Carbon fibers are fibers composed mostly of carbon atoms and have a diameter of about 3-15 micrometers. The carbon atoms are bonded together in crystals, which are aligned parallel to the long axis of the fiber. This alignment gives the fiber a high strength-to-volume ratio.

Nearly 10 million individuals above the age of 50 suffer from hip, spine, or wrist fractures at some point in life. An additional 33.6 million individuals develop low bone mass and are at risk of osteoporosis. The growing number of complications related to bone-associated disorders such as fractures, traumas, bone infections, and bone tumors has led to the increasing demand for bone void fillers. The bone void fillers have become an indispensable tool for surgeons to manage and treat bone disorders. With the growing prevalence of bone-related diseases and accidents, many leading companies are introducing innovative solutions to provide patients with highquality bone void fillers to achieve the best outcomes.

Adhesive is a substance particularly used to bond two surfaces together. Adhesives have strong shear and tensile strength, making them viable bonding materials for high-pressure situations. There are two general types of adhesives i.e. structural and non-structural. Sealants are paste-like substances that block the flow of fluids through a surface, gap or joint by filling all the spaces between two separate substrates. Sealants usually consists of elastomer, which gives them a paste-like consistency. Examples of sealants can be acrylic systems, silicones, and urethane. Adhesives and sealants are applicable for bonding a wide range of materials, including plastics, metals, ceramics, and composites. Adhesives and sealants are highly preferred in packaging, construction, and automotive industry.

Ultra High-performance Concrete (UHPC) is also known as reactive powder concrete (RPC). It is typically formulated by combining supplementary cementitious materials, Portland cement, reactive powders, limestone and or quartz flour, fine sand, high-range water reducers, and water. The Ultra High-Performance Concrete (UHPC) offers better compressive strength than other concrete materials. The minimum specified compressive strength of UHPC is 17,000 pounds per square inch (120 MPa), and the maximum specified compressive strength is 29,000 pounds per square inch (psi) (200 Mpa).
