An Introduction To Biocomposites by Seeram Ramakrishna

By Seeram Ramakrishna

Decades of cumulative study has been carried out at the utilization of fiber-reinforced composites for biomedical program, yet not anyone resource exists the place this subject is handled systematically. This booklet addresses polymer composites utilized to bioengineering in a entire demeanour.

For power functions to achieve success, complete virtue has to be taken of the fabrics homes and the producing ideas to satisfy the desires of biomedical program. This publication makes a speciality of fiber-based composites utilized to bioengineering. It addresses 3 major parts. First, it provides a finished survey of biocomposites from the prevailing literature in quite a few clinical functions, paying specific consciousness to hard-tissue-related implants. moment, mechanical designs and production features of assorted fibrous polymer matrix composites are defined. The 3rd quarter issues examples of the layout and improvement of a number of scientific units and implants utilizing polymer composites.

A basic example of this process is the human skin where dead skin cells on the exterior of the skin are removed by mechanical abrasion while below the skin surface, new cells gather. The balance between renewal and removal is sensitive to external demands and most tissues are capable of adaptive change. The skin provides another example, when a person, who is unused to manual work, begins to use a shovel or other digging implement, the skin on the hands will become thick and coarse. When the same person ceases to use the shovel, the skin on the hands will soften and revert to its earlier state.

Very good damage tolerance. Good in-plane and out-of-plane mechanical properties. Properties High stiffness and strength in 0◦ and 90◦ directions. Poor in-plane shear properties in the case of bi-directional fabrics. Poor interlaminar or through- the-thickness properties. Tendons/ligaments, bone plates, dental post, orthodontic wires, pins, hip joint stem, spine instrumentation, catheters. Comment/Applications Bi-directional woven fabrics are commonly used as reinforcements. Applications include bone plates, artificial limbs, hip joint stem, bone replacement, tibial component of knee joint prosthesis, cartilage prosthesis.
