Preparation and Performance of CGFS Reinforced PVA/RSP Composite

Abstract:

Application of chopped glass fiber strand (CGFS) in rice straw based composite was studied and the reinforcing effect of CGFS was evaluated. Rice straw powder (RSP) was used as main material and poly (vinyl alcohol) (PVA) was selected as adhesive agent. Composites were prepared by hot-pressing method at 10 MPa pressure, 140 °C for 10 min, with the mass ratio of RSP to PVA of 4:3. Results showed that the tensile strength of the composites first increased and then decreased with increasing CGFS amount. When the mass ratio of CGFS to RSP was 7:15, the composite reached its maximum strength of 20.47 MPa. CGFS showed obvious reinforcing effect. Strength at tensile break showed similar change law and tensile strength equaled to or was slightly higher than the strength at tensile break. The tensile elongations of all composites with CGFS were higher than 20%, proving the toughening role of CGFS. The hardness of composites showed certain non-uniformity and lay between 87 and 96. Negligible difference existed in every composite.
