Which is an effect of fillers in composite is:

Fillers in composite Generally between 30% to 70% by volume or 50% to 85% by weight of a composite Benefits of Fillers Reinforcement- compressive strength, tensile strength, modulus of elasticity (i.e., stiffness or rigidity), and toughness Reduction of polymerization shrinkage/contraction Reduction in thermal expansion and contraction Control of workability/viscosity Decreased water sorption Imparting radiopacity
