+x[Citar]+x[Citar]Gracias por su respuesta, en el momento de la resina, la indicación de que esta se utiliza para hacer llaveros con fotografías y otras opciones de múltiples productos, referencia adjunta. Los componentes de la resina son bisfenol A y epiclorhidrina, del endurecedor Monofenol B y polioxipropilendinamita. Compré productos EasyComposite y no quiero perderlos usando una resina mala. Gracias por adelantado.

Thank you for your response, regarding the resin, indicate that this resin is used to make keyrings with photographs inside and other options of multiple products, attached reference. The components of the resin are bisphenol A and epichlorohydrin, the hardener Monophenol B and polyoxypropylendinamita. I bought EasyComposite products and I do not want to lose them using a bad resin. Thanks in advance. Looking at the ingredients they are just standard components found in many a "bisphenol A" based epoxy so does not reveal much about the resins properties. The picture shows a typical application for a clear casting epoxy. If that is the kind of project you are trying to do then i would recommend our GlassCast Clear Epoxy Surface Resin as it can be poured in layers up to 15mm thick and deeper with multiple pours. Quite a few of our customers have used it with "waney edged" wood projects. Easy Composites / Carbon Mods - Technical Support Assistant

+x[citar]La proporción de cada sistema de resina es probable que el mar diferente en comparación con otros que ha utilizado. Es hasta la química que el fabricante utilizó en ese momento. Así que sí es posible tener una proporción de mezcla de 50:50 epoxi y no hay razón por la que debe ser una mala resina. Hay un montón de otros indicadores de la calidad de la resina en la hoja de datos de los fabricantes que deben ayudar a decidir si la resina es lo suficientemente bueno para el trabajo requerido.

The ratio of every resin system is likely to be different compared to others you have used. It is down to the chemistry the manufacturer used at the time.
So yes it is possible to have a 50:50 mix ratio epoxy and there is no reason why it should be a bad resin. There are plenty of other indicators of resin quality in the manufacturers data sheet that should help you decide if the resin is good enough for the required job.

+x[quote]Well that is the exact function of a core material. The flexural stiffness of a laminate is a function of thickness cubed, so you can exponentially increase the stiffness and add virtually 0 weight depending on the core material you choose. So that is why I asked exactly what you are making, because there are so many ways to go about this that it's impossible to recommend something without knowing the application. If you are infusing, you could do it all in one shot using an infusion core material like Soric or 3D PET Core, but this depends on the geometry of your part. If what you are making is virtually flat, then by far the highest performance option would be to use a honeycomb core (either aluminium or Nomex). Unless you are using pre-preg, this would need to be a two step process of making your skins individually and then secondary bonding them on either side of the honeycomb panel. Alternativamente, también puede añadir rigidez a la flexión a través del uso de la geometría (piense en la piel interior de un capó de coche). Con un diseño inteligente, esto puede lograr el mismo efecto de un material de núcleo, pero con una ganancia de peso literalmente 0. Otra opción de nuevo es crear una estructura de tipo "I-beam" utilizando longitudes de fibra de carbono entre sus pieles externas. Teoría tan similar a un material de núcleo, pero una alternativa útil si sólo necesita rigidez localizada en lugar de todo el laminado. Good morning, taking advantage of the question. I am from Peru and in my country I am offered to sell epoxy resin of 2 components A and B, but the proportions of the mixture are 50/50 is it possible these proportions? Thanks you!! Edgar

Alternatively, you can also add flexural stiffness through the use of geometry (think the inner skin of a car bonnet). With a clever design, this can achieve the same effect of a core material, but with literally 0 weight gain. Another option again is to create an 'I-beam' type structure using lengths of carbon fibre between your outer skins. So similar theory to a core material, but a useful alternative if you only need localised stiffness rather than the entire laminate.

Its more in the developmental stages before I spend serious money. The idea is to prevent flexing of a part by adding a structure but without making it too thick or heavy.

Well just bond them with a structural adhesive. Very hard to give advice without knowing exactly what you're making. Can you post pictures?

Hello. So I am looking to make a part for my watercraft. The part has two parts. Essentially a top and bottom (bottom piece would add a structure or rigidity to the part). Questions. Is my best bet to somehow (I am just spit balling here) add a "skeleton" structure between a bottom and top layer of carbon fiber OR should I build the two separate and "combine"? If I combine two parts, how do I do that? Do I infuse top part, bottom part and THEN do another infusion with pieces together? Is that possible? If not what is the best way to combine two parts? (example you have a cured part a and part b) Thanks for all your help. If I am talking crazy its the inexperience talking.
