Polyacrylonitrile (PAN) textile fibers, in the form of fabrics or threads, were compacted in a heat-pressure cycle and crosslinked by nitrile polymerization to form a thermoset composite article, whose mechanical properties were found to surpass thos

In this paper we present a new approach to the problem of textile surface quality evaluation. The approach is based on the capture and analysis of the profile of protrusions. The specific methods of image processing for protrusion detection and param

We describe a new single polymer composite (SPC) prepared from two liquid crystalline vectran fibers. Vectran M is the as-spun fiber while vectran HS is the high-strength version. A study of the morphology of the pristine materials shows that the two

Composites of chopped carbon fibers (CCF) or carbon nanotubes (CNT) with nylon 66 were prepared by melt‐mixing followed by extrusion/drawing of filaments. The combined effect of composition and flow on morphology and crystalline orientation was stu

One of the most interesting questions in the field of polymer composites concerns the microstructure of the transcrystalline (tc) layer which is developed in the polymer film around the reinforcing fibers. In the present study, a single aramid fiber

This paper presents a study of the fatigue behavior, mechanical properties and relaxation processes of UHMWPE fiber compacts as a function of structural parameters and crosslinking. UHMWPE compacts with optional crosslinking are produced by compressi

The temperature dependence of the structure of either cross-linked or non-cross-linked ultra-high-molecular-weight polyethylene (UHMWPE) fiber compacts was studied by synchrotron microbeam wide-angle X-ray scattering (WAXS), focusing on the fiber-fib

Novel peroxide-crosslinked composite materials based on ultra high molecular weight polyethylene fibers were studied in comparison with their non-crosslinked homologues. Two material types were prepared, either by embedding the fibers in a low-densit
