Hey Guys,

I am just working on a project at my college to fabricate a monocoque car chassis from carbon fiber and fiber glass by the resin infusion method, there's something that i would like to want regarding the curing temperature.

Almost all of the articles and videos on the internet states that we have to leave the parts after being infused to cure under the normal room temperature for 24 hours, while some people has recommended to me to raise the temperature around the parts during the curing process to around 110 C. Because this will make the parts stiffer and stronger. 

Please guys i want to hear what is better ? since that i want the part to bear stresses and support loads.

Thanks,

You are correct, most infusion resins are capable, and perfectly fine with a room temperature cure. However, an elevated temperature post cure can have benefits in mechanical performance as well as the more obvious HDT. Rather than saying to cure at 110C, I would recommend you check for the correct post cure procedure for the resin system you are using.
