Notes:
This paper deals with the characterization of the mechanical properties of Kevlar/nylon composites. It has been shown that addition of up to 5 % Kevlar to nylon matrices (nylon-6, nylon- 11, and nylon-6,6) is possible by melt blending, and results in improved mechanical properties as compared to the pure matrix. In order to increase the interfacial adhesion of the fibers and the matrix, various chemical treatments were performed on the fibers: surface hydrolysis, succinyl chloride reactions and suberoyl chloride reactions. These were shown to affect significantly the mechanical properties, and depending on the treatment Of the fiber, improvement or deterioration of the mechanical properties could be observed. The effect of humidity has also been investigated, and it was shown that the addition of Kevlar greatly reduced the susceptibility of the tensile modulus to humidity.
