With growing environmental awareness, natural fibers have recently received significant interest as reinforcement in polymer composites.<\/p>\n

Among natural fibers, silk can potentially be a natural alternative to glass fibers, as it possesses comparable specific mechanical properties.<\/p>\n

In order to investigate the processability and properties of silk reinforced composites, vacuum assisted resin transfer molding (VARTM)<\/p>\n

was used to manufacture composite laminates reinforced with woven silk preforms. Specific mechanical properties of silk\/epoxy laminates<\/p>\n

were found to be anisotropic and comparable to those of glass\/epoxy. Silk composites even exhibited a 23% improvement of specific flexural<\/p>\n

strength along the principal weave direction over the glass\/epoxy laminate. Applying 300 kPa external pressure after resin infusion was found<\/p>\n

to improve the silk\/epoxy interface, leading to a discernible increase in breaking energy and interlaminar shear strength. Moreover, the effect<\/p>\n

of fabric moisture on the laminate properties was investigated. Unlike glass mats, silk fabric was found to be prone to moisture absorption<\/p>\n

from the environment. Moisture presence in silk fabric prior to laminate fabrication yielded slower fill times and reduced mechanical properties.<\/p>\n

On average, 10% fabric moisture induced a 25% and 20% reduction in specific flexural strength and modulus, respectively.<\/p>","protected":false},"excerpt":{"rendered":"
