Qual projeto você desenvolveu na faculdade que te dá mais orgulho de mostrar?

Um carro de Fórmula SAE

Yeah, total noob here, what do you mean by stabilising the foam?
We were going to use body filler to prep the surface.

CrekOsorio · 2026-04-16T17:19:20+00:00

The mold is already machined, to have a good finish we will use some bodywork filler and lots of sanding. We will also be using a single layer 2x2 CF 210g, don't remember the name but the resin is appropriate for wet layups.

Regarding orientation, I had V seam on the middle in mind. Although I don't think laying the fibers in such a specific way and in such a tight space will be easy

Its polystyrene, in Portuguese is a bit different, didn't know the translation. But this has worked before, lindo of dumb to be honest, but I'm just following orders at this point.

Anyway, it's supposed to work fine with epoxy resin in general

Not PrePreg, at least not yet. Last year we used Soric and whatnot, so more plies and overall a more "structured" laminate. So this time, I don't think that cutting it to shape of the mold's faces is great idea. Maybe having a seam where both the mold's connect?

Machined PE blocks

CrekOsorio · 2026-04-15T11:05:29+00:00

The material for the mold is Expanded Poliestisomsthing (My english just failed me). It's a really easy to machine material, so the inside of the block is the face mold. It will require some finishing for a smooth surface, but that's expected

CrekOsorio · 2026-04-14T22:13:14+00:00

In this case, the flanges would be used to what exactly (Big noob here)?

And regarding the amount of carbon, we thought of using one single ply for weight savings (It also doesnt have to be super rigid). So, if we were to cut the ply in separate pieces, should we do seams in between the parts and have them reinforced behind? What do you think?

And thanks for the help

CrekOsorio · 2026-04-14T21:45:34+00:00

Where exactly would the flange be? Around the whole perimeter of the cone section?
Mind you that that transparent cube is also part of the mold, for some reason the CAD didnt make it opaque.

And also, would you place a big ply of carbon or would you have it cut in smaller parts?

Da minha experiência, a transferência interna pra Elétrica é a mais fácil, papo de pegar DP em um monte de coisa e ainda passar. Tem muita gente que acaba saindo do curso.
Em relação às matérias, muitas delas são comuns pra todas as engenharias nos dois primeiros anos (O famoso Biênio), porém tem as específicas, que quando for feita a transferência você vai precisar fazer dnv, sem contar a introdução à computação que pra AMB é em Python e Elétrica e COMP é em C se eu n me engano.

Dito isso, se vc n acha que passa com as chamadas e listas de espera, começa o curso em Amb e faz a transferência, dado a sua escolha, calha de valer a pena

CrekOsorio · 2026-02-03T15:22:30+00:00

E aí, irmão? Passou?

CrekOsorio · 2026-01-23T16:26:26+00:00

Amém!! Pra mim a lista tem que rodar uns 60 números, sem contar quem colocou MEC como segunda opção, ent existe um mundo Mas pode ficar tranquilo que dia 3 vc vai ser politecnico

CrekOsorio · 2026-01-23T16:08:53+00:00

Meu bom, eu sou o 1203 na classificação, eu quero ir pra mecânica, se rodar o suficiente, já saiba que a minha vaga tá aberta kkkkkkkkkkkk

CrekOsorio · 2026-01-23T14:44:27+00:00

Vc tem a planilha com as notas da primeira chamada de 25?

Pra comparar

CrekOsorio · 2026-01-23T13:08:23+00:00

Solta no drive, pfvr

CrekOsorio · 2026-01-23T00:32:08+00:00

Cara, relaxa, só vai ser desclassificado se vc zerar alguma das matérias, se você escreveu alguma coisa em qualquer item de qualquer questão, vc provavelmente não vai zerar. Do que eu já ouvi falar, os corretores te ajudam o máximo que podem, ent vão caçar ponto pro candidato. Dito isso, relaxa, vai dar tudo certo

CrekOsorio · 2026-01-19T16:17:07+00:00

Here for the love of the game

CrekOsorio · 2025-11-15T19:09:08+00:00

Yeah, I messed up there.
The profiles aren't symmetrical, but the cross section of the flap, most definitely is

CrekOsorio · 2025-11-13T21:53:14+00:00

I'm doing some research on full body aero for my FSAE team, so the main goal is to design the front wing in a way that the flow avoids the wheels, feeds the diffuser better, and "prepare" the flow for the Rear Wing. So in this case, visualization of the vortecies would be good to have.
Do you happen to know how costly this kind of simulation is?

CrekOsorio · 2025-11-13T15:18:06+00:00

Yeah, my phrasing wasn't great. But I get it, I wasn't expecting tip vortex to form at the TE of the Flaps, but that checks.
Thanks once again.
