Size Effect of CaCO3 Filler on the Mechanical Properties of SMC Composites Y.
Among them, filler is one of the important factors for improving mechanical and thermal properties of composites, but it has not drawn much attention for SMC composites.
The particle size of filler affected the mechanical properties of composites as much as its content, because it influences the density and viscosity of the compounds.
So, in this work, the mechanical properties of SMC were studied with ground calcium carbonates in different particle size.
The filler condition has an influence on the mechanical properties of composites.

Software Implementation of the Algorithm the Statistical Straggling of the Mechanical Properties of Materials in the Design of Structures Galina G.
Introduction In the design of structures and facilities conventionally for any construction structure the average indications of mechanical properties are applied, and the estimation of the impact of various external factors on building and structures is based on some idealized homogeneous material with pre-determined physical and mechanical properties.
(2) The option of mechanical properties straggling for a particular material property is activated (fig.3).
In other words, stiffness factors (or, factors of rigidity) , in their determinative relationship, revealed discontinuous change when cracking started.
As the results of the numerical calculation, the dispersion properties of the material affects the maximum and stress: SX and the von Mises equivalent stress SEQV (fig.7).

But the excessive alkali treatment will remove too much lignin and hemicelluloses in the fiber cells, mechanical properties of the composite material will be affected
By the range analysis, table 4 and figure 2 show that the major factor affecting compressive strength is the alkali treatment of the fiber
By range analysis, the table 4 and figure 3 show that the major factor affecting tensile strength is the degree of alkali treatment of the fiber.
Excessive alkali treatment will remove too much lignin and hemicelluloses in the fiber cells, and the mechanical properties of the composite material will be affected for the toughness decrease of fiber.
