Properties and Process Ability of Long Fiber-Reinforced Polymeric Composites

摘要

The addition of nanoparticles to polymeric matrices has shown great promise for improving mechanical and thermal properties; however, this improvement comes with a decrease of processability. In this study, two different glass fabrics were used. One of them was Windstrand, a stitched equally-biaxial R-glass fabric the other was Advantex, a unidirectional glass fiber mat. Both of them are provided by Owens Corning. The mats were sprayed with carbon nanofibers (CNF) on both sides. Mechanical properties of composites manufactured via vacuum-assisted resin transfer molding were obtained. Permeability, as a measure of processability, of the sprayed glass mats was measured. Mechanical properties are improved, whereas permeability decreases with the addition of CNF.
