How to Make Carbon Fiber: A Simple Guide

Kas ir oglekļa šķiedra?

Oglekļa šķiedra is a strong and light material. It is made of thin strands of carbon. These strands are even thinner than a human hair! Carbon fibre (also spelled this way) is used to make cars, bikes, planes, and sports gear.

“Carbon fiber is five times as strong as steel but weighs much less. This makes it perfect for things that need to be both strong and light.” – Engineering Expert

Why Use Carbon Fiber?

Oglekļa šķiedra has many good points:

• It is very strong
• It is very light
• It does not rust
• It can be shaped in many ways
• It looks cool

This is why many people make carbon fiber parts for cars, bikes, and other things.

What You Need to Make Carbon Fiber

To work with oglekļa šķiedra, you need these tools and materials:

Basic Steps to Make Carbon Fiber Parts

1. Plan Your Project

Before you start with oglekļa šķiedra, you need to know what you want to make. Start with simple shapes. Big or hard shapes can be time-consuming.

2. Make or Get a Mold

The pelējums is what gives your oglekļa šķiedras daļas their shape. You can:

• Buy a ready-made pelējums
• Make one from wood
• Use an old part as your pelējums

Put release wax uz jūsu pelējums tātad oglekļa šķiedra will not stick to it.

3. Cut the Carbon Fiber Fabric

Carbon fiber fabric comes in sheets with different aust types. The most common is a sarža pinums pattern. Cut the fabric to fit your pelējums plus a bit more around the edges.

4. Mix the Resin

Epoksīda sveķi is what makes the oglekļa šķiedra hard and strong. Most sveķi comes as a two-part mix:

1. Pour part A and part B in a cup
2. Mix well but not too fast (to avoid gaisa burbuļi)
3. Use it soon, as it will start to get hard

Be safe! Wear gloves when you work with sveķi.

5. Wet the Carbon Fiber

Tagad nāk slapjš salikums solis:

1. Put your oglekļa audums on a flat spot
2. Use a brush to slapjš the fabric with sveķi
3. Make sure all the oglekļa šķiedra gets wet
4. Do not use too much sveķi – just enough to slapjš all the šķiedra

6. Place on the Mold

Ielieciet slapjš oglekļa šķiedra uz jūsu pelējums:

1. Start from one end and smooth it down
2. Push out any gaisa burbuļi
3. Add more layers if you need a stronger part
4. Each new layer is part of the izkārtojums

7. Remove Extra Resin

Pārāk daudz sveķi makes your part heavy and not as strong. Use a plastic tool to push out extra resin.

8. Apply Pressure

You need to compress uz oglekļa šķiedra as it dries:

• Izmantojiet a vakuuma maisiņš method
• Or use skava and flat boards
• Or try vakuuma infūzija lielām daļām

9. Let It Cure

Now you wait for the sveķi uz izārstēt:

1. Check your sveķi box for izārstēt laiks
2. Most take 24 hours at room heat
3. Keep the part still while it cures
4. Some people use karstums un spiediens uz izārstēt ātrāk

10. Remove from the Mold

Pēc sveķi is fully hard:

1. Take off any wrap or bags
2. Gently pull the finished part from the pelējums
3. Trim the rough edges
4. Sand any spots that need to be smooth

Oglekļa šķiedras veidi

Ne visi oglekļa šķiedra is the same. Here are the main types:

• PAN (made from polyacrylonitrile)
• Pitch (made from oil)
• Rayon (tagad retāk)

Most home users work with PAN-based oglekļa šķiedra.

Different Ways to Make Carbon Fiber Parts

There are a few main ways to work with oglekļa šķiedra. Here they are, from simple to hard:

Wet Layup

This is what we just went over. It is the most common way for home users to make carbon fiber parts.

Pre-preg Method

Pre-preg vai iepriekš impregnēts oglekļa šķiedra comes with sveķi already in it. It needs to:

1. Stay cold until you use it
2. Be heated to izārstēt
3. Often needs an autoklāvs (a big hot oven)

This is how many pro carbon fiber reinforced parts are made.

Vakuuma infūzija

With this method:

1. The dry carbon fiber fabric is put on the pelējums
2. It is sealed in a bag
3. Air is sucked out
4. Sveķi is pulled in to infuse all the šķiedra

This is good for big parts and can give very strong results.

Making Real Carbon Fiber from Scratch

The steps above show how to work with carbon fiber fabric that is already made. But how does oglekļa šķiedra itself get made? Here is the manufacturing carbon fiber process:

1. Start with a polymer patīk polyacrylonitrile
2. Pull it into thin diegi strings
3. Heat these strings at high heat without air
4. This turns the strings into ogleklis
5. The carbon fiber starts out as single virtene šķiedras
6. Šīs ir woven into a fabric

This needs specialized equipment and is done in factories.

Safety Tips When Working with Carbon Fiber

Working with carbon fiber can be fun but you need to be safe:

• Wear gloves when touching sveķi
• Wear a mask to avoid breathing oglekļa šķiedras putekļi
• Darbs telpā ar labu gaisa plūsmu
• Keep food away from your work area
• Clean up spills right away

Projects to Try

If you want to learn how to make carbon parts, start small:

1. A simple flat plate
2. A phone case
3. A small box
4. A bike part

As you get better, you can make more complex oglekļa šķiedras daļas.

Biežākās kļūdas, no kurām jāizvairās

Many people make these mistakes:

• Using too much sveķi
• Not getting all gaisa burbuļi ārā
• Being in a rush during izārstēt laiks
• Making a part too thin and weak
• Trying a too complex shape for your skill level

How Carbon Fiber Compares to Other Materials

How does oglekļa šķiedra stack up to other engineering materials?

Where Carbon Fiber Is Used

Carbon fibre is used in many places where a lightweight material is needed:

• Aviācija parts for planes
• Automašīna racing parts
• Sporta preces piemēram, tenisa raketes un golfa nūjas.
• Bikes and bike parts
• Medicīniskās ierīces
• Music equipment

Advanced Carbon Fiber Methods

If you get really into oglekļa šķiedras ražošana, you might try:

• Using a CNC to make precise molds
• Pagatavošana augstas veiktspējas parts with special layup patterns
• Adding other materials to make composite materials
• Using different types of sveķi patīk polyester resin vai thermoset veidi

Pēdējās domas

Making things with oglekļa šķiedra can be fun and rewarding. Start simple, be patient, and soon you’ll be making amazing oglekļa šķiedras daļas!

The complexity of the part will decide how hard it is to make. With practice, you can make cost-effective un forši finished product items that are both strong and light.
