“…Other researchers have also conducted studies on the preparation and properties of thermoplastic composites reinforced with natural fibers. 15,16 It was found that large number of highly reactive hydroxyl groups on the surface of natural fibers facilitated heterogeneous nucleation, thereby increasing the crystallinity. In addition, the chemical bonds formed between natural fibers and resins enhance the mechanical properties of composites by improving the bonding properties of the interface.…”

Vacuum bagging (VB) technology has become an important method for low-cost preparation of advanced composites materials. In this work, continuous glass fiber-reinforced polyamide-6 (GF/PA-6) composites were successfully manufactured bt VB process, utilizing the anionic polymerization of caprolactam (a monomer of PA-6). The effects of vacuum pressure, curing temperature, curing time on the monomer conversion, crystallinity, and mechanical properties of the composites were investigated by the self-made experimental platform. The results indicated that the number of fiber layers affected the properties of products by affecting the thickness of composites. Vacuum pressure mainly affected the impregnation process of resin on fiber, and the product performance was the best at 1 bar. The flexural strength and flexural modulus of the composites reached the highest when the curing temperature was 150 C and the curing time was 90 min, which were 273.92 MPa and 14.04 GPa respectively, while the interlaminar shear strength (ILSS) was highest at 170 C, up to 42.73 MPa.
