TEXCOMP for MS-Excel(R) is a three-dimensional geometric and elastic analysis program for woven fabric composites. Not only basic weave styles such as plain, twill, and satin, but also self-designed weave styles can be treated by the model. For this, a library of 108 macro-cells has been created to construct each possible type of unit cell. Dialog boxes and command buttons are used to navigate through the custom application. Of course, all the standard MS-Excel(R) capabilities are available. In addition, the program adds customized on-line help. With TEXCOMP, an efficient and accurate stiffness analysis on PC is now available for a large range of woven fabric composites.
