Multilayer biocomposites of PLA woven fabric and PBS sheets using compression molding process

Abstract

Biocomposite materials play an important role to replace the conventional polymer composites in the issue of serious environmental problems from the end‐used products. The relationship between the design and construction of biocomposites structure and their properties is an important factor to the composite application. In this study, the biocomposites of poly(butylene succinate) (PBS) reinforced with poly(lactic acid) (PLA) woven fabric to improve mechanical properties of PBS matrix was fabricated by compression molding process. The plain weave PLA woven fabrics showed higher tensile strength (28.9%) and modulus (21.5%) than the twill 2/2 weave pattern. However, the flexural strength and modulus of composites reinforced with multi‐layers PLA woven fabric are higher than the one‐layer reinforcement (57% and 31%, respectively). The impact and peel strength of PLA twill 2/2 weave biocomposite are higher than the plain weaving. The mechanical property of matrix reinforced with plain structure was found to increase on the vertical axis while the twill weaving showed the increase on horizontal axis adhesion between the reinforced PLA woven fabric and the PBS matrix.

Novel okra woven fabric reinforced polylactic acid composites: Mechanical, morphological, and thermal properties

“…Woven materials are flexible, adaptive, and have intrinsic features due to their weaving structures. Woven fabric‐based composites provide superior symmetrical qualities at 0° and 90° angles compared to unidirectional laminates, 13–15 a crucial aspect in engineering applications 12,16 . Due to their high specific strength, formability, and dimensional stability, woven fabrics are preferred over knitted and nonwoven fabrics in reinforcing composites 17–19 .…”

“…Woven fabric-based composites provide superior symmetrical qualities at 0 and 90 angles compared to unidirectional laminates, [13][14][15] a crucial aspect in engineering applications. 12,16 Due to their high specific strength, formability, and dimensional stability, woven fabrics are preferred over knitted and nonwoven fabrics in reinforcing composites. [17][18][19] Interlacement of woven fabric enhances strength more than fiber-matrix adhesion; hence researchers have expressed a keen interest in exploring the potential of these fabric structures.…”
