“…Zhao et al prepared carbon fiber reinforced HAP composite scaffold with excellent mechanical properties and biological activities by spark plasma sintering (SPS) to achieve rapid sintering, and the results indicated that HAP grain size was smaller compared with the one prepared by the traditional sintering method. [52] Ravoor et al fabricated multiwalled carbon nanotubes (MWCNTs) reinforced HAP scaffold by vacuum sintering at 1000 °C for 15 min to inhibit exaggerated grain growth and obtain grain structures, and they found that the scaffold compressive strength was matched with the compressive strength of cancellous bone. [57] However, the microstructure of sintered specimens obtained by this method is not uniform, which affects the mechanical properties of ceramic artificial bone, and the production efficiency is low and the cost is high.…”

It is an urgent need that defect repair can develop from simple device fixation to living tissue reconstruction, from short life function replacement to permanent regeneration repair. At present, bone transplantation has become the second largest transplantation surgery after blood transfusion, and artificial bone transplantation generates great hope for the repair and treatment of bone defect. In order to repair bone defect, artificial bone must have good biological properties and sufficient mechanical properties, and it should also have the shape matching to bone defect site and the connected porous structure. For structures and properties requirements of artificial bone, in this review three major challenges faced by artificial bone transplantation are systemtically analyzed and current methods and strategies to address these issues are discussed: 1) the need for developing a type of bone scaffold material with both biological and mechanical properties, 2) the need for realizing the controllable fabrication of individual shape and multistage pore structure of bone scaffold, 3) the need for realizing the transformation from man‐made structure to biological structure. Besides, it summarizes the advantages and disadvantages of these methods and discusses the potential future directions of structural and functional adaptive artificial bone for bone defect regeneration.

“…[1][2][3] However, it cannot be used directly owing to the fragility and particular structure of CF. [4][5][6] In industry, CF and polymer matrix are usually combined to form carbon fiber-reinforced polymer (CFRP) matrix composites, which have the properties of CF with the characteristics of the polymer matrix. CFRP have been extensively studied in academia and industry because of their excellent corrosion resistance and structural designability.…”

A kind of silicone rubber (SR)/carbon fiber (CF)@polydopamine (PDA) flexible composites were prepared in this work. CF was modified by oxidative self‐polymerization of dopamine (DA), and the effect of DA concentration on properties of SR/CF@PDA composites was researched. The transverse fiber bundle tests have shown that SR/CF@PDA‐1.5 has the best interfacial bonding performance. Compared with SR/CF, tensile strength and elongation at break of SR/CF@PDA‐1.5 were increased by 61.7% and 68.4%, respectively. Results indicate that the interfacial bonding of SR/CF@PDA composites was effectively improved due to the adhesion properties of PDA. Moreover, the rough surface of CF@PDA also enhanced the interface interaction through physical “interlocking.” When being compared to other surface modification process, dopamine‐modified carbon fiber is cost effective, “green” and highly efficient. SR/CF@PDA with an excellent interfacial bonding and flexibility is a kind of wrapping material for protection of special precision instruments.

“…In the last century, an intense research effort has been devoted to the reinforcement of bioceramics for different applications. In this respect, various approaches have been proposed, including modified sintering treatments [51][52][53], combination with polymeric phases to produce composites [49,54,55], the addition of fibers or the development of additive manufacturing as a 3D technique to prepare complex-shaped bioceramic structures [34,[56][57][58][59][60]. A major approach to this purpose is the addition of ceramic particles, whiskers, and fibers to the ceramic matrix to improve the fracture toughness [61][62][63][64][65].…”

Toughening of Bioceramic Composites for Bone Regeneration

et al. 2021

View full text Add to dashboard Cite

Bioceramics are widely considered as elective materials for the regeneration of bone tissue, due to their compositional mimicry with bone inorganic components. However, they are intrinsically brittle, which limits their capability to sustain multiple biomechanical loads, especially in the case of load-bearing bone districts. In the last decades, intense research has been dedicated to combining processes to enhance both the strength and toughness of bioceramics, leading to bioceramic composite scaffolds. This review summarizes the recent approaches to this purpose, particularly those addressed to limiting the propagation of cracks to prevent the sudden mechanical failure of bioceramic composites.
