Kevlar-based protective gear is often considerably lighter and thinner than equivalent gear made of more traditional materials. [26] Kevlar is a very popular material for racing canoes. It is used for motorcycle safety clothing, especially in the areas featuring padding such as the shoulders and elbows.
Friability testing is a laboratory technique used by the pharmaceutical industry to test the durability of tablets during transit. This testing involves repeatedly dropping a sample of tablets over a fixed time, using a rotating wheel with a baffle.
A hip implant is an example of an application of biomaterials. A biomaterial is a substance that has been engineered to interact with biological systems for a medical purpose – either a therapeutic (treat, augment, repair, or replace a tissue function of the body) or a diagnostic one.
The strength of a material is defined as the maximum stress that can be endured before fracture occurs. Strength of biomaterials (bioceramics) is an important mechanical property because they are brittle. In brittle materials like bioceramics, cracks easily propagate when the material is subject to tensile loading, unlike compressive loading.
This combination mixes the properties of the fiber with the matrix to create a new material that may be stronger than the fiber alone. When combined with polymers, cellulose fibers are used to create some fiber-reinforced materials such as biocomposites and fiber-reinforced plastics. The table displays different polymer matrices and the ...
A general name for this class of material is biological materials. Biomolecules are an important element of living organisms. Biomolecules are an important element of living organisms. They are often endogenous , [ 2 ] i.e. produced within the organism, [ 3 ] but organisms usually also need exogenous biomolecules, for example certain nutrients ...
Alternatively, the bioceramic materials can be doped with β-emitting materials and implanted into the cancerous area. [2] Other trends include engineering bioceramics for specific tasks. Ongoing research involves the chemistry, composition, and micro- and nanostructures of the materials to improve their biocompatibility. [16] [17] [18]
It is not given that bio-based materials always perform better than fossil-based materials. [15] [16] Their environmental performance depends on a series of factors, related to the sourced material and to the amount and typology of manufacturing processes the raw natural material need to undergo to become a bio-product.
