“…The results suggest that incorporating FA as filler does not impact the Tg of the PVC foam composites significantly. This behavior is similar to the results observed in PVC/cumbaru filler and PVC/Carbon fiber composite systems reported by Iulianell et al [30] and Ráthy et al [31], respectively.…”

Fly ash particles are usually spherical and based on their chemical composition; they are categorized into two classes: C and F. This study compares the microstructural, mechanical and thermal properties of extruded rigid PVC foam composites reinforced with class C and class F fly ash. The mechanical properties: such as tensile and flexural strength of composites containing class C fly ash were superior to the composites containing class F fly ash particles. Composites containing 6 phr class C fly ash showed a 24% improvement in the tensile strength in comparison to a mere 0.5% increase in composites reinforced with class F fly ash. Similarly, the addition of 6 phr of class F fly ash to the PVC foam matrix resulted in a 5.74% decrease in the flexural strength, while incorporating the same amount of class C fly ash led to a 95% increase in flexural strength. The impact strength of the composites decreased as the amount of either type of fly ash increased in the composites indicating that fly ash particles improve the rigidity of the PVC foam composites. No significant changes were observed in the thermal properties of the composites containing either type of fly ash particles. However, the thermo-mechanical properties measured by DMA indicated a steep increase in the viscoelastic properties of composites reinforced with class C flyash. The microstructural properties studied by Scanning Electron Microscopy (SEM) confirmed that fly ash particles were mechanically interlocked in the PVC matrix with good interfacial interaction with the matrix. However, particle agglomeration and debonding was observed in composites reinforced with higher amounts of fly ash.

“…Certain applications of PVC foam products require excellent dimensional stability, such as in exterior mouldings, siding, decking and railing applications. Solid fillers, such as calcium carbonate, talc, glass fibers, carbon fibers, and wood fibers have been reported as effective PVC reinforcement additives in many publications [3][4][5] . The selection process for an effective reinforcement filler depends on its compatibility with the polymer matrix and the desired relationship between structure, property, and performance of the composite.…”

In this work, short E-glass fibers (GF) and Mica were used to enhance the dimensional stability and mechanical properties of extruded rigid Polyvinyl Chloride (PVC) foams.Experimental results show that the dimensional stability increased by 50% and heat resistance of the PVC foam improved as the amount of reinforcing solids increased in the composites. The storage modulus, tensile, and flexural strengths of the composites improved by 220%, 82%, and 46%; respectively. SEM micrographs show good interaction between glass fibers and foam cells and a good dispersion and orientation of the mica flakes along the cell walls of the PVC foam.

“…[10][11][12][13] Fillers such as mica, calcium carbonate, talc, glass fibers, carbon fibers, and wood fibers have been used to improve the properties of PVC composites. [14][15][16] Mica is a flaky-like crystalline alumino-silicate with a high aspect ratio. It has excellent chemical and corrosion resistance, good electric properties, and low thermal expansion, and it causes low wear and abrasion to the processing equipment.…”

In this study, the effect of reinforcements' shape and type on the mechanical, thermal, and morphological properties of polyvinyl chloride (PVC) foam composites is investigated. For this purpose, three different fillers, longitudinal structure glass fiber, flaky structure mica, and spherical structure fly ash, were selected to prepare PVC foam composites with 0-20 wt% loading. The tensile strength in both 10 wt% reinforced mica and glass fiber composites improved slightly, while it decreased with the addition of 10 wt% fly ash. Flexural strength reached its maximum in mica and fly ash-filled composites at 10 wt% loading. Meanwhile, flexural strength exhibited higher saturation levels of longitudinal glass fibers due to their penetration within the foam cells. Charpy impact strength measurements showed a decreasing trend with increasing the filler content; however, the rate of reduction was the lowest in PVC/glass fiber foam composites. The effect of filler type and geometry on thermal and dynamic mechanical properties of PVC foam composites was studied using thermogravimetric analyzer and dynamic mechanical analysis, respectively. First decomposition temperature of PVC composites dropped slightly with the addition of fillers, where glass fiber-reinforced foam composites exhibited the lowest rate of reduction. The second decomposition step of PVC foam composites shifted toward higher temperatures with increasing the filler content. Fly ash was found to be more effective in improving the second decomposition temperature. The dynamic modulus of mica and glass fiber-reinforced composites showed an increasing trend below and above glass transition temperature, up to 10 wt% loading, while the storage modulus in fly ash-reinforced composites increased with increasing the filler content at a constant rate. Morphological studies revealed that mica flakes with a paralleled structure within cell walls and glass fibers Downloaded from with a penetrated structure within the cell bubbles exhibited higher agglomeration compared to fly ash composites.
