Welcome to mpolyco

mpolyco is a free, offline toolkit for polymers, composites and mechanical engineering — trustworthy material data, validated calculators, and the science to understand it, from school-level basics to real design. Here's the fastest way in.

Find your starting point

I'm learning from scratch

No background needed. Climb one guided ladder from school-level basics up to real composite design.

Start the learning path →

I'm building something

Take a product from idea to spec: pick a material, pick a process, then design and validate it.

Go to Make →

I need a specific number

Look up a material's properties — every value cited to its source — or run a calculator on your own inputs.

Open the materials database →
What's inside

Everything links to everything — a material opens in a calculator, an article points to the tool it explains. The main sections:

MakeIdea → material → process → design, in one guided flow.Materials31 polymers, fibres and composites — every value with its source.CalculatorsLaminate theory, micromechanics, beams and vessels, unit conversion.SimulationsCreep, cure, failure envelopes and more, computed live.LearnPlain-language articles, ground zero to master, with self-checks.ElementsThe periodic table, and what each element does in a polymer.HandbookClassical engineering formulas, sourced and offline.GlossaryEvery symbol defined — and why that letter was chosen.
Why you can trust it
  • Every value is cited — source, test method and conditions, so you can check it and use it in a report.
  • Every model is validated against published reference values — not a guess with a nice interface.
  • Free, works offline, collects nothing — no account, no ads, no tracking.
