“…Although, a divergent view was observed in a thermoplastic epoxies composite by (Devaux and Caze 2000), with a tendency of exhibiting various types of morphology, resulting into complex backbone structure, and different molecular weight which complicates the analysis of such composite. The behavior of an epoxy matrix composites with unsaturated polyester and polyurethane matrix have been studied by (Rahman et al 2013). They found that these specimens displayed good interfacial adhesion between the fiber and the resin resulting in better mechanical properties.…”

Abstract:In this paper, attempts were made to study the progression of fibre-matrix adhesion of five composite specimens taking into consideration the hand lay-up method of composite formation. The ampreg 21 epoxy resin was used as the matrix for the glass fibre-epoxy resin formation. E-Glass fibre was used as matrix reinforcement. The morphology and the XRD of these composites were examined. Key of the findings from the morphological analysis of these composites showed that the fractured surface of the samples depicted better adhesion between the matrix and the fibres. The micrographs and EDS of the composite specimens also showed the retention of elemental composition of the glass fibre which is in line with other published works. The XRD results of these composites indicated a peak at Bragg's angle 2θ=20.6 o , affirming the remnant crystalline silica in the composite. Hence, these composites are projected to possess better dimensional stability adaptable for high performance structural applications.

“…At high frequencies, the molecular chains do not have sufficient time to reorient before the next deformation cycle; therefore, a higher temperature, and more energy, is required to initiate this reorientation. It has been reported that the inclusion of reinforcing fibers to a polymeric matrix can both increase or decrease the glass transition temperature in the material depending on the fiber type, and the strength of the fiber matrix bond . Another consideration is the relative molecular weight of the matrix materials in question.…”

Influence of glass fibers and rubber particles on the viscoelastic behavior of polyamide 6,6 blended composites

2019

Recently, in many industrial fields, there has been a drive to replace traditional metallic components with high strength polymer composites in the interest of reducing weight. Polyamide 6,6 (PA66) is a high strength thermoplastic and the behavior can be further enhanced by the addition of reinforcing fillers. Here, PA66 matrix has been reinforced with chopped glass fiber as well as hybrid composites containing both glass fiber and rubber particles. First, a baseline characterization of the mechanical properties is presented followed by a report on the thermal transitions, melting, crystallization, and glass transition, for the composite and pure materials. It is found that the filled samples show lower degree of crystallization and that the glass filled samples show lower crystallization and melting temperatures. Additionally, it was found that the glass reinforced samples led to a decrease in the glass transition temperature (Tg) while higher testing frequencies corresponded to an increase in Tg. Finally, it was demonstrated that the glass filled compounds were able to better retain their mechanical properties at high temperatures relative to the unreinforced materials. POLYM.

Effect of maleic anhydride‐grafted polypropylene on the flow orientation of short glass fiber in molten polypropylene and on tensile properties of composites

et al. 2017

Composites of polypropylene (PP) and PP blended with maleic anhydride-grafted polypropylene (MAPP) reinforced with short glass fibers were prepared via extrusion compounding and injection molding techniques. The fiber length did not significantly change irrespective of the presence of MAPP after compounding and injection molding. However, the tensile strength of PP/fiber showed significant improvement after MAPP addition. The interfacial shear strength between PP and fiber increased with the addition of MAPP. Examination of the failure surface of a dumbbell specimen after tensile testing confirmed that the fiber highly orientated in the flow direction in the PP/MAPP matrix. The tensile strength enhancement was attributed to the improvement of the interfacial shear strength between PP and fiber. Moreover, in the injection molding process, there was high orientation of the fiber in the flow direction when there was MAPP. We concluded that the presence of MAPP causes increased orientation of the fiber.
