Because of their high specific stiffness and strength, fiber reinforced plastics (FRP) are preferred lightweight materials.
However, there are still shortcomings for these materials concerning the insufficient energy absorption in case of failure and the limited opportunities available for the assembly with other components.

High speed emulsifying machine is used to mix raw materials.
Porosity of material has great influence on the elastic modulus of materials, some researches shows that the elastic modulus of the materials decreases linearly with the increase of porosity [13, 14].
So the change of the porosity must be considered in the study of the elastic modulus of materials.
