“…Plant fibers fall into various categories, including ramie, flax, sisal, wood, and grass fibers. Because of their environmentally friendly characteristics, composites reinforced with plant fibers have been widely used in automotive interiors, furniture, and landscape gardening [12,13]. Bamboo (Bambusoideae, the grass family Poaceae) is particularly abundant in Asia, especially in China.…”

The demand for eco-friendly renewable natural fibers has grown in recent years. In this study, a series of polypropylene-based composites reinforced with single bamboo fibers (SBFs), prepared by non-woven paving and a hot-pressing process, were investigated. The influence of the content of SBF on impact strength, flexural strength, and water resistance was analyzed. The properties of the composites were greatly affected by the SBF content. Impact strength increased as SBF content increased. The modulus of rupture and modulus of elasticity show an optimum value, with SBF contents of 40% and 50%, respectively. The surface morphology of the fractured surfaces of the composites was characterized by scanning electron microscopy. The composites showed poor interfacial compatibility. The water resistance indicates that the composites with higher SBF contents have higher values of water absorption and thickness swelling, due to the hydrophilicity of the bamboo fibers. The thermal properties of the composites were characterized by thermal gravimetric analysis and by differential scanning calorimetry. The thermal stability of the composites was gradually reduced, due to the poor thermal stability of SBFs. In the composites, the maximum decomposition temperature corresponding to SBF shows an increasing trend. However, the maximum decomposition temperature of polypropylene was not influenced by SBF content. The melting point of the polypropylene in the composites was lower relative to pure polypropylene, although it was not affected by increasing SBF content.

“…The thermoset matrices have low process temperature compatible with the thermal stability of the natural fibres allowing to preserve them during the processing [10]. The polyepoxy (EP) was highly investigated [11][12][13][14]. Jain et al [15] have shown the improvement of the mechanical properties due to the use of bamboo mats.…”

“…Furthermore, the impact response of such composites is strongly affected by the fibers-matrix interfacial bond strength in unidirectional laminates. 36 As a result, the higher volume fraction of fibers in PPLGF and acceptable fiber/matrix bonding result in higher impact strength compared to other composites (Figure 18). The PPLGF and PPLGFY composites shown a remarkable impact strength of 162normal ±normal 5 kJ/m 2 and 68normal ±normal 5 kJ/m 2 , respectively, which were about 7 and 3 times larger than the PPSCGF.…”

“…In general, fiber characteristics such as type, orientation and volume fraction play an important role in the impact properties of glass fiber reinforced PP composites. Furthermore, the impact response of such composites is strongly affected by the fibers-matrix interfacial bond strength in unidirectional laminates [36]. As a result, the higher volume fraction of fibers in PPLGF and acceptable fiber/matrix bonding result in higher impact strength compared to other composites ( Figure 18).…”

Mechanical properties and manufacturing processes of Glass Fiber/Polypropylene (GF/PP) composites for application of flexible internal long bone fracture fixation plates have been investigated. PP/Short Chopped Glass Fiber (PPSCGF), PP/Long Glass Fiber (PPLGF) and PP/Long Glass Fiber Yarn (PPLGFY) were used in fabrication of the fixation plates. The PPSCGF and PPLGF plates were made by the heat-compressing process and Three-dimensional (3D) printing method was used to make the PPLGFY ones. The values of Young’s modulus, tensile strength, flexural modulus and strength, and impact strength of the PPSCGF in the fiber longitudinal direction were found to be [Formula: see text]GPa, [Formula: see text]MPa, [Formula: see text]GPa, [Formula: see text]MPa and [Formula: see text]kJ/m2, respectively. Where, these values for the PPLGF were to [Formula: see text]GPa, [Formula: see text]MPa, [Formula: see text]GPa, [Formula: see text]MPa, and [Formula: see text]kJ/m2 and for the PPLGFY were to [Formula: see text]GPa, [Formula: see text]MPa, [Formula: see text]GPa, [Formula: see text]MPa and [Formula: see text]kJ/m2. These have been found to be in close agreement with the human bone properties. Furthermore, the strength and modulus values of the plates were reasonable to be used as a bone implant applicable for bone fracture reconstructions. Hence, the study concluded that the GF/PP composites are useful for load-bearing during daily activities and would be recommended as a choice in orthopedic fixation plate applications. It will help the researchers for development of new fixation designs and the clinicians for better patient’s therapy in future.
