In this course, we will get you started with working with Fiberglass material effectively to reinforce foam and other core material as part of a introduction to a key subject once the learner has the the structural experience, confidence and know to build and construct experimental aircraft for beginners on gaining a better view of the process to begin working with fiberglass yourself should you have the assistance or supervision or are capable yourself to try out a few simple tries on your own.

Course Coverage:

  • This introduction course is condensed into a short 1-hour long "over-the-shoulder" workshop covering a DIY guide to reinforcing foam cores with Fiberglass.

  • To get you started sharing these skills from the experience of an experimental aircraft builder, where in the past we have worked to build our own aircraft from plans, experienced helping others build theirs, as well as build conceptual water tanks for automobiles, water bowls for wild birds, even as small as postboxes.

  • Each lecture covers a topic in the process, where we cover the basics in short 2-minute lectures so you can follow along and take notes.

  • We don't cover the topic of makings molds in this course, though these skills can be used on certain molds which would act as cores to apply Fiberglass.

  • However, we do demonstrate how wings and structures such as "canards" used on aircraft are cut from foam, which are the cores to which Fiberglass gets structurally applied in Aircraft design.

It has many applications in DIY repairs, even in the structural design for marine vehicles like small boats. In this course, we will cover the basics of Fiberglass in practice, working with it, and how to apply it relatively quickly and effectively.

Although we don't cover the topic of makings molds in this course.

For many, the subject of "Fiberglass" and "Composite Materials" may come to mind. Fiberglass tends to be heavier than Carbon Fiber, however it is known to be cheaper, and why many use it.

Further Considerations:

Have you thought of a creative or great use case in which you could use this material yet? Don't worry, you'll think of something good.

Though of course before practicing or learning anything new, first things first, think and practice safety, always.

Some may think when covering the course, that before 3D printers became popular, this building thing from Fiberglass was sort of an analogy to the hands-on manual process of doing so that many users still use today to complete many projects.

Even 3D printers can take their time, and do not be fooled some Fiberglass projects can be challenging to build from scratch also the bigger scale the projects is as well as depending on your resources could stretch into years, even decades for some for example when it comes to building aircraft, though with the right experienced team all working together safely and innovating, some people have done amazing things in a short period, and with the extra experienced support it could be both fun and rewarding doing so when everything goes to plan.

Student Background:

  • No matter prior experience, so long as you approach with responsible care and safety, this may suit a creative DIY hobbyist or enthusiast, interested in building aircraft from plans ( though we only mostly cover Fiberglass basics).

  • The more experience you have in an area to use these skills, the better and quicker you may understand and adapt, though everyone learns something from scratch at some point.

  • With a willingness to learn and apply patience from beginner to intermediate you'll be able to take notes and is recommended to complete the course and have taken notes and planned ahead before practicing,

  • unless of course, you feel comfortable and just refreshing your memory by taking this course.  

  • Adult supervision is advised for younger students.

  • Should you be taking this course to apply these invaluable skills to a personal project, then having a background and or understanding of a "Materials" or "Structural" design will be advantageous to how you approach the task at hand in making your considerations for specifications in what materials are best to use for the project.

Value:

  • Depending on what creative ideas you already have in mind, with the right know-how just like you would be getting started here, because of the many hours required on some large projects, and working with the right clients they may even get you up to speed such as if they see you are a willing apprentice that understands and is able to use the skills safely and correctly to help them on their projects.

  • These fundamental skills can be used to create things from scratch or repair things like plastic bumpers and so forth, or as part of manufacturing certain cosmetic replacement parts that fit vehicles, even certain aircraft, DIY postboxes, and so forth.

  • You can even find ways not mentioned to create your own value.

SAFETY  We expand a little more in Chapter 0 after the introduction.

Safety Gear:

  • Wear long-used overalls. (These must be dusted/vacuumed off and washed separately in a bucket and kept out of the home)

  • Wear safety goggles/glasses that cover your eyes to help prevent you from touching them and from splashes or dust.

  • Wear a workshop respirator/particle mask that also covers the nose.

  • Wear thick rubber nitrile gloves.

Safety Disclaimer

  • Powders and material fabric used in Fiberglass contain tiny glass particles or otherwise can end up sharp and cut you if breathed in, comes in contact with skin, hands, eyes or swallowed.

  • Always ensure your hands are clean before touching yourself, objects you may accidentally contaminate, or others.

  • Resins and hardeners have the same toxic hazardous carcinogenic danger if at all come into contact with skin hands or eyes or are ingested.

  • Pay careful attention when purchasing these products to do research with your supplier for the safety and storage data sheets.

  • Requires immediate action to rinse if in contact with eyes, and flush out with eyes open for 15 minutes under normal/warm water while doing so seek emergency help and care with a copy of the substance label so Medical Professional can immediately treat you as symptoms may not show up immediately.

