干纤维自动铺放定型剂与铺放工艺研究
Study on Automated Placement Setting Agent and Placement Process of Dry Fiber
摘要
Abstract
During the automated placement process of dry fibers,the positioning and fixation of dry fiber gauze belts are achieved by spraying setting agents.The amount of the setting agent is difficult to control when it is sprayed manually.Furthermore,it can also affect the permeability of the preform,resin injection and the quality of the vacuum assisted resin infusion(VARI)molding,resulting in a decrease in the mechanical properties of composite materials.This study utilizes dry fiber automated placement equipment and an automated spraying system to manufacture preform structures,followed by VARI process to prepare composite samples with varying setting agent contents.Subsequently,mechanical characterization including interlaminar shear,bending and tensile testing is conducted to investigate the influence of setting agent content on both the manufacturing process and the mechanical properties of composite products.The results show that the interlaminar shear strength,bending strength and tensile strength of the sample gradually decrease with the increase of the content of the setting agent.The optimal setting agent content for automated laying of dry fiber is determined to be 4%—6%,balancing the preformed body's layup quality and its impact on mechanical properties.Compared with agent-free samples,this range results in reductions of 3%in interlaminar shear strength,9%in bending strength,11%in bending modulus,and 13%—16%in tensile strength.关键词
