3D spacers enhance flow kinetics in resin transfer molding with woven fabrics

Véronique Michaud, Baris Çaglar, Damiano Salvatori

Impregnation time in Resin Transfer Molding (RTM) is directly proportional to resin viscosity and inversely proportional to fabric permeability, limiting the use of high-viscosity resins with conventional reinforcements. In this study, we show how to reduc ...

Light diffusion in GFRP laminates for building construction

Thomas Keller, Andreas Schueler, Julia De Castro San Roman Fest, André Gabriel Kostro, Carlos Pascual Agullo

The light diffusion of hand lay-up glass fiber-reinforced polymer (GFRP) laminates was investigated with a spectrophotometric set-up using an integrating sphere. Reinforcement weights of the laminates ranged from 410 to 3280 g/m2 and fiber volume fractions ...
