Research of the Influence of Starch-Based Sizing Agent on the Stiffness of Glass Fibre
Abstract:
The stiffness of pristine glass fibre and glass fibre coated with starch sizing agent were studied on different storage conditions. The results indicate that the glass fibre coated with starch sizing agent is greatly influenced by the environment. It was confirmed that the starch sizing agent is the main factor affecting the stiffness of glass fibre. Using SEM, FTIR, XRD, DSC, three kinds of starch sizing agents under different storage conditions were studied. The results show that dried starch films produce holes that absorb water in humidity environment. Some bound water formed during the moisture absorbing process. The molecular structure, ordered degree and heat resistance of deteriorated starch is affected by the wet storage conditions.
