AN ANALYSIS ON THE TENSILE STRENGTH OF HYBRIDIZED REINFORCEMENT FILAMENT YARNS BY COMMINGLING PROCESS

초록

Carbon, aramid and glass fibers are inherently superior to conventional textile fibres in terms of mechanical properties as well as other chemical characteristics. Because of the inherent advantages and disadvantages associated with each material, it is better to hybridize them to fully benefit of their high performance in many practical applications. The fibers produced in this process show the possibility of light weight composites as end products. Today, these fibers are mostly used in high performance applications such as aerospace industry, geo-textile, auto industry etc. Among the processes producing hybridized filament yarns, the commingling process, in which reinforcement filament yarns are well mixed together with the medium of matrix material such as polyether-ether-keeton or polyester or polypropylene filaments in one air stream. The commingling processes have been reported to achieve evenly distributed filaments over hybrid yarn cross section [1].
