  • Abstract:

Despite the effectiveness and advantages of natural ?bres as reinforcement in the production of composite materials, it
has been observed that natural ?bres have highaf?nityfor moisture absorption and this can weaken the properties of
the developed composites. So, there is need to modify the properties of the ?bres so as to reduce the rate of absorption of
moisture that pose advert effect on the mechanical properties when they are incorporated into materials for composite
production. In this research, white chicken ?bres from chicken feathers were mercerized and utilized to reinforce high
density polyethylene HDPE for structural applications. The white chicken ?bres were extracted from chicken feathers
by trimming after which they were mercerized with 0.1 M NaOH solution. The mercerized and unmercerized ?bres
were analyzed to ascertain their crystallinity index and morphology by using X-Ray diffraction (XRD) and scanning
electron microscopy (SEM), respectively. The composites were developed by varying the ?bres in a predetermined
proportion of;2, 4, 6, 8 and 10 wt% with the HDPE matrix. Compression moulding process was used to produce the
composite samples. The developed composite samples were characterized to ascertain their tensile and ?exural
properties in accordance with ASTM D3038M-08 and ASTM D7264M-07 standards, respectively. The morphology of
the developed composites wasalso analyzed and it revealed that mercerization of the chicken feather ?bres are
potential means of enhancing the properties of their corresponding composites. From the results, it was observed that
addition of 2 % white chicken feather ?bre treated with sodium hydroxide (WFTNa2) gave the best values of 21.03 and
23.58 MPa for tensile and ?exural strength at peak, respectively while WFTNa10 gave the best ?exural modulus value
of 190.50 MPa. The composite samples from the mercerized chicken ?bre displayed the best mechanical properties
