Abstract
Polylactic acid (PLA) self-reinforced composites (SRCs) are potential alternatives to non-biodegradable plastic composites, but its narrow processing temperature window makes it difficult to manufacture. In this paper, PLA-SRCs with a processing temperature window of more than 50 °C were prepared by stereocomplexation of PLA. In addition, a novel and easy-to-handle solvent-induced interfacial modification of the fibres was developed in order to enhance the mechanical properties of PLA-SRCs. The method controllably generates a porous structure on the fibre surface, which greatly strengthens the interfacial bonding of the composites. After interfacial modification, the interfacial shear strength of PLA-SRCs was increased by almost 40 % while its tensile strength improved by more than 30 %, making this eco-friendly polymer system attractive to many modern industrial applications.
期刊介绍：
Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development.
The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
