摘要

快速成型技术提高了复杂零件的生产效率。然而,机械性能降低等固有缺陷仍是挑战,需要进一步改进以缩小差距并满足行业需求。因此,本研究调查了玻璃纤维编织物与大桶光聚合打印技术的结合使用情况,以获得具有优异机械性能的复合材料零件。这种方法无需固化工序或真空灌注,因此具有缩短纤维增强复合材料生产时间的优势。研究人员使用挠曲、层间剪切(ILSS)、不同纤维取向和纤维体积分数的冲击试验,对使用这种方法制造的复合材料板的机械性能进行了研究。机械测试结果表明,最大弯曲强度为 295 兆帕,冲击强度为 174 kJ/m2,层间剪切强度为 20.58 兆帕。此外,还对印刷部件的横截面进行了光学成像,结果显示纤维的润湿均匀且良好。研究结果表明,大桶印刷玻璃纤维编织物是一种很有前景的方法,可用于生产具有更高机械性能和更低生产率的复合材料部件。通过逐层制造缩短了生产时间并减少了微观结构。最大弯曲强度:295 兆帕、冲击强度:174 kJ/m2、ILSS:20.58 兆帕。随着层数的增加,孔隙率值保持一致。有望生产出性能更好的标准厚复合材料。

Examine the mechanical properties of woven glass fiber fabric reinforced composite plate manufactured with vat‐photopolymerization
Additive manufacturing has enhanced the production of complex parts with greater efficiency. However, inherent drawbacks such as reduced mechanical properties still pose challenges, necessitating further improvements to bridge the gap and meet industry demands. Therefore, this study investigated the use of glass fiber woven fabric with vat‐photopolymerization printing to achieve composite parts with superior mechanical properties. This approach offered an advantage in reducing the production time required for fiber‐reinforced composites by eliminating the need for curing processes or vacuum infusion. The mechanical properties of the composite panels manufactured with this method were investigated using flexural, interlaminar shear (ILSS), impact tests with different fiber orientations, and fiber volume fractions. The results of the mechanical tests showed maximum flexural strength of 295 MPa, impact strength of 174 kJ/m2, and ILSS of 20.58 MPa. In addition, optical images were taken to examine the cross‐section of the printed parts, which revealed a uniform and good wetting of the fibers. The findings suggest that glass fiber woven fabric in vat printing is a promising approach for producing composite parts with enhanced mechanical properties and reduced production rate.Highlights Additive manufacturing of glass fiber woven fabric reinforced with VPP printing. Reduced production time and microstructure by using layer‐by‐layer manufacturing. Maximum flexural strength: 295 MPa, impact strength: 174 kJ/m2, ILSS: 20.58 MPa. Consistent porosity values with the increasing number of layers. Promising for producing standard and thick composites with improved properties.
