“…It was found that the composite with 10% of snail powder exhibited the highest impact strength among the all composites. This could be due to the unique properties of snail powder, such as particle size and shape that positively influenced the composite's mechanical performance [32]. The composite fabricated with 15% snail powder resulted minimum impact strength than 10% of filler material.…”

Hybrid composites are materials composed of a combination of two or more different types of reinforcements, often with distinct properties. The combination of different reinforcements aims to exploit the strengths of each material, resulting in a composite with improved mechanical, thermal, or other specific properties compared to individual components. Nowadays, application of hybrid composites reinforced with natural fibers has gained significance in various industries due to the unique combination of properties such as automobile, aerospace, construction, Sports and Leisure. Eventhough, natural fibers may degrade over time due to environmental factors, resulted in decrease in mechanical properties and overall durability of the hybrid composite. Therefore, Hybrid composites can achieve a combination of high strength, stiffness and toughness that is difficult to obtain with single-fiber composites. The aim of the study is to develop roselle fibers reinforced epoxy resin-based hybrid composite using hand layup method. The snail shell powder with different weight proportion (5, 10 & 15 wt.-%) and 20% (wt.-%) of roselle fiber have been added to fabricate the hybrid composite. The study was carried out in order to study the mechanical properties such as tensile, flexural, impact and hardness strength. The results showed that the composites fabricated with 10% of snail shells powder showed the maximum tensile strength of 40 MPa, flexural strength of 57 MPa and impact strength of 31 KJ/m2. The 15% filler added composite showed the maximum hardness strength of 43 HV. It was observed that the fracture mechanism of a hybrid composite involves fiber breakage, matrix cracking, delamination, matrix debonding, crack initiation and voids etc were formed in the composite. The Composite samples embedded with fillers demonstrate the lowest water intake behaviour. The findings showed that the hybrid composite with 10% snail shell powder exhibited the highest tensile, flexural and impact strength while the 15% snail shell powder composite showed the highest hardness (43 HV). Additionally, snail shell embedded composites demonstrated the lowest water intake behaviour. Fracture analysis revealed mechanisms such as fiber breakage and matrix cracking observed via SEM.

Hydroxyapatite (HA) is a highly biocompatible material that has similar properties to human bone. Researchers have adopted different methods for the synthesis of HA from different natural sources. This paper addresses the synthesis method of nano-hydroxyapatite (n-HA) from Hilsha Fishbone. The synthesized n-HA has been characterized by UV, FTIR, TEM, XRD and cytotoxicity analysis. The successful synthesis of n-HA has been confirmed by the peak formation in the UV analysis. The presence of functional groups has been identified by the FTIR analysis. According to the TEM images, the synthesized n-HA is irregular in size and shape. Based on the XRD analysis, the formation of crystals by the n-HA has been assured. The in-vitro cytotoxicity analysis confirmed the bio-safety of the synthesized n-HA. Based on the findings, the synthesized n-HA can be applied in different biomedical applications.

This review research investigates the potential of Polylactic Acid (PLA)/Hydroxyapatite (HA) composites in bone regeneration, focusing on the composites’ synthesis methods, mechanical properties, and biocompatibility. Through an extensive examination of various preparation techniques, such as solvent evaporation, phase separation, electrospinning, and lyophilisation, the study assesses how these methods influence the physical and biological properties of PLA/HA composites. Significant findings from the review highlight that PLA/HA composites enhance osteoblast activity and proliferation, demonstrating an increase in cell adhesion by up to 25% compared to PLA alone. These composites substantially improve mechanical properties, increasing compressive strength and fracture toughness by approximately 30% and 50%, respectively. These enhancements are pivotal for applications requiring robust, load-bearing materials supporting bone tissue integration and regeneration. In conclusion, due to their optimised mechanical strength, biodegradability, and bioactivity, PLA/HA composites are promising biomaterials for orthopaedic and dental applications. The review suggests future research directions focused on long-term clinical outcomes and further material refinement to maximise clinical efficacy and patient compatibility.
