Introduction BFRP bar is made of multi-strand resin matrix material combined CBFS, via extruding and drawing, extrusion molding processes begin from the raw material, and then after soakage, pressing dies, curing, cutting, etc, and finally being a new composite material.
Using the opressive sleeve anchor developed by the researchers,tensile tests of BFRP bars are carried out [12].In test, let it cover the BFRP bars’ in end.Tensile test was done in building materials laboratory of Liaoning Technical University electric-fluid servo compression machines.It is shown in Fig.1.
From the above curve, its tension - deformation after peak intensity, similar to vertical drop.It is different from the steel which exist obviousyield stage.So BFRP bars belong to brittle materials.

Experiment section Sample prepareation.A sample of approximately 3 to 4 grams was required.For materials of different specific gracity,this weight will need to be adjusted to fill the die cavity.If from sheet,the sample needs to be 34mm diameter and 4mm thick.However,samples can also be prepared from pellets or powders.
This method applies to materials containing greater than 20 % fines.In such cases,the relationship between stiffness and dry density or dry unit weight is sensitive to the water content.
V=Poisson's ratio E=Young's modulus,Mpa(kpsi),and G=Shear modulus,Mpa(kpsi) The stiffness and modulus of materials will change with moisture content and can possibly result in hydro-compaction collapse, loss of bearing capacity or loss of effective shear strength.Results obtained from this method are applicable to the evaluation of granular cohesionless materials.

Introduction Wire Electrical Discharge machining (WEDM) is one of the important non-traditional machining processes which are used for machining difficult to machine materials like composites and inter-metallic materials.
Hybrid composites are a class of materials, having two or more discrete particulate reinforcements [3].
Hybrid composites find diversified applications in many engineering fields which are very important in the recent development in material science and acted as replacement for several materials.
Stir casting is liquid state method of composite materials fabrication, in which a dispersed phase is mixed with a molten matrix metal by means of mechanical stirring.

For commercial success, the raw elements of the hydrogen storage materials should be of low cost, the synthesis process should be inexpensive and easily scalable.
In this perspective, cold rolling was investigated as a new means of producing nanocrystalline materials.
This work shows that cold rolling is a promising technique for synthesis of hydrogen storage materials.
