Honda CRX carbon air intake

Homemade carbon fiber Honda CRX air intake

This entry is part 32 of 41 in the series TrackDays EF7 HONDA CRX

A carbon fiber intake for the CRX

With the mould finished and prepared, it’s time to think about producing the first carbon part. Before starting the intake itself, I need to apply a “release” agent on the mould and yes, I must say this with the right word : this is so fuc**** long !! You need to apply the wax in thin layers … apply one, wait, polish … apply, wait, polish … and so on a few more times :(.

This is really important as if you skip this step or go too fast, you will destroy your mould when removing the finished part.

The intake itself is made using 4 real layers of real carbon fiber (200 grs per square meters) and low speed drying epoxy resin. The part receives 2 more layers in some reinforced areas. The finished part is so light !

Mould opened with raw part outside.

Inside view. It seems that there is blurr and embossed layers of carbon when in the reality the inside is close to perfectly flat. This rendering is due to the camera flash and close-up.

And a fully finished real carbon intake chamber for the CRX. Even if I’m a ‘light is right’ addict I just decided to go on a ‘luxury option’ to finish the part : a light fine sanding and a thin coat of spray varnish. What a bad guy I am ^^ !!!

    1. You start by applying layers of carbon and epoxy resin on each “half moulds” separately. Then you wait for the resin to start drying, not completely, until you can touch it without having some staying on your finger. Then you prepare the two halfs for assembly.

      You remove the excess of material on the two joigning lines and assembles the mould. When done, the two half parts are just in contact on a small line and this is not strong enough.

      So you apply carbon fiber bands inside the part, over the joigning lines, with resin. Because everything is done before the resin is cured, you finish with a very strong part as strong as it if was made in one piece from the start.

      This is easy on such a design, but becomes more complicated to do on some very complex parts.
