“…A nonreactive pultrusion machine for thermoplastic composites consists of towpregs bobbins, guiding system, preheating chamber (preheater), heated forming die, cooling die, puller, and a cutting saw ( Figure 2 ) [ 30 ]. Pretreated fibers, blended intimately with thermoplastics at the filament level at certain ratio, are fed into the guiding system in order to prevent their entanglement and to distribute fibers over the whole section of the profile.…”

“…Among the published articles and books on mathematical modeling in thermoplastic pultrusion, of particular interest is the book by Suresh Advani and Murat Sozer [ 272 ]. Currently, several studies of residual stresses and strain are underway in the field of thermoset pultrusion [ 30 , 171 , 273 , 274 , 275 ], while the number of similar studies for thermoplastic pultrusion is significantly lower. An overview of existing mathematical models of nonreactive thermoplastic pultrusion follows.…”

“…This method allows fabrication of products having constant cross-section [ 24 , 25 ]. The advantages of pultrusion over other composite manufacturing processes are its high production rate of up to 5 m/min [ 1 ], higher efficiency [ 26 , 27 ] and low costs [ 28 , 29 ] of production, and the ability to produce profiles of virtually indefinite length [ 30 ]. There are thermoplastic and thermoset matrix-based composites [ 31 , 32 ].…”

Pultrusion is one of the most efficient methods of producing polymer composite structures with a constant cross-section. Pultruded profiles are widely used in bridge construction, transportation industry, energy sector, and civil and architectural engineering. However, in spite of the many advantages thermoplastic composites have over the thermoset ones, the thermoplastic pultrusion market demonstrates significantly lower production volumes as compared to those of the thermoset one. Examining the thermoplastic pultrusion processes, raw materials, mechanical properties of thermoplastic composites, process simulation techniques, patents, and applications of thermoplastic pultrusion, this overview aims to analyze the existing gap between thermoset and thermoplastic pultrusions in order to promote the development of the latter one. Therefore, observing thermoplastic pultrusion from a new perspective, we intend to identify current shortcomings and issues, and to propose future research and application directions.

Currently, the application of pultruded profiles is increasing owing to their advantages, such as light weight, high strength, improved durability, corrosion resistance, ease of transportation, speed of assembly, and nonmagnetic/nonconductive characteristics. This review analyzes the main application fields of elements produced by pultrusion manufacturing processes: bridges and bridge decks, cooling towers, building elements and complete building systems, marine construction, transportation, and energy systems. Analysis of the scientific literature in relation to the mechanical behavior of pultruded elements is presented as well. Finally, this review outlines the future study possibilities, giving the researchers and practitioners the directions for deeper investigation of specific features and exploration of new ones concerning the mentioned aspects of pultruded fiber-reinforced polymer composites.

The pultrusion process has received increasing attention because of its high productivity, low cost, and good product quality. During the pultrusion process, the pulling and pretension force is a key factor to control the quality of the products. In this paper, the effect of the pretension force on the tensile strength of basalt fiber‐reinforced polymer (BFRP) composites was studied. The pretension force was controlled using different weights. Tensile tests were performed on the BFRP specimens and the microscopic analysis was examined by scanning electron microscopy. The results showed that the static tensile strength of specimens climbed up initially, followed by a decrease with the increase of pretension weights. Three microscopic changes under different pretension forces were found and discussed to explain the damage and failure mechanism. It is essential to optimize the pretension force to improve the strength quality for the pultrusion products of BFRP.
