Abstract-The study investigates hybrid biodegradable
Our composite utilizes Hydroxyapatite (HAp) as particulate reinforcement, a calcium phosphate mineral widely applied in biomedical fields like bone grafts and dental implants.
polymer composites incorporating synthetic hydroxyapatite particulate (HAp) sourced from eggshells at varying weights (0%, 3%, 5%, and 7%), alongside fixed PLA (60%), EGlassfibre (40%) compositions, fabricated via the hand lay-up method. HAp, akin to bone structure, is pivotal for bone repair and regeneration, while E-Glassfiber reinforces structural integrity. Test specimens adhere to ASTM standards for hardness, tensile, impact, and flexural tests, crucial for assessing suitability in medical applications. Enhanced mechanical properties are observed in the composite containing 7% eggshell powder particulate.
Eggshells, a rich calcium source, are employed for HAp synthesis due to their availability, cost-effectiveness, and biocompatibility. E-Glass fiber serves as the reinforcement alongside E-Glass Fiber. E-Glass fiber, composed of carbon atoms woven tightly with a polymer resin, offers exceptional mechanical properties, including high tensile strength, stiffness, and fatigue resistance. These reinforcing materials are seamlessly integrated into the polymer matrix.

The composite mentioned above is crafted using the handlayup technique, a traditional and adaptable method in composite manufacturing. This process entails manually layering reinforcement materials like E-Glass fiber into a mold or onto a tool. Subsequently, each layer is infused with resin before undergoing natural or artificial curing to shape .

1 INTRODUCTION Composite materials blend different elements to create a unified structure with enhanced properties, often utilizing fibers, particles, or sheets alongside a polymer matrix. These composites leverage the superior strength and stiffness of fibers, whether metallic, ceramic, or polymerbased, to bear the primary load, complemented by the supportive matrix. The resultant synergy yields materials with superior mechanical traits, applicable across diverse industries like aerospace, automotive, and construction. An emerging trend involves hybrid composites, like E-Glass fiber reinforced polymer matrices, advancing material innovation further. Hybrid composites blend multiple materials for superior mechanical properties, leveraging the shearing effect of fibers. They excel in aerospace, naval, civil, industrial, sporting, and automotive applications. E-Glass fiber, prized for strength and durability, enhances these composites' mechanical performance &versatility. Biodegradable composites offer extensive potential across diverse industries, incorporating natural and synthetic fibers, nanoparticles, and other materials into biodegradable polymer matrices. E-Glass fiber is among the options for reinforcement. Notably, these composites hold promise for novel applications such as body implants.
