Step 1


Following automated ply cutting, plies three through six of the hood outer panel are consolidated under vacuum on a male-form preform tool. Source: MacLean Quality Composites

Step 2


After application of mold release, the first two plies of prepreg are layed into the mold by hand, followed by the remaining four-ply preform. Source: MacLean Quality Composites

Step 3


A formed silicone vacuum bag is used to evacuate the air. The reusable bag saves time and results in a smoother part surface than a disposable bagging. Source: MacLean Quality Composites

Step 4


The prepreg is cured in an autoclave at 100 psi and 150C/302F. The cycle time in the autoclave is approximately two hours, including heating, cure and cooling. Source: MacLean Quality Composites

Step 5


Following cure, the carbon fiber hood outer panels are demolded and the edges trimmed on a 5-axis CNC router. Source: MacLean Quality Composites

Step 6


The inner and outer panels are bonded together in a vacuum fixture using a room-temperature, two-part polyurethane structural adhesive. Source: MacLean Quality Composites

Step 7


The bonded hood assembly shows the compression molded inner panel, supplied by Meridian Automotive Systems. Low-density SMC (light gray) is co-molded with carbon fiber SMC (perimeter of inner panel). Source: MacLean Quality Composites

Step 8


The assembled hood is inspected for dimensions, and then for surface quality in a specially designed light room. If required, surface defects are repaired prior to application of primer. Source: MacLean Quality Composites
