bcRPN vs Laminate Calculator

This is a RPN (Reverse Polish Notation) Calculator. It supports complex numbers and uses extended precision math for all operations. The stack depth is unlimited. In case a mistake was made, up to 10 operations can be undone. RPN calculators work by entering the numbers on the stack first, then selecting the operation. For example to add 3 + 4, press: 3 Enter 4 +

Laminate Calculator is a practical tool for designing composite laminates and estimating laminate thickness, fibre and resin requirements, and final laminate weight. Build your layup layer by layer, define the laminate area and manufacturing process, and instantly see useful design estimates. _____________ CALCULATE • Build multi-layer composite layups • Estimate laminate thickness • Calculate fibre areal weight and fibre mass • Calculate mixed resin requirement • Calculate total laminate weight • Enter dimensions or laminate area directly • Choose hand lay-up, vacuum bagging or infusion • Adjust fibre volume fraction and waste allowance • Work in metric or imperial units _____________ USE YOUR OWN MATERIALS Laminate Calculator includes built-in materials to help you get started, but you are not limited to them. Create your own reinforcement materials using the actual properties of your fabrics, including fibre type, areal weight, fibre density, supplier and product code. You can also create your own resin systems with custom mix ratios, mixed density, supplier information and technical notes. This makes the calculator suitable for carbon fibre, glass fibre, aramid and other reinforcement materials, as well as the resin systems you actually use in your projects. _____________ PRO Upgrade to Laminate Calculator Pro to unlock additional tools for regular use: • Create unlimited custom fabrics and resin systems • Save laminate designs for later use • Build your own library of projects and constructions • Reopen and edit saved laminates • Export your materials and saved laminates as JSON • Import JSON backups whenever needed _____________ YOUR DATA STAYS YOURS Your laminate designs and custom materials are stored locally on your device. Laminate Calculator does not require an online account or cloud service. With Pro, you can export your own data as a human-readable JSON file and import it again whenever needed. Whether you're sizing a foil wing, boat part, automotive panel, surfboard, moulding or another composite structure, Laminate Calculator helps turn your layup plan into practical thickness and material estimates. Calculations are estimates. Always verify material properties, processing parameters and final design requirements against your material supplier's technical documentation and your own engineering requirements.
