Castor Oil-Based Polyurethane/S2 Glass/Aramid Hybrid Composites Manufactured by Vacuum Infusion

Abstract: This study evaluates the hybridization effect of S2-glass/aramid on polyurethane (PU) composites produced by vacuum infusion. Different laminates were produced with similar thickness (around 2.5 mm), using, as reinforcement, only aramid fabrics (five layers, named as K5) or only S2-glass fabrics (eight layers, named as G8). Furthermore, hybridization was obtained by manufacturing symmetrical hybrid inter-ply laminates, with four S2-glass layers and two of aramid, (G2K)S and (KG2)S. The mechanical response of t… Show more

“…In particular, when rheological percolation is reached, viscosity of the resin changes to a certain point that the curing is affected. Thus, in highly demanding applications or in composite manufacturing processes where resin viscosity is crucial, e.g., RTM and vacuum infusion, it is necessary to understand the influence that these particles have on the curing process since the final properties of the composite significantly depends on the initial conditions of the resin 5–7 …”

[5][6][7] A poor chemical interaction is a significant obstacle to the effective dispersion of carbonaceous nanoparticles such as GN and CNT in liquids and resins. This is related to the van der Waals forces, that promote their agglomeration, and the polar groups in their structure, that enable hydrogen bonds and yield stable suspensions.…”
