The influence of mechanical surface linking and elastic fiber bending on the fiber network strength and elasticity (i.e. storage modulus and critical strain) was investigated for pulps with different lengths and stiffness, using a parallel plate rheometer. Results show that the storage modulus increases and critical strain decreases with increasing fiber length due to increased number of fiber contacts. Laboratory-cooked pulp has a higher storage modulus and a lower critical strain than commercial pulp because of straighter and stiffer fibers, which are more influenced by both mechanical surface linking and elastic fiber bending.
