I've worked a lot with epoxy, in many different "flavours" so to speak, and found it to be very satisfying and rewarding, and you have demonstrated that a moment's thought can make an enormous difference. A particular favorite was an ultra low viscosity type for "potting" high voltage equipment, I look forward to more stuff about this material...cheers.

[@johnelliott4521]

I have used heat lamps to speed curing on larger structures sort of a home built autoclve. Vacuum bagging helps also on larger parts.

[@D2O2]

Best practice when glassing over wood or any other surface that will absorb resin is to wet the surface prior to placing the glass on top and wetting it out. Working with non-blushing epoxy eliminates the need for removing the amine blush. Laminating additional layers before full cure 24+ hours still creates a chemical bond and then no need to create a mechanical bond via tooth from roughing the surface.

[@michaellancina667]

The BEST fiberglass video I've seen! I did a boat repair project this summer and watched a bunch of YT videos - none of them explained the "wet-on-wet" technique as well as you did (not one mentioned the amine layer). Every video said to wipe down with acetone (and I think it was AFTER sanding).

[@pctrashtalk2069]

The popular homebuilt airplane designs like a Long-Ez, Cozy and others use epoxy and various foams to build up the structure. The plans give you detailed instructions on how to do it and it is very similar to this demonstration. You can wait until the epoxy is almost hard and easily cut off the overhanging cloth with a single edged razor blade for a nice edge which prevents much cutting and sanding later.

One of the things that a lot of people trying to do automotive panels with composites should learn is the basics of tensegrity that you touched on with your fiberglass reinforced foam. One of the easier ways to take advantage of that mechanism is to use foam or honeycomb structures to create a ribbing or webbing matrix on your fiberglass or composite panel, and then glass right over it. The foam being encased in your composite of choice will prevent it being the weak point by deflecting loads through the vertical sections of the enclosure, thus allowing you to bind two rigid surfaces into a structure wherein a compressive or tensile force applied to one surface is counteracted by a tensile or compressive force from the other by the forces being transmitted through the vertical support structure as a lever. It's like an I or H beam being more difficult to bend along its faces. These ideas are nowhere near new in the automotive world. Open the hood of any car and peel back the sound and heat isolation if it has any and you'll see an example of what I mean made out of stamped steel. Except with composites you can go a step further than auto makers can with their hood panels and you can bond the two layers together, enhancing the efficiency of that mechanism and further reducing the potential deflection of your panels. It's such a cool, easy trick that you rarely see used when people decide that they absolutely need to make a carbon fiber hood or fenders or whatever for their car, then they end up with a floppier panel or they have to use several more sheets of carbon fiber to reach the same stiffness.

There are so many different epoxy options that have huge variety in their curing time how are you to individually per epoxy basis know when the epoxy is in a great state that it can still form a good connection to new layer of epoxy? just a feeling of stickiness? also a lot of people use vacuum to draw out the air from wood for instance when they want to drench the wood in epoxy but it might not be practical at all depending on the scale of whatever you are trying to coat or get fully air out of. on a second not i would love to see a video where you compare materials available to home shops. lets say you want to build a bike frame or a little remote airplane. these kind of videos give a great insight on one way to do things but it would be great to have like a over all material introductionary video on what are some great materials that you can build realistically in your own garage to have an overview of what options are available in general. this is something i feel no channel really does that well. a lot of channels like applied siences etc do really great job in smaller areas but nobody really offers like a consolidated over view of different options available in lets say materials you could build a boat frame from. maybe there would be a demand for such videos too.

[@fraserlamb5787]

The Hardener just changes the speed of the chemical reaction so you get a set point time depending on temperature. Pot life is important for how long you can use the epoxy depending on the hardener and for most i think varies from 10 minutes to an hour. Epoxy should be good as long as it is sticky but lower temperatures really mess with it so you need heating below 15 celsius although west coast claims good results down to 3 celsius. it goes from Liquid, gel, hard and the final cure and full strength can take 36 hours or more. As long as you apply the next coat while it is sticky the cross linkinging should still occur. Humidity is a bitch too apparently and can cause problems with materials releasing moisture during the cure. Preheating the epoxy in a bath or hot box really helps kick start the reaction if working in the cold. Some Industrial stuff is set up so it has a post curing phase that you heat it to finish to cure but i do not think most of that is available to us plebs. i got the number for the sale rep for my country who was a wealth of knowledge. I used West Coast who have good information for home use but Sicomin Epoxy Resin is around 20-30% Cheaper if you can find a source and apparently is used very heavily in my country. But information is harder to come by so it's worth just asking reps if you can find contact info. For comparison i paid £110 pound for 6kg West Coast and £90 For Sicomin at the same volume.

All of these are classic surfboard glassing/repair techniques. I think this is the best vid I have ever seen on the topic, very concise and clear. Surfboards are typically a lightweight PU core with polyester resins with fiberglass -- stiff outer shell around a lightweight core... the techniques are exactly the same as here. Surfboard lineage is shared with boats and airplanes. Other minor techniques: - orienting cloth, cloth is anisotropic so you want it diagonal to the direction of shear to get max stiffness, and layering cloth in different directions to produce a more homogeneous result - adding filler like microbeads to fill gaps/holes in an uneven material while keeping weight/material cost down - slow cure = generally better strength, I think? I have heard this but I'm not sure about it.
