From Wikipedia, the free encyclopedia Specific modulus is a materials property consisting of the elastic modulus per mass density of a material. It is also known as the stiffness to weight ratio or specific stiffness. High specific modulus materials find wide application in aerospace applications where minimum structural weight is required.

A composite material is a material made from two or more constituent materials with Concrete is the most common artificial composite material of all and typically consists of rigid, deployable structures; rapid manufacturing; and dynamic reinforcement. The crystalline portion has a higher elastic modulus and provides

In general, the composite elastic modulus increases with the decrease of the mean fiber orientation angle and with the increase of the fiber orientation coefficient; and the elastic modulus increases with the increase of mean fiber length when the mean fiber length is small. When the mean fiber length is large, it has nearly no influence on the elastic modulus of short fiber reinforced composites.

Boron Fiber is an amorphous elemental boron product which represents the major industrial use of elemental free boron. Boron fiber manifests a combination of high strength and high elastic modulus. A common use of boron fibers is in the construction of high tensile strength In the production process, elemental boron is deposited on an even tungsten

The Poisson& 39;s ratio of a stable, isotropic, linear elastic material must be between −1.0 and 0.5 because of the requirement for Young& 39;s modulus, the shear modulus and bulk modulus to have positive values. Most materials have Poisson& 39;s ratio values ranging between 0.0 and 0.5. A perfectly incompressible isotropic material deformed elastically .

The linear portion of the curve is the elastic region and the slope is the modulus of elasticity or Young& 39;s modulus. Many ductile materials including some metals, polymers and ceramics exhibit a yield point. Plastic flow initiates at the upper yield point and continues at the lower one. At lower yield point, permanent deformation is heterogeneously distributed along the sample. The deformation .

During the production of natural fibre reinforced thermoplastics NFRT the which can be processed below the 200 C threshold, are commonly used as the matrix in NFRT. To calculate the elastic modulus of the composite material in the

The utility of specific modulus is to find materials which will produce structures with minimum weight, when the primary design limitation is deflection or physical deformation, rather than load at breaking—this is also known as a 'stiffness-driven' structure. Many common structures are stiffness-driven over much of their use, such as airplane wings, bridges, masts, and bicycle frames.
