As said above, temperature is key.  It is always better to actually measure the temperature rather than estimate. That way you KNOW you are using a suitable resin system.  You do not want your parts to go soft and get ruined.

I sometimes worry what I'm sending when I use google!

For all the work they put into it, Google Translate still just doesn't work that well



Ok, well you said for a 'car engine'. Basically you are restricted by the heat capabilities of your resin system. You can get quite high temperature epoxies especially if you are using pre-preg, though I gather that you are not. I also don't know where you are based, so I can't say what resin systems are available to you. Where I am, the highest temperature resin I can get without requiring a mortgage or the sale of my mortal soul is 96 degrees Celcius. Which when talking about car engines, is not very high at all. 

Dear ，this is why I want to ask .......

What is it you're trying to make?

I want to buy  carbon fiber plate used for the car engine .But is only the car shell used carbon fiber ,any other parts also used carbon fiber ?HOW?
Your early reply will be highly appreciated .
