Effect of fiber orientation and elevated temperature on the mechanical properties of unidirectional continuous kenaf reinforced PLA composites
Original language description
Limitation in practical applications of biopolymer-fiber composite is mainly at higher temperatures. Thus, this study highlights the effects of fiber orientation on the durability of polylactic acid (PLA) reinforced with unidirectional (UD) continuous kenaf fibers at elevated temperatures. PLA and long kenaf fiber were fabricated using the hot-pressing method and stacked at fiber orientations of 0o, 45o, or 90o, relative to the tensile force. Dynamic mechanical analysis of the composites shows excellent anti-shock and temperature-resistant properties of the composite. UD PLA-kenaf composites with a 0o fiber orientation showed an ultimate tensile of TILDE OPERATOR+D91190 MPa and a flexural strength of TILDE OPERATOR+D91235 MPa, and the strength of the composite was able to retain up to 120oC temperature. The debonding behavior of the fiber from the matrix (fiber pull-out) supported by microscopy proved that interfacial failure occurs from the local strains, which initiate cracking. Interfacial failure and stress transfer have caused a remarkable reduction in composite strength when fibers were oriented at 90o. Hence, this current improvement in the performance of the UD PLA-kenaf fiber composite may potentially replace conventional synthetic fibers, especially for structural automotive applications.
