摘要/Abstract

摘要： 由于经编织物在成本和性能上具有巨大优势,已被广泛应用于能源、交通、飞行器、运动器材等领域。针对双轴向(+45/-45)碳纤维经编织物层板,采用真空辅助树脂传递模塑(VARTM)工艺制备了[(45/-45)/(0/90)]_2s(Layup-1)和[(60/-30)(-60/30)(0/90)]_s(Layup-2)两种不同厚度和铺层的层合板,并检测了板的成型质量和纤维体积含量;研究了两种层合板的落锤冲击性能和冲击后的压缩强度。结果表明,通过合理控制工艺参数,可以制备出成型质量均匀且纤维体积含量可达54.2%的层合板。并且,Layup-1层合板可承受更高的冲击载荷,并具有较高的剩余压缩强度。而Layup-2层合板具有更大的抵抗冲击变形的能力和吸收更多冲击能的能力,在冲击过程中具有明显的损伤发生和损伤累积过程,但其冲击后的压缩强度比Layup-1稍低。

Abstract: Multi-axial Warpknitting Fabrics (MWK) have been widely used in energy, transportation, vehicle, sports, equipment and other fields due to its great advantages in term of cost and performance. Based on bi-axial (45/-45) MWKs, two kinds of laminates, [(45/-45)/(0/90)]_2s (Layup-1) and [(60/-30)(-60/30)(0/90)]_s (Layup-2), with various layup angles and thicknesses were prepared by using of vacuum assisted resin transfer molding (VARTM). The molding quality, fiber volume fraction, impact and compressive strength after impact of the obtained laminates were measured and evaluated. The results have shown that laminates with uniform quality and 54.2 vol% can be obtained by reasonably controlling the process. The layup-1 possesses larger capacity of anti-impact and compression. While, the layup-2 has larger ability to resist impact deformation and can absorb more impact energy during the impact process. Also, the layup-2 laminate shows significant stage of damage initiation and accumulation, but it′s compressive strength after impact is relatively lower than that of the layup-1.
