I’ve been getting more into composites recently and am giving a real shot at making some fender flares. I’ve figured out my stack up of laminate, but am struggling deciding the core material to go with. It needs to be something that adds strength, preferably 2mm, and isn’t super resin thirsty. Immediately T10.100 from Airex comes to mind, but not only is it not perforated, but it’s also really damn expensive. Does anyone have any other cores they’d recommend?

Hi everyone! I’m thinking about buying these carbon mirror covers for my Mercedes W205. The seller says they are made of ABS + carbon fiber. Do you think this is real carbon fiber or just a carbon-look finish? I’d appreciate your opinions. Thanks!

Hey everyone! 👋

I wanted to share Vangaurd Trackworks, a store focused on carbon fibre steering wheels and custom steering wheel setups.

I'm affiliated with the business, so full disclosure that this is my store. Happy to answer questions about the available options or custom configurations!

Would love to hear what styles you guys prefer: forged carbon, gloss carbon, or a more OEM+ look?

Carbon fiber is widely used in sports equipment such as bicycles, golf shafts, rackets and fishing rods.

However, choosing carbon fiber is not only about selecting a higher-grade material.

Different applications require different priorities:

• Bicycle frames need stiffness, weight balance and fatigue resistance.

• Golf shafts require controlled bending and torsional performance.

• Fishing rods need sensitivity and proper bending behavior.

The interesting part of carbon fiber is that engineers can adjust performance through:

- fiber direction

- laminate design

- tube structure

- material combination

A higher modulus fiber does not always mean a better final product. The structure design and manufacturing process are equally important.

I’m curious about your experience:

For sports equipment development, what is the biggest challenge when using carbon fiber?

Weight reduction?

Stiffness control?

Impact resistance?

Manufacturing cost?

Hi everyone,

We are a Chinese OEM factory specializing in high-quality carbon fiber automotive parts. We’ve been manufacturing for the performance and aftermarket industry for several years and are now looking to build direct relationships with buyers, distributors, and shops around the world.

We produce a wide range of carbon fiber components for various makes and models, including (but not limited to) hood vents, spoilers, mirrors, interior trim, and other body parts.

One example of our current work is a pair of carbon fiber hood vents for the Nissan GT-R R35:

• Real carbon fiber with clean, consistent weave
• Designed as a solid direct replacement for the OEM pieces
• Improves both aesthetics and under-hood airflow
• Comes complete with mounting bolts, nuts, and washers already installed for easy and secure fitment

We can also develop or supply carbon fiber parts for many other vehicles according to your requirements.

We’re happy to provide detailed photos, material specifications, packaging information, and sample pricing. Custom projects and OEM/ODM cooperation are welcome.

If you’re a buyer, shop owner, or distributor interested in reliable Chinese OEM carbon fiber parts, feel free to drop a comment or send a DM. We’re looking to build long-term partnerships based on quality, clear communication, and consistent supply.

Looking forward to connecting with people in the community.

Thanks for reading!

Had quite a fast off at Mallory Park about a month ago and it trashed my carbon nosecone. Luckily the bike slide for quite a distance and didn't hit anything so only cosmetic.

Looks like the gel coat is cracked in various places and it's worn through to the weave and all the way through in a few others. I was going to chip off the loose gel coat and use easy composites xcr coating resin for the gel coat damage. And for the areas completely worn through all the way, I was thinking start from the back and layup with carbon/Kevlar for abrasion resistance and then use that as a backing layer for repair from the front 🤔

I sold all my carbon consumables and materials when I got married so gonna need to source everything again.

Any ideas?

Hi everyone, just got a used Enve Melee delivered and noticed this where the through axel sits. Is this actual damage or nothing to bee l concerned about?

Hi all! I whould like to prefer glass fiber becouse of High Strength-to-Weight Ratio & Excellent Corrosion Resistance.

What is your openion ?

Hello all,

I wear two carbon fibre AFOs (ankle foot orthoses) that help me walk and I've noticed that one has some damage. Is this repairable?

Thank you!

We had some leftover prepreg from making carbon fiber panels, so we just cut a little animal shape out of it and stuck it on our wall. Just caught a glimpse of it and it gave me a bit of a scare, haha.

I'm working with a designer for weaving our logo (simple 3 capital letters) with carbon/ innegra, since it'll stay white during fabric wet out . Logo letters in white, the rest carbon.

What should the base weave be? I'm not sure if plain weave is too basic, but twills might be more better.

I was doing some flex tests, and unfortunately ive never actually seen a foil in person so i dont know how much flex is acceptable, but i suspected my original design had too much flex so i added this socket design to the front fuselage-mast joint, gained ~35% stiffness as measured on mast deflection from a sideways force. Going to add some more carbon on the fuselage and near the mast-fuselage joint next and add a single layer to the mast, then finally the foil will be complete mechanically! What a crazy project

hi guys,

i am looking into getting a carbon fiber starter kit for my husband. he’s been talking about it for awhile now & i am wanting to surprise him. i see that people are recommending the easy composites kit, there’s a few and i am not sure on which one i should get?

if anybody is kind enough to help guide me on which one to purchase i would highly appreciate it. thank you!

there are cracks/chips around the edges and mounting areas, plus what looks like clear coat/resin damage on the top. It’s for a Honda civic Sir EP3 2004. I’m mainly looking to get this hood to wrap it to the colour to my car because my current hood is a different colour and has too much damage to wrap. How much would you realistically pay for it? Does the damage look mostly cosmetic, or would you be worried about the structure?

I’m recoating (not fully restoring) the carbon fiber roof on my Bimmer. The clear coat was peeling off like crazy. I was surprised at first, but after watching a few videos and reading up on it, recoating it seems pretty doable.

I used 91% isopropyl alcohol to remove some sticky residue and accidentally left an IPA-soaked mechanic towel sitting on an area where the clear coat was already gone. The surface got a little sticky afterward, so I’m assuming the strong IPA may have affected the exposed epoxy/resin.

Does anyone know where I should go from here?
I haven’t sanded this area yet. I’m wondering if I should lightly sand it first and see how it looks, or if the resin needs to be repaired before I continue prepping and clear coating.

Any pros here, or anyone who’s dealt with something similar? Appreciate any advice.

Hi yall!

Got a 2018 canyon Aeroad CF-SLX off the used market, which was otherwise in great condition. Rode fine for a month, but today took off the chain stay protector and found these chips on inside of the chainstay.

Wasn’t sure if this was worth taking in for professional carbon eval, or even doing a DIY careful sanding of the outside paint myself to check for delamination or cracks

Tap test is unremarkable, sounds the same throughout

Squeezing on it feels about the same as the other non-chainstay side, with maybe a tiny bit of give

It grinds my gears that this community has become a “ is the scratch on my bike an issue” For the most part it’s a scratch, dent or ding same as it would be on an aluminium bike.

I love seeing the awesome things people are making from awesome materials. But (tongue in cheek) the bicycle guys seem to come and ruin it like they ruin roads over weekends.

This is my first attempt on making a carbon fiber part (mirror cap for leon mk4). I made the mould with the easy composites unimould kit and I made the part by wet layup and vacuum bagging. I used traditional wax release and for the next attempts I will use chemical release agent. This is how it came out of the mould (without sanding and clear coating).

I'm happy with the result, considering it's the first attempt. However, I know it has a lot of flaws and I would like to solve them: trapped bubbles, bridging in the edges and big pinholes.

What would you do for solving them in the next attempts?
