strength, stiffness, and printability. Jacob's working curve characterizes the curing parameters for adequate adhesion between the matrix and fabrics. The tensile and flexural properties were examined using UTM. The fabric distribution and compactness of the cured resin were analyzed in scanning electron microscopy. Findings The result showed that the object could print at a glass fabric content of 40 volume%. In DLP-based VPP printing technology, the adequate exposure time was found to be 30 seconds for making a GFRPC. The tensile strength and Young's modulus values were increased by 5.54 and 8.81 times, respectively than non-reinforced cured specimens. The flexural strength and modulus were also effectively increased to 2.8 and 3 times more than the neat specimens. In addition, the process is found to help fabricate the functional component. Originality/value The experimental procedure to fabricate GFRPC specimens through DLP-based AM is a spectacular experimental approach.
使用大桶光聚合增材制造工艺制造连续编织 E 玻璃纤维复合材料
目的 连续玻璃纤维增强聚合物复合材料(GFRPCs)的工业应用正在不断增长;然而,复杂结构的制造限制和模具的高成本限制了其应用。本研究提出了玻璃纤维增强聚合物复合材料的三维(3 D)打印工艺,可低成本、快速地制造复杂的复合材料部件。 设计/方法/途径 采用基于数字光处理(DLP)的蒸镀-光聚合(VPP)工艺制造复合材料。根据强度、刚度和可印刷性,为复合材料选择合适的树脂材料和玻璃纤维织物。雅各布工作曲线表征了基体和织物之间充分粘合的固化参数。使用 UTM 对拉伸和弯曲性能进行了检测。用扫描电子显微镜分析了固化树脂的织物分布和致密性。 结果表明,玻璃纤维织物含量为 40% 时,物体可以进行打印。在基于 DLP 的 VPP 印刷技术中,发现制作 GFRPC 的适当曝光时间为 30 秒。拉伸强度和杨氏模量值分别比非增强固化试样提高了 5.54 倍和 8.81 倍。抗弯强度和模量也分别比未加固的试样有效提高了 2.8 倍和 3 倍。此外,该工艺还有助于制造功能部件。 独创性/价值 通过基于 DLP 的 AM 制作 GFRPC 试样的实验程序是一种引人注目的实验方法。

期刊介绍: Rapid Prototyping Journal concentrates on development in a manufacturing environment but covers applications in other areas, such as medicine and construction. All papers published in this field are scattered over a wide range of international publications, none of which actually specializes in this particular discipline, this journal is a vital resource for anyone involved in additive manufacturing. It draws together important refereed papers on all aspects of AM from distinguished sources all over the world, to give a truly international perspective on this dynamic and exciting area. -Benchmarking – certification and qualification in AM- Mass customisation in AM- Design for AM- Materials aspects- Reviews of processes/applications- CAD and other software aspects- Enhancement of existing processes- Integration with design process- Management implications- New AM processes- Novel applications of AM parts- AM for tooling- Medical applications- Reverse engineering in relation to AM- Additive & Subtractive hybrid manufacturing- Industrialisation
