Experimental Research on Prepreg Tack between Layers Based on High-velocity Automated Placement Process
摘要
Abstract
To solve the problem of bonding suitability between adjacent prepreg layers in the automated placement process,a new test system for characterization of prepreg tack which simulates the automated placement process was designed. The test method called two-step method consisting of the automated placement and peeling test has been developed. To study the processing property of CCF300/BA9916-2 epoxy prepreg tack,single factor experiments were carried out to find the influence of the lay-up processing parameters on the prepreg tack. And orthogonal experiments were accomplished to confirm the impact of the lay-up processing parameters. The results showed that the prepreg tack increases along with the increase of lay-up pressure and lay-up temperature,and decreases with the increase of lay-up velocity. The impact of lay-up temperature on prepreg tack is most significant,followed by the impact of lay-up pressure,and the lay-up velocity has the minimum impact.关键词
