Single layer fabrics

The process is initially quite rapid, however, the rate decreases as the thickness of the infiltrated layer increases. The use of EPD allows for reasonable infiltration within the fabric tow. Single layer fabric mats have been infiltrated with this process and then taken... 

Fire scientists tend to classify materials as being either thermally thick or thermally thin. By thermally thin means that heat absorbed on one surface of the material will penetrate its thickness sufficiently rapidly, so that there will be no significant temperature gradient through the material depth.i Textiles in the form of single-layered fabric assemblies are usually dimensionally thin and hence could be classed as thermally thin materials. 

Although single-layer fabrics are used as filters - cheesecloth is a notable example -adding additional layers often improves performance. Figure 1.14(a) shows a multilayer woven filter fabric firom the Chinese company, Zhejiang Suita Filter Material Technology Co., Ltd. Figure 1.14(b) shows Dynapore, a 3D woven filter fabric made of metal wires by Martin Kurz and Company. 

Consider the combination of weave of two single-layer fabrics. Let Mi and M2 be the matrices for two single-layer fabric sections. To unify the repeat size of the two layers, the lowest common multiple (1cm) is calculated based on the dimensions of these two matrices. Assume that di is the dimension of Mi and d2 that of M2. If cm di,d2) is equal to d (or d2), the dimension of M2 (or Mi) will be expanded to be of the same size of di (or d ). If cm di,d2) is larger than both di and c 2, then Ml and M2 will have to be expanded to the new dimension lcm(di, c/2) Let the enlarged matrix be ME. The elements of this matrix are assigned as follows ... 

Area 1 includes three layers of fabrics, which have different lengths and possibly different weaves. All layers in this area are single-layer fabrics. The length ratio of these three fabric layers in area 1 is defined as I1.I2.I1-... 

Area 2 includes two sections of fabrics, each having the same lengths and possibly different weaves. However, the top fabric section is a combined layer made from top and middle fabric layers from area 1, and the bottom section is a single-layer fabric, the same as layer 111 in area 1. The weave for area 3 is the same as that for area 1, and area 4 is similar to area 2 except that the top section is a single layer and the bottom section is a stitched layer in this case.

The manufacturing process for multilayer microfluidic soft electronic devices resembles the single-layer fabrication, but with a few minor modifications and additional process steps, cf. Figure 18.19.
