“…The important advantage of reactive pultrusion lies in the low viscosity of thermoplastic resin solution as opposed to thermoplastic polymers, which improves and accelerates impregnation and, in turn, increases production rate. The important factor is the rate of polymerization, as it can take 1 to 60 min for polymerization to complete, depending on the temperature and monomer-to-activator ratio [ 140 , 141 , 142 ].…”

“…Final properties of a material depend both on the quality of manufacturing and on the quality of raw materials. The main problem in thermoplastic composite manufacturing is the need to ensure good impregnation of reinforcing fibers with matrix, as the viscosity of thermoplastic polymers is significantly higher than that of the thermosetting ones, e.g., the average viscosity of thermosetting polymers is 0.03–1 Pa∙s [ 142 ], as opposed to 500–5000 Pa∙s [ 172 ] in case of thermoplastic ones. One way to simplify the process of nonreactive thermoplastic pultrusion is the use of prepregs where reinforcing fibers are in the close contact with matrix uniformly distributed over the whole length of a prepreg.…”

“…Trying to minimize modeling oscillations in the case of high pulling speed and rough mesh, Ruan et al [ 291 ] developed a 2D thermal model of thermoplastic pultrusion. Subsequently, Yn et al [ 142 ] utilized the finite difference method to predict temperature and reaction evolutions within the pultruded profile and to optimize process parameters while maximizing the thickness of pultruded profile. Nejhad [ 148 ] proposed and verified experimentally a numerical model dealing with thermal analysis of impregnated tows/tapes in thermoplastic pultrusion.…”

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.

Most industrial systems are developed and improved more from experimental data than from theoretical analysis. In this work, the robust design and optimal design of products and processes are developed using an information-index-based artificial neural network response surface. The structure and training policy of such an artificial neural network model are determined by the cross-validation information index (CVI for short) developed in this work. In the case of noisy and limited experimental data, this information index is particularly useful for finding the number of nodes in the hidden layer and the weighting of the smoothness factor. The polymer composite pultrusion process is studied. Simulation and experimental results show that this novel approach is highly effective and promising.

Long glass fiber reinforced Nylon 6/Amine Terminated Butadiene Acrylonitrile (ATBN) block copolymer pellets were prepared by a pultrusion process. Optical microscope (OM) and scanning electron microscope (SEM) showed that the fiber dispersion and fiber-matrix bonding in the injection molded long glass fiber reinforced Nylon 6/ATBN block copolymer pellets are better than that from the conventional melt pelletized process. The fiber length distribution in the molded samples was calculated by image analyzer. The static tensile strength, tensile modulus, flexural strength, flexural modulus, notched Izod impact and heat deflection temperature (HDT) of injection molded long glass fiber reinforced Nylon 6/ATBN composites are superior to those of the short fiber reinforced Nylon 6 composites. Moreover, the effect of acrylonitride content on the degradation temperature of injection molded long glass fiber reinforced Nylon 6/ATBN composites was studied.
