Study on the Internal Permeable Property of Thick-Section Reinforcement During LCM Process
摘要
Abstract
An on-line sensor and monitoring system was used to study the internal permeable property of thick-section preforms during liquid composites molding(LCM) process.It was noticed that the permeability is decreasing when the thickness of reinforcements is increasing.The slope of the decreasing is getting smaller with the increasing number of layers.By comparing flow front position of the top and bottom layer of the reinforcements,it was found that the lead-leg between the top and bottom layer is increasing when the thickness of reinforcement increases.The combination of distribution media and strand mat can be used to increase the impregnation when the structure design allows.关键词
