Effect of Bleed Schedule on the Mechanical Properties of Carbon Fibre Reinforced Epoxy Laminates

Anne-Marie Lane

Abstract


This research project aims to identify the impact that the use of different bleed schedules while vacuum bagging during the manufacture of an advanced composite has on the mechanical properties achieved by the end product. This is done by conducting tension, compression and flexural testing on five carbon fibre reinforced epoxy laminate specimens that were manufactured using different bleed schedules. It is found that there exists a trend between the bleed schedule used and both the tension and flexure properties achieved. This is due to the impact that the amount of resin bleed has on the thickness and the fibre-volume ratio of the composite product. As such, it is suggested that this report supports the importance of considering the resin bleed schedule used during the manufacture of an advanced composite material.
