The through-thickness compressive behavior of fabric reinforcements is crucial in liquid composite molding manufacturing processes. Predictive simulations the response are thus necessary to enable a virtual processing workflow. These complex however, as reinforcement fabrics non-linear. Altough fiber modeling has proven be strong kinematical tool, it cannot predict due lack bending stiffness fi...

A novel numerical approach to analyze the mechanical behavior within composite materials including inelastic regime up final failure is presented. Therefore, a second-gradient theory combined with phase-field methods fracture. In particular, we assume that polymeric matrix material undergoes ductile fracture, whereas continuously embedded fibers undergo brittle fracture as it typical e.g. for r...

Smart textiles promise to have a significant impact on future wearable devices. Among the different approaches to combine electronic functionality and fabrics, the fabrication of active fibers results in the most unobtrusive integration and optimal compatibility between electronics and textile manufacturing equipment. The fabrication of electronic devices, in particular transistors on heavily c...

The study of natural fiber reinforcement composite structures has focused the attention of the automobile industry due to the new regulation in relation to the recyclability and the reusability of the materials preserving and/or improving the mechanical characteristics. The influence of different parameters on the material behavior of natural fiber reinforced plastic structures has been investi...

Asbestos is a generic term for a group of six naturally-occurring, fibrous silicate minerals that have been widely used in commercial products. These minerals are more commonly found in nonfibrous forms that are not asbestos. Asbestos minerals fall into two groups or classes, serpentine asbestos and amphibole asbestos. Chrysotile, a serpentine asbestos, possesses relatively long and flexible cr...

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.

Abstract Wool fibers have been used as textile raw materials for clothing and home textiles many years. Recently, it has also increasingly in technical applications. However, man-made dominate the market minimize importance of wool industry. On other hand, great future opportunity is growing interest consumers natural, renewable sustainable materials. In addition, past few decades, production i...

Materials Research Group (CMRG) at the University of Mississippi (UM) have recently begun a research study supported by the U. S. Department of Agriculture (NRICSREES-USDA Award number 2003-35504-13627) examining natural fiber reinforcements (NFR). The objectives of this research are to demonstrate the feasibility of using the cost-effective pultrusion process to manufacture high quality polyme...

A solution blow spinning technique was developed using elements of both electrospinning and melt blowing technologies as an alternative method for making non-woven webs of microand nanofibers with diameters comparable with those made by the electrospinning process with the advantage of having a fiber production rate (measured by the polymer injection rate) several times higher. The diameters of...
