    Introduction to the forum: I look forward to helping and learning!

    Hello everyone, I'm new to the forum and eager to learn more about a wide range of topics. My background is in Non-Destructive Inspection (NDI), but lately, I've been researching the world of composite materials. It's been fascinating to explore how NDI techniques can contribute to ensuring the...

    Carbon Fiber Rocket Gallery

    There isn't already a thread about this, so I decided to make one. Post a pic of anything both carbon fiber and rocketry related. I am working on a carbon rocket currently but I don't have the carbon fiber on it yet. I will post a pic of it once the rocket is finished. Enjoy!

    X-Winder Creating Incomplete Parts

    I am working with a 4-axis X-Winder in 2X mode. I have successfully wound a 3.5-inch mandrel many times however am now struggling to wind a ~12-inch mandrel (we have the 16" expansion kit). The software claims to be 100% done with the wind but in reality, the part is 95% done (see photos). Has...

    Carbon Hyperloc 835 Build

    Hi All, After building more Estes rockets than I can count, I decided to build my first HPR. For Christmas I purchased a Hyperloc 835 kit that I will hopefully be able to get my L1 cert (maybe L2?) with. To make things interesting I decided to sheath the body in a light carbon fiber sleeve sold...

    Min-Diameter Launch Lug Options

    For some context, I'm building a 98mm min-diameter carbon fiber rocket that's outlined in my build thread. I'm not 100% what launch lug options are available for these types of rockets. I've seen people build their own launch towers that don't require launch lugs for smaller-sized rockets...

    98mm Min-Diameter Composite Mach 3 Build

    Hi everyone, I just wanted to get people's opinions/tips on a "little" project that my college rocketry team is working on. Intended to test our manufacturing capabilities in hopes that the lessons learned can be applied to our much larger competition multi-stage rocket, this project is...

    My King Dragon Star Explorer build

    King Dragon is making small carbon fiber rockets, so I thought I would build one. This is the Star Explorer, parts washed, then scuffed and scratched, i.e. prepped for epoxy. I used Rocketpoxy, with a few drops of black dye, an old screw eye out of my repair pile and the fin guide also from King...

    Do Carbon Fiber Layers Effect RF Transparency?

    I'm new to RF telemetry, and I bought a 3DR Telemetry module recently. I built some custom carbon fiber tubes which is composed of 1 layer of fiberglass and 1 layer of carbon fiber (I know that's a horrible idea because they have different properties, but I did it because I wanted wiring to be...

    Carbon fiber tubes

    Working on plans for min diameter 98mm vehicle. What ID does the tube need to be to catch the aft closure? Motor casing on forward end will be screwed in. Thanks

    Painting CF, FG, and ABS Airframe

    Hi all, I've never done a spray paint job with any sort of precision before, so I hope you'll excuse that I don't know a lot. I just want to be as informed as possible to do as close to perfect a job as I can. My team has a 12ft long rocket with a 7.78" diameter fore section that transitions to...

    Help IDing CF vs Fiberglass?

    The other day, I was generously donated some spare 4" body tubes (and one coupler) for building an L1/L2 bird. However, I'm not entirely sure what they're made of, and because they're black, they don't photograph too well. Things I know: They're from Madcow Rocketry. They're 60" long and 4"...

    CF airframe + alu skin on a supersonic rocket?

    Hey everyone! First poster here. I'm an absolute newbie to this subject who just learned about it a few days ago, so have mercy on me if I'm wildly off the mark here with my question: In the search for a lighter rocket, has anyone built a supersonic rocket which has a carbon fiber skeletal...

    Composite curing DIY oven

    I am looking to expand my carbon fiber experience with prepreg and or post curing of composite components and sub assemblies. Specifically I am looking to try rolling tubes, creating plate, and creating fincan assemblies. However as some of you know this requires an oven that can be reasonably...

    Carbon Fiber Newbie Questions

    I've attempted in vain to research the answers I'm seeking on this forum, Google searches, etc. So here goes nothing. Pardon the newbie questions. I'm attempting to build my first ever rocket with a carbon fiber airframe. The desire isn't based on flight profile, but rather aesthetic reasons...
