Modeling of the mechanical behavior of HA/PEEK biocomposite under quasi-static tensile load

Calcium orthophosphate-based biocomposites and hybrid biomaterials

“…The reported ranges of stiffness within 2.8-16.0 GPa and strength within 45.5-69 MPa exceeded the lower values for human bone (7-30 GPa and 50-150 MPa, respectively) [296]. Modeling of the mechanical behavior of HA/PEEK biocomposites is available elsewhere [298].…”

“…Polyetheretherketone (PEEK) [177,179,[293][294][295][296][297][298][299] and high-impact polystyrene [300] were applied to create biocomposites with HA having a potential for clinical use in load-bearing applications. The study on reinforcing PEEK with thermally sprayed HA particles revealed that the mechanical properties increased monotonically with the reinforcement concentration, with a maximum value in the study of 40% volume fraction of HA particles [295][296][297].…”

Biocomposites and hybrid biomaterials based on calcium orthophosphates

“…[349][350][351] A template-driven nucleation and mineral growth process for the high-affinity integration of CDHA with PHEMA hydrogel scaffold has been developed as well. 358 PEEK 225,227,[359][360][361][362][363][364][365]367 and HIPS 366 were applied to create biocomposites with HA because of their potential for clinical use in load-bearing applications. The study on reinforcing PEEK with thermally sprayed HA particles revealed that the mechanical properties increased monotonically with the reinforcement concentration, with a maximum value in the study of ~40% volume fraction of HA particles.…”

“…362 Modeling of the mechanical behavior of HA/ PEEK biocomposites is available elsewhere. 364 Biodegradable poly(α-hydroxyesters) are well established in clinical medicine. Currently, they provide a good choice when a suitable polymeric filler material is sought.…”

The Role of Interphase on Micro- to Macroscopic Responses and Prediction for Initiation of Debonding Damage of Glass—Fiber Reinforced Polycarbonate

“…An improved model, including plasticity, for the prediction of the stress in fibers with an interface/interphase region, clarified that, quite often, the appropriate size of the fibers provides an interphase with a modulus slightly lower than that of the matrix, thereby improving the reliability of the composites (Johnson et al, 2005). The mechanical behavior of a particulate biocomposite with an elasto-plastic matrix has been found to be markedly influenced by interfacial adhesion, which is characterized using the different strengths of the interphase region (Fan et al, 2004). The application of an elastomeric interlayer was also suggested to decrease stress concentration around the fibers (Kardos, 1985).…”
