Abstract
End-of-life recycled polyvinyl chloride (rPVC) particulates were used as a filler to improve the mechanical performance of polyurethane (PU) based fiber reinforced polymer sandwich composites. rPVC particles were added from 2.5 wt% till 20 wt% in PU foam. Optical microscopy images revealed the variation of cell size of PU foam with respect to rPVC inclusion, i.e., progressive addition of rPVC particles decreased the cell size of PU foam. Using various density calculations, it was found that the added rPVC particles resulted in the opening of cellular structure of PU foams. Facesheet - core combination sandwiched composite specimens was fabricated using a woven fabric basalt fiber reinforced polymer (BFRP) face sheet with rPVC reinforced PU foam as core. A bicomponent epoxy resin was used as a matrix in the facesheet composite. The tensile and composite strengths were assessed through the flatwise tensile and compressive tests to evaluate the effect of PVC particles in the core of the s...I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
