The purpose of these studies is to add value to the animal fibers and consequently to improve the properties of poly(lactic acid) (PLA)/silk fiber (SF) green composites for the potential use in environmental engineering applications such as food packaging and medicines. PLA/SF biocomposites were prepared by internal melt mixer and compression molding machine. Surface treatment of fiber was investigated in order to improve interfacial adhesion of SF reinforced PLA composites. Fiber was treated with sodium hydroxide (NaOH) 5% w/v for 1 h. The effect of fiber content and length on the mechanical and thermal properties of PLA matrix were studied. Experimentally, it was found that the weight content and fiber length of fillers are key parameters that substantially influence the tensile modulus and impact strength of the composite samples. The surface of the fibers was well bonded with the matrix, as observed by a scanning electron microscope (SEM) image of fractured sample. The thermal stability and crystallinity (Xc) of PLA/SF composites increased with increasing fiber content..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
