STUDY ON LAMINATING PROCESS OF CONTINUOUS FIBER REINFORCED POLYPROPYLENE PREPARED BY HYBRID YARN FABRIC
摘要
Abstract
In this paper,two different forms of hybrid yarn fabric were used as raw material to prepare the continuous glass fiber (GF) reinforced polypropylene (PP) laminated composites by the laminating process.To prepare the laminate with excellent mechanical property,the influences of molding temperature,molding pressure,molding time and the form of fabrics on the flexural property and interlaminar shear strength (ILSS) of the laminated composites were investigated to get the optimal process parameters.The results show that the laminated composites with optimal mechanical property were prepared at hot pressing temperature of 230 ℃,hot pressing pressure of 8.5 MPa,molding time of 30 min and cooling rate of 0.5 ℃/min.The optimal mechanical properties of the laminate are as follows:flexural strength reaches 352.58 MPa,flexural modulus reaches 23.09 GPa,ILSS reaches 27.37 MPa.At this time,the fiber content and the porosity content of the laminate is 72.25％ and 2.03％,respectively.The flexural strength and flexural modulus and ILSS of laminated composites prepared by two different forms fabric under the optimal processing conditions:2/2 twill fabric＞plain fabric.In addition,the porosity content of the two different laminates prepared by two different forms fabric:2/2 twill fabric＜plain fabric.关键词
