An overview on 3D printing technology: Technological, materials, and applications

Composites have been found to be the most promising and discerning material available in this century. Presently, composites reinforced with fibers of synthetic or natural materials are gaining more importance as demands for lightweight materials with high strength for specific applications are growing in the market. Fiber-reinforced polymer composite offers not only high strength to weight ratio, but also reveals exceptional properties such as high durability; stiffness; damping property; flexural strength; and resistance to corrosion, wear, impact, and fire. These wide ranges of diverse features have led composite materials to find applications in mechanical, construction, aerospace, automobile, biomedical, marine, and many other manufacturing industries. Performance of composite materials predominantly depends on their constituent elements and manufacturing techniques, therefore, functional properties of various fibers available worldwide, their classifications, and the manufacturing techniques used to fabricate the composite materials need to be studied in order to figure out the optimized characteristic of the material for the desired application. An overview of a diverse range of fibers, their properties, functionality, classification, and various fiber composite manufacturing techniques is presented to discover the optimized fiber-reinforced composite material for significant applications. Their exceptional performance in the numerous fields of applications have made fiber-reinforced composite materials a promising alternative over solitary metals or alloys.

Glass fiber-reinforced polymer composites – a review:

The polymer matrix composites have been widely used for many applications. These are light in weight and easy for manufacturing. The hybrid fiber reinforced composites have been prepared to enhance the mechanical, thermal, damping properties compared to single-fiber reinforced composites. The fiber reinforced hybrid composites consist of two or more fiber in a matrix system. The different fibers were reinforced with suitable matrix for preparing the hybrid composites using various manufacturing methodology. The hybrid composites are used for many application and replacing wood, wood fiber composites and conventional materials. The mechanical properties (tensile, flexural and impact), dynamic, tribological and water absorption properties of natural fiber reinforced hybrid polymer composites and natural/synthetic fiber reinforced hybrid polymer composites were reported.

Hybrid fiber reinforced polymer composites – a review

Growing awareness about eco-friendly materials and environmental regulations have encouraged researchers to use natural resources for structural applications. Natural fibers such as sisal, banana, kenaf, jute, and oil palm are abundantly available; they are cheap and possess superior mechanical properties. Sisal fiber is one of the most promising reinforcements in polymer composites because of its higher tensile strength, modulus and impact strength. Traditionally, sisal fibers were used to make ropes, fancy articles, carpets, etc. There has been growing interest in finding potential structural applications for using sisal fiber-based polymer composites, especially in automobile, marine, and aircraft structures. This chapter addresses developments in sisal fiber-based thermoset and thermoplastic composites and the effects of surface modifications through various treatments. This chapter also deals with the effects of sisal fiber hybridization with other plant and synthetic fibers on mechanical and physical properties.

This study aims to investigate the void content, tensile, vibration and acoustic properties of kenaf/bamboo fiber reinforced epoxy hybrid composites. The composites were made using the hand lay-up method. The weight ratios of kenaf/bamboo were 30:70, 50:50 and 70:30. Further, kenaf and bamboo composites were fabricated for the purpose of comparison. The hybridization of woven kenaf/bamboo reduced the void content. The void contents of hybrid composites were almost similar. An enhancement in elongation at break, tensile strength and modulus of hybrid composites was observed until a kenaf/bamboo ratio of 50:50. Kenaf/bamboo (50:50) hybrid composite displays the highest elongation at break, tensile strength and modulus compared to the other hybrid composites which are 2.42 mm, 55.18 MPa and 5.15 GPa, respectively. On the other hand, the highest natural frequency and damping factors were observed for Bamboo/Kenaf (30:70) hybrid composites. The sound absorption coefficient of composites were measured in two conditions: without air gap and with air gap (10, 20, 30 mm). The sound absorption coefficient for testing without air gap was less than 0.5. Introducing an air gap improved the sound absorption coefficient of all composites. Hence, hybrid kenaf/bamboo composites exhibited less void content, as well as improved tensile, vibration and acoustic properties.
