Abstract
A method of making a composite laminate includes dequilling chicken feathers to form chicken feather fibers (CFFs). The CFFs and Ceiba Pentandra bark fibers (CPFs) are milled to form milled CFFs and milled CPFs so that the milled CFFs have a length of smaller than 200 microns and the milled CPFs have a length of smaller than 600 microns. The CFFs are treated with an amine compatibilizer to esterify carboxy groups present on keratin in the CFFs. A mixture of an epoxy resin, the milled CFFs, and the milled CPFs is solution cast to form an epoxy composite. A first carbon fabric layer and a second carbon fabric layer are placed on a front side and a backside, respectively, of the epoxy composite to form an epoxy laminate precursor. The epoxy laminate precursor is compression molded to cure the epoxy laminate precursor to form the composite laminate.
