“…Therefore, how to reinforce gelatin materials becomes a challenge for worldwide researchers. Many attempts such as vapor crosslink, 2 orientation technique, [3][4][5] and gelatin-based composites filled with hydroxyapatite, 6 tricalcium phosphate, 7 and carbon fiber 8 have been made and great progress has been achieved. However, the strength is still not high enough, especially in the wet state.…”

Gelatin/montmorillonite (MMT) hybrid nanocomposite was directly prepared with unmodified MMT and gelatin aqueous solution. Thermal and mechanical properties of the composite were investigated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and tensile tests. The results indicated that an intercalated or partially exfoliated nanocomposite could be achieved, and the properties of the composite were significantly improved. A T g peak of high temperature disappeared in the DSC curve of the composite, and the thermogravity and thermally decomposed rate decreased obviously. The tensile strength and Young's modulus were also improved notably, which varied with MMT content, as well as the pH of gelatin matrix. Meanwhile, SEM photographs showed a plasticizing trend of gelatin fracture surface due to intercalation with MMT. Furthermore, the wet mechanical behavior was initially studied.

“…Several authors have investigated equivalent materials and the most recent attempts have used polymer additives such as poly(lactic acid) (PLA), poly(acrylic acid) (PAAc), collagen, and gelatin due to the efficiency of their contained calcium binding properties (Chang et al, 2003;Schiller et al, 2003;Chian Liou et al, 2003;Spanos et al, 2002). As biomaterial, gelatin displays several attractive: it has not shown antigenity, it is completely resorbable in vivo, its physicochemical properties can be suitably modulated (Yao et al, 1996;Fakirov et al, 1996). Furthermore, its adhesiveness and plasticity properties make gelatin a suitable matrix for ceramic composites.…”

In this study, hydroxyapatite (HAp) and gelatin (GEL) scaffolds were prepared to mimic the mineral and organic component of natural bone. The raw material was first compounded and resulting composite were molded into the petridishes. Using Solvent casting process, it is possible to produce scaffolds with mechanical and structural properties close to natural trabecular bone.The mechanical properties of composites were investigated by Thermo-mechanical analyzer (TMA), Vickers microhardness tester, Universal testing machine. It was observed that the composite has maximum tensile strength of 37.13MPa ( oven drying) and % elongation of 7.68 (Oven drying) and 2.04 (Natural drying) at 15% of Hap respectively. These results demonstrate that the prepared composite scaffold is a potential candidate for bone tissue engineering.

“…2 Several studies have elucidated that mechanical properties of gelatin can be improved and adjusted. [3][4][5][6] Recently, composites composed by gelatin and inorganic materials, such as tricalcium phosphate and hydroxyapatite, have been reported. 2,7 We have reported the preparation of gelatin-based composites reinforced, respectively, with chopped (short) and continuous (long) carbon fibers in the first part of this series of articles, 8 where the emphasis has been given to the mechanical properties of gelatin-based composite, as a function of fiber volume fraction (Vf), gelatin content, and plasticizer content.…”

Carbon fiber-reinforced gelatin composites have been prepared in our laboratory to obtain a novel biomaterial of improved mechanical properties. The swelling behavior (swelling rate, swelling kinetics, maximum solvent uptake, etc.) for both continuous carbon fiber-reinforced gelatin composite (C L /Gel) and short carbon fiberreinforced gelatin composite (C S /Gel) are investigated. Experimental data show that the swelling process of the original gelatin and gelatin matrixes in both composites follows a second-order kinetics. The swelling of the gelatin matrixes in both composites proceeds slower than that of the pristine gelatin, and depends on fiber form and fiber volume fraction (Vf). Results indicate that the presence of carbon fibers suppresses the swelling of the gelatin matrixes in both composites. It is found that the gelatin matrix in C S /Gel possesses a smaller swelling rate and maximum solvent uptake than that in C L /Gel. A mechanism governing these phenomena is discussed in this article.
