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.

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.
From the analysis showed in Table 3 and Fig 4, this kind of material have best mechanical properties.
