Why Do Carbon Fiber Spoilers Fade?
How UV Rays Affect Carbon Fiber
UV rays are harmful to your carbon fiber spoiler. Sunlight breaks down the protective resin layer on top. This process, called photo-oxidation, causes fading and weakens the material. Over time, the shiny surface becomes dull and worn out. UV rays can also cause cracks and small pits on the surface. These issues get worse with stress or pressure. Keeping your spoiler out of direct sunlight helps it stay strong and shiny.
Environmental Causes of Fading
The environment also damages carbon fiber spoilers. Pollution, acid rain, and extreme heat or cold harm the surface. Here’s a table showing how these factors affect spoilers:
Problem Description |
Effect on Carbon Fiber Spoilers |
---|---|
UV rays cause fading, surface damage, and weaker material. |
These problems make spoilers lose their shine and strength. |
UV exposure creates cracks, pits, and discoloration. |
These flaws worsen with stress, leading to faster damage. |
Oxidation increases carbonyl and hydroxyl groups, reducing strength. |
This weakens the spoiler’s durability and heat resistance. |
Knowing these risks helps you protect your spoiler from harm.
Mistakes That Make Fading Worse
Some habits can make your spoiler fade faster. Using strong cleaning products removes its protective coating. Skipping cleaning lets dirt build up, which damages the surface. Parking in the sun without protection speeds up UV damage. Avoiding these mistakes keeps your spoiler looking new and strong.
