Abstract
Considering that biomimetic Bouligand structure can simultaneously improve strength and toughness and fiber can guide crack propagation path in fiber reinforced composites, unique 3D (spatial) Bouligand structural composites where crack deflection, twisting, and branching are more likely to occur compared to 2D (planar) ones were constructed by a convenient and reliable preparation method. Compressive strength and flexural strength of biomimetic continuous carbon fiber reinforced hydroxyapatite (CF/HA) composites with spatial Bouligand (SB) structure respectively increase by 85.55 % and 38.42 % compared to those of the composites with a common planar Bouligand (PB) structure. The 3-dimensional stacked Bouligand structure causes further crack deflection and energy dissipation, resulting in a superior mechanical property over PB structure. Compressive strength (190.2 MPa), flexural strength (78.9 MPa), and fracture toughness (24.4 MPa m1/2) of the SB composites can meet the requirements of weight-bearing bone, which will allow them to be used for ceramic bone plates and bone nails. This study also offer a facile strategy for the construction of advanced ceramics, metal, and polymer based composites with simultaneously improved strength and toughness.
期刊介绍:
Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
