In case
of BANF and BANC, both have similar UTS values and are higher
than those of bleached pulp. On the other hand, PLA composites
reinforced with modified nano-particles have better UTS than anyother and are slightly better in the case of BADC. With regard to the
strain at fracture, ductility of PLA is decreased when mixed with
more crystalline material, this particularity can be observed with
more clearness in the PLA-BANC composite in which the average
maximum elongation is dropped by an average of 48% from the
unfilled PLA, as the stronger bonds between the highly crystalline
cellulose inhibit the elongation of the fiber.
