“…A semimanufactured product (uncured preform) of filaments, yarns, tapes, or impregnated fabrics is rolled layer by layer with controlled tension on the chuck or in previous layers. By varying the angle of winding or deposition of the tape, it is possible to control the angle of reinforcement of the fibers in the FRP in each layer [31]. The desired winding angle of the fibers is reached by controlling the displacement speed of the transverse car and the rotation speed of the chuck [32].…”

A wide range of engineering applications adapts Fiber Reinforced Polymer composite due to its unparalleled advantages. Several promising literature reviews are available on the subject of Fiber-reinforced polymer composite. However, there is no study dedicated to the processing/ fabrication of Fiber-reinforced composite. This article mainly includes various types of processing methods (open and close mold) of FRPs and the future scope of the FRPs. Additionally, destructive, and non-destructive evaluation techniques that are used for conventional composites are included as well. Further, the content of this article reviews some fundamental studies on the subject of FRPs, the established concepts, and some existing contradictions related to the fundamental study that is reported by authors previously.

NANOHYBRID POLYURETHANE/FUNCTIONALIZED SILSESQUIOXANE SYSTEMS. Part I. STRUCTURAL INVESTIGATIONS USING FT-IR AND NMR METHODSSummary -A chemical structure of polyurethane/functionalized silsesquioxane (PUR/PHIPOSS) nanohybrid materials obtained by prepolymer method has been determined. In the 1 H NMR and 13 C NMR spectra signals from protons and carbon atoms of the characteristic fragments of the PHIPOSS pendant group have been identified. Analysis of the obtained PUR/PHIPOSS elastomers by ATR-FTIR allowed us to estimate the influence of oligosilsesquioxane side groups on the density of the hydrogen bonds and phase separation. It was found that the degree of phase separation increases with increasing PHIPOSS content.

“…The two materials are typically heterogeneous but can consist of different physical forms of the same material [ 3 ]. In polymer-matrix composites, polymer resin forms the matrix of the composite and also acts as a binder and a stress transfer medium for the reinforcement component, which typically consists of fibres or textile structures [ 1 , 2 , 4 , 5 ]. The matrix can consist of an elastomeric, thermoset or thermoplastic polymer depending on whether a flexible or structural composite is required [ 6 , 7 ].…”

Mechanical Properties of Nonwoven Reinforced Thermoplastic Polyurethane Composites

et al. 2017

Reinforcement of flexible fibre reinforced plastic (FRP) composites with standard textile fibres is a potential low cost solution to less critical loading applications. The mechanical behaviour of FRPs based on mechanically bonded nonwoven preforms composed of either low or high modulus fibres in a thermoplastic polyurethane (TPU) matrix were compared following compression moulding. Nonwoven preform fibre compositions were selected from lyocell, polyethylene terephthalate (PET), polyamide (PA) as well as para-aramid fibres (polyphenylene terephthalamide; PPTA). Reinforcement with standard fibres manifold improved the tensile modulus and strength of the reinforced composites and the relationship between fibre, fabric and composite’s mechanical properties was studied. The linear density of fibres and the punch density, a key process variable used to consolidate the nonwoven preform, were varied to study the influence on resulting FRP mechanical properties. In summary, increasing the strength and degree of consolidation of nonwoven preforms did not translate to an increase in the strength of resulting fibre reinforced TPU-composites. The TPU composite strength was mainly dependent upon constituent fibre stress-strain behaviour and fibre segment orientation distribution.
