Abstract:
Carbon fibers (also known as graphite fibers) are high-performance fibers, about five to ten micrometers in diameter, composed mainly of carbon, with high tensile strength. Plus, they are extremely strong with respect to their size. They have high elastic modulus in comparison with glass fiber. According to the working period, carbon fibre-reinforced polymers possess more potential than those with glass fiber. However, they are relatively expensive as compared to similar fibers, such as glass fiber, basalt fiber, or plastic fiber. Its high quality, lightweight, and imperviousness to erosion, m

Phenomenological theories on the effect of pulp fiber properties on the fracture energy of paper are discussed. The effect of fiber length and strength is clarified experimentally. Fiber length appears to affect fiber failure probability only slightly. When fiber strength is changed, the fracture energy decreases greatly with only a small increment in fiber failure probability. This suggests that the fracture energy contribution of a fiber may be correlated between fibers.

Effects of inter-fiber distance and angular orientation on the fiber-matrix interface debonding are investigated using a hybrid experimental-computational approach. Model composite samples are fabricated using two glass macro fibers embedded in a clear epoxy resin and then subjected to remote tensile loads. The distance and angular position between the two fibers in the epoxy are varied systematically to cover a wide range of inter-fiber distances and orientations. Specifically, the model composites are designed to include fiber-to-fiber angles ranging from 0° to 90° in 15° increments. Displac

Abstract:
Objectives. To support a planned update of the Dietary Recommended Intake of macronutrients, including dietary fiber, we conducted a systematic review of the effect of fiber on laxation outcomes (related to gut motility) in people with normal bowel function. Data sources and review methods. We searched PubMed, Embase, and existing systematic reviews to March 4, 2025 for randomized trials in the general population of people in any life stage (without bowel dysfunction) that compared amounts, types, or forms of fiber. Outcomes of interest were stool consistency, fecal weight, fecal frequency, gu

Abstract:
Steel fibers are typically used in ultra-high performance concretes (UHPC) to impart flexural ductility and increase fracture toughness. However, the mechanical properties of the steel fibers are underutilized in UHPC, as evidenced by the fact that most of the steel fibers pull out of a UHPC matrix largely undamaged during tensile or flexural tests. This research aims to improve the bond between steel fibers and a UHPC matrix by using steel wool. The underlying mechanism for fiber-matrix bond improvement is the reinforcement of the matrix tunnel, surrounding the steel fibers, by steel wool. Si

Abstract:
A patented active porcelain enamel coating improves both the bond between the concrete and steel reinforcement as well as its corrosion resistance. A Small Business Innovation Research (SBIR) program to develop a commercial method for production of porcelain-coated fibers was developed in 2015. Market potential of this technology with its steel/concrete bond improvements and corrosion protection suggests that it can compete with other fiber reinforcing systems, with improvements in performance, durability, and cost, especially as compared to smooth fibers incorporated into concrete slabs and b

Abstract:
Corrosion of commonly used steel reinforcements weakens the structural strength of concrete. To address this issue, research was conducted on concrete reinforcements in the form of polymer fibers. These polymer fibers need concrete bonding ability and good mechanical properties. This study investigates core-shell fibers produced from polyketone and polypro pylene mixed with a compatibilizer. The core-shell fibers were produced by coextrusion and drawing. The fibers were analyzed by tensile tests, a single fiber pull-out test, contact angle measurements, scanning electron microscopy, and thermo
