“…Moreover, a constant cross section is a limitation of this process [13]. But the fibers in pultruded material are generally well aligned [14]; it helps to reduce fiber misalignment in the composite through optimization of manufacturing process variables, such as pull-speed, preformer temperature, nanoparticle alignment and/or dispersion. The RTM is a closed mold operation [13].…”

“…Hussain et al [17] achieved an almost (by dispersing only 1% by weight nanosilicates) 18 and 24% improvement in flexural strength and fracture toughness respectively in S2 glass/ vinylester-clay nanocomposites compared to conventional composites [17]. Roy and Hussain [14,102] manufactured E-glass/PP clay nanocomposites using prepreg tapes with extruder and pultrusion machine. They achieved improvements in compressive strength and modulus using this technique.…”

Numerical calculations were performed to examine the mechanisms for generation of a retro-reflected wave from the interaction of an evanescent wave with a sub-wavelength structure using the finitedifference time-domain (FDTD) method. The simulation shows that an evanescent wave is reflected from the structure at the interface between a high index dielectric material and a low index material. The reflected evanescent wave couples into the upper medium and radiates its energy forming a retro-reflected wave, which appears as a sharp peak near the edge of the structure when imaging the structure in hyper-numerical-aperture solid immersion microscopy. We propose a simple theory and verify it through FDTD calculation under various circumstances in order to explain peculiar features of this phenomenon. Furthermore, we suggest a way to control the reflection of the evanescent wave by taking advantage of the interference of the evanescent wave inside the structure.

“…The fibers in pultruded materials are generally well aligned, 78 which helps to reduce fiber misalignment in the composite by optimizing the manufacturing process variables, such as pull-speed, preformer temperature, nanoparticle alignment, and/or dispersion. Hussain et al 79 studied the compressive strength of pultruded thermoplastic composites containing 5 and 10 wt% nanoclay reinforcement and observed consistent improvements in the compressive strength and modulus up to about 122% at 10% clay loading.…”

As the utilization of advanced composites in structural applications grows, the need for improving their through-thickness properties becomes imperative. Although the behavior of composite laminates under structural and thermal loads has received much attention with their growth in safety critical structures, more effort needs to go into selectively improving their electrical and thermal conductivities. Additionally, the ability to manufacture composite structures that can inherently monitor their own health will be exceedingly beneficial. This paper provides an overview of advances made towards multiscale composite manufacturing. Multiscale composites, especially with the use of carbon nanotubes, have been sought to provide enhanced structural (through-thickness) properties and increased electrical and thermal conductivities. This report will review the state of art in the manufacturing of multiscale composites, their scalability, and their inherent potential for multifunctionality. Current techniques mostly result in the application of carbon nanotubes throughout the entire laminates, rather than in selected areas. Subsequently, one of the main barriers, to the widespread use of carbon nanotube-applied composites, is an efficient mass-producible manufacturing process. This paper attempts to highlight the current knowledge gaps in this critical area of composites manufacturing.

“…Simultaneously, Broyles et al [ 175 , 176 , 177 ] studied the influence of fiber sizing agents on the mechanical properties and moisture absorption. Next, Roy et al [ 178 , 179 ] succeeded in improving compression behavior of pultruded composites by modifying material composition and parameters of the thermoplastic pultrusion process. Subsequently, Fink and Ganster [ 180 ] conducted an experimental study of the influence of synthetic fibers and of the choice of matrix on mechanical properties of composites.…”

Thermoplastic Pultrusion: A Review

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.
