据报道,在单向纤维床上用不连续树脂(半浸料)制造的仅含塑料袋(VBO)的预浸料即使在不利的工艺条件下,例如真空差或长的停止时间下,也表现出高的贯穿厚度的渗透性并产生高质量的层压材料。在这项工作中,使用各种编织、纤维类型和面积重量(200-670 GSM)的纤维床制造半浸渍体。生产和表征了平坦和弯曲的层压板,证实了可以使用VBO半浸料从一系列组成材料制造无孔隙部件。尽管观察到预浸料层的体积系数略有增加(Δ Δ φ 0.1),但生产的成型层压板的孔隙率可忽略不计。此外,半预浸料的制造的设计考虑和限制。研究结果表明,聚合物膜去湿可以有效地用于生产半预浸料,通过VBO加工产生无孔隙层压板,赋予预浸料层压板的高压釜外固化的鲁棒性。
Vacuum-bag-only (VBO) prepregs fabricated with discontinuous resin (semi-pregs) on a unidirectional fiber bed reportedly exhibit high through-thickness permeability and yield high-quality laminates, even under adverse process conditions, such as poor vacuum or long out-times. In this work, semi-pregs were fabricated using fiber beds of various weaves, fiber types, and areal weights (200–670 GSM). Flat and curved laminates were produced and characterized, confirming that porosity-free parts can be manufactured from a range of constituent materials using VBO semi-pregs. Contoured laminates were produced with negligible porosity, although a slight increase in bulk factor of prepreg plies was observed (Δ∼0.1). In addition, design considerations and limitations for the fabrication of semi-pregs were presented. The findings demonstrate that polymer film dewetting can be used effectively to produce semi-pregs that yield porosity-free laminatesviaVBO processing, imparting robustness to out-of-autoclave cure of prepreg laminates.
