VectorLam closes the gap between theoretical answers and real world application
When your laminate design questions concern stiffness, strength, weight, and cost VectorLam can help you find the right answers. Whether it’s the materials, the resin, or even the manufacturing process, VectorLam offers the best solution and can report it in a clear, concise language.
The VectorLam program is based on Classical Plate theory with a twist; the answers are derived through reverse calculations of actual tested materials. New materials can be generated with precision through a process of cloning, allowing the user to create, modify, and delete materials with ease.

VectorLam accurately predicts laminate physical and mechanical properties fabricated by any process. From open mold and chopper gun methods, to vacuum infused and autoclaved laminates. VectorLam allows the user to adjust fiber and resin contents, manipulate fabric architectures and orientations, and modify resin properties to accurately estimate real world composite laminates.
Save Time, Save Money
Showing how different material selections can help speed production and reduce labor is one of VectorLam’s key functions. While navigating through the maze of materials to meet your stiffness and strength requirements, VectorLam helps to reveal cost effective solutions to optimize the number of layers needed to meet your specific objectives. VectorLam provides the link between finished laminate cost and the cost of labor.
- Create up to 14 different laminates for direct comparison of strength, stiffness, weight and cost. A maximum of 20 individual materials can be used to build each laminate.
- Create your own resin systems.
- Build carbon, aramid, E-glass, and hybrid reinforcements. VectorLam also includes an extensive database of core materials, woods, plastics, and metals.
- Design unidirectional, biaxial (±45° or 0°/90°), triaxial, and quadraxial reinforcements. Each materiall allows 5 axes at any angle between 0º and 90º.
The “Plate” page calculates laminated properties with respect to the panel size in two dimensions. Incorporating panel size enables an accurate computation of stresses and deflection for a plate under a uniform pressure with simple supports. The “Plate” page accounts for the properties of the core material (if used) and laminate skins to calculate the failure modes and safety factors critical to the panel design.
The “Stiffener” page uses classical beam theory to predict stiffener deflection, strength, and buckling safety factors according to DNV High Speed Craft rules. The calculations take into consideration the stiffener geometry, end conditions (fixed through cantilever), and the selected laminate properties. Here you can see the effects of unidirectional fiber on the stiffener cap and double bias fiber on the shear webs.
"The DNV (Det Norske Veritas)" page uses equations from the High Speed, Light Craft and Naval Surface Craft rules created by DNV. With VectorLam the user is able to design a laminate schedule around the specific properties of the craft allowing for a more thorough analysis. and the built-in safety factors make laminate design simple and efficient.
"The ABS (American Bureau of Shipping)" page is very similar to the DNV page. It uses the ABS Guide for Building and Classing High Speed Craft to calculate a bottom pressure based on the specific properties of the craft. This bottom pressure is the foundation of hull laminate design.