  • Hands can be washed under warm soapy water thoroughly.

  • Vacuum any dusk particles from the workspace.

We as instructors cannot claim responsibility for any harm or injury whatsoever or as a result of any exposure or lack of precaution taken when following this course, it is the onus of the student/consumer of this course material to avoid any neglect or abuse, and to practice and use these skills in a safe and ethical manner as responsibly as possible.your

Introduction
Basic Safety Gear:

STUDY GUIDE ***ALWAYS READ SAFETY LABELS and SAFETY DATASHEETS**

It is good to note that VERY HAZARDOUS materials and chemicals are used in practice that is DANGEROUS should you or anyone come IN CONTACT, SWALLOW or INGEST, BREATHE IN, or GETS INTO anyone's EYES.

It is a good simple rule to wash up and take great care and caution, by wearing the appropriate safety gear, at all times to protect yourself and others from accidental contact or exposure in these areas.


These are just the basics, it is good to know them all and research further how to better protect you and others! (Scroll Down for more below...)


SAFETY GEAR

- Workshop particle dust mask (or "Respirator", Must also cover the nose, to protect from sanded foam, fiberglass particles, epoxy resin/hardener fumes or splash, or glass powder exposure. Protect your airways and lungs!)

- Thick rubber gloves like Nitrile or thicker (That won't break easily as fiberglass can cut you, to also protect hands from epoxy resin/hardener, powders, and resin mixes. Protect your hands and skin and NEVER touch your eyes!)

- Safety glasses/goggles (To protect eyes from accidental epoxy resin/hardener splashes, fiberglass splinters, sanded foam, glass powder, or touching your eye with exposed hands/gloves. Protect yourself from going blind!)

- Long sleeve overalls (To cover from skin contact)

- Sufficient ventilation where working

- Vacuum and get rid of any dust safely or particles off clothing, and keep it out of the house


MILD SYMPTOMS INCLUDE (Anything you touch or handle can contaminate it.)

- Swollen eyes that burn and/or swelling

- Lung irritation

- Blisters and burns

- Red skin, swollen face

(De-contaminate, remove any dust particles off clothes and workshop, ensure gloves are removed and soaked in warm soapy water before the epoxy resin hardens, wash hands also thoroughly separately for safety even if no contact. )


MORE SERIOUS and/or PROLONGED EXPOSURE without safety measures

- Would lead to cancer

- Would lead to lung disease

- Other serious symptoms would occur


FIRE RISK

- Fumes can ignite with a spark!

- It is good to have a powder or foam fire extinguisher on hand!

- When mixing "Fiberglass epoxy resin and hardener" a properly designed "Epoxy Resin Scale" and "Balancing" of the two together and the order you put them in,  ensures the correct "Epoxy Resin to Hardener" ratio., violating this ratio can cause a fire!

- NEVER think if you add more hardener than the ratio of properly manufactured scale defines for mixing epoxy resin requires that it speeds up the time, it won't, and it can literally catch a flame!

- It is good to only mix SMALL quantities of epoxy resin and hardener to make epoxy resin mix on the epoxy resin scale, as mixing too large a quantity can also heat up and cause a fire!

- It is good to have a fire extinguisher nearby, and also never leave the epoxy resin or hardener bottles open, or where can break and fall over or to the ground, and never leave mixed epoxy resin unattended, rather mix small batches when working with it correctly so that you can use it all up on the sample you working on!


TREATMENT:

Forbid any liquid splashed into your eye, and get help while you begin flushing out with clean hands under a running tap immediately for at least 15 minutes while lifting your eyelid so water can flush as much out! Ensure you have a snapshot on hand of the label on the bottle of whatever splashed into your eye when seeking medical help!


If getting onto your skin, wash/rub off with warm soapy water immediately, if any major issue ensures you have a snapshot of the product labels of what got onto your skin to take with you to seek medical attention.


AFTER WORKING:

Decontaminate and wash up by taking your thick gloves or nitrile gloves (don't use latex) off carefully,

with clean exposed hands hopefully, your safety goggles are still clean, as well as your mask and having vacuumed of any dust from working, and on your clothing, you can then take off your safety glasses and mask.

Now WASH YOUR HANDS THOROUGHLY and get your overalls into a bucket of hot water separate from ordinary washing, add detergent, and soak and wash thoroughly, rinse and hang up to dry!

Ensure hands are clean again then just be aware and try to make less contact with things out of caution, don't touch people or things unnecessarily until you become more habitual or comfortable that you have not contaminated your hands or anything else.


before eating or drinking - WASH YOUR HANDS THOROUGHLY

before smoking - WASH YOUR HANDS THOROUGHLY, and get away from flammables, go outside!

before using the lavatory/restroom - WASH YOUR HANDS THOROUGHLY
