The objective of this study is to find significant differences in impact forces between continuous, discontinuous, and woven fiber type polyester composites with natural palm fibers out the description microfracture structure. This used experimental methods independent dependent variables. variables are type. Then, variable was forces. Based on results tests, show that from average score at con...

Investigations of the parameters reinforcing structure in form a woven fabric polymer composite material were carried out by numerical technologies order to determine geometric and elastic-viscous elementary periodic cell filler, which is regularly repeated its architecture. The results obtained used development computer system for designing calculating functional unit composite. created images...

This paper deals with the development of a numerical simulation methodology for estimating damages in laminate composite materials caused by a low-speed impact. Experimental tests were performed on laminate plates reinforced with woven carbon fibers and epoxy resin. Three thickness plates were evaluated. The impact loads were transversal and punctual. Two lamina failure criteria were evaluated....

adhesive bonding technology is being used in a variety of modern industries, including the automotive, aerospace, maritime, construction, defense and so on. on the other side, polymeric nano - composites attracted both academic and industrial interests in the past decades. the scope of this paper is experimental investigation on the effects of the addition of alpha-alumina nanoparticles to the ...

A new code construction namely woven turbo codes, is presented , which is a variation of woven convolutional codes. Parallel encoders (turbo codes 2]) can be considered as a special case of woven turbo encoders, where only one outer and inner encoder is used. However, woven turbo codes with a larger number of outer codes yield higher minimum distances than turbo codes with random permutations.

In woven designs from colored threads, a colored pattern is a consequence of two possible arrangements where warp is over the weft or vice versa. Thus the primary elements of woven fabric design are combination of weaves and blending of colors using such weaves. Weave is the scheme or plan of interlacing the warp and weft yarns that produce the integrated fabric. Weave relates specially to the ...
