FRP calculators, references, and production tools
Engineering tools for composite manufacturers who need answers fast.
Welcome to the world of composites. Composite Desk helps FRP manufacturers, engineers, estimators, and production teams calculate laminate weight, resin consumption, costs, quotations, and factory planning inputs from one practical online workspace.
Built by FRP technical experts and software engineers for teams working with panels, tanks, covers, interiors, marine parts, industrial components, and custom composite products.

Basic calculators
Start with the calculations every FRP job needs first.
Use the Basic calculators to check panel weight, resin/fibre consumption, and glass/resin weight before purchasing material, preparing a quote, or planning a production batch.
For estimators
Get quick material quantities before quoting a new part or checking whether a customer drawing has enough information.
For production teams
Convert laminate assumptions into Realtime data such as Resin consumption, Reinforcements required etc. which can be discussed with the Process staff in the shop floor.
For owners and managers
Move toward a repeatable costing workflow instead of rebuilding the same estimate for every inquiry.
For engineers
Keep assumptions visible so calculations can be reviewed, explained, and improved as the Pro library expands.
Why teams come back
Composite work needs more than one-off calculators.
FRP teams can estimate, diagnose defects, Prepare quotes and plan production processes instead of referring several documents and supplier data sheets.
Estimate material requirements
Calculate laminate weight, resin quantity, fibre demand, core mass, consumables, waste allowance, and material take-off inputs.
Understand material choices
Build toward clear references for glass, carbon, aramid, basalt, resins, cores, densities, process compatibility, and practical applications.
Prepare better quotations
Turn quantities, labour, machine time, overhead, tooling allocation, and margin into a more consistent cost sheet and quotation process.
Diagnose manufacturing issues
Connect defects such as air bubbles, dry spots, delamination, warpage, cracks, pinholes, and blisters to root causes and corrective action.
Plan production capacity
Use cycle-time, labour, oven, shift, and factory overhead workflows to understand whether a job can be produced profitably and on time.
Standardize team knowledge
Collect process guidance, design notes, standards, checklists, SOPs, and downloadable templates in one reference point for the team.
Materials
Compare the material families behind every FRP decision.
Review reinforcement, resin, and core information in a practical structure that helps engineers and estimators move from material quantities to material selection.

Design Tools
Move from estimates into preliminary design checks.
Pro design tools help users structure early engineering decisions for laminate design, sandwich panels, core selection, and panel deflection before formal validation and certification.
Laminate Design
Preliminary ply count, layup recommendation, orientation distribution, laminate thickness, and tensile stress screening.
Open calculator hubSandwich Panel
Skin/core weight, areal weight, simplified bending stiffness, shear stiffness, pressure load, and first-pass checks.
Open calculator hubCore Selection
Compare candidate cores by deflection, shear, face stress, core crushing, weight, and selection priority.
Open calculator hubPanel Deflection
Check solid FRP panel deflection under uniform loading against application-based allowable deflection limits.

Tools for railway FRP panels and interior components.
Railway composite teams need practical estimates for panel weight, resin consumption, core choices, stiffness checks, production time, and cost inputs. Composite Desk helps organize those early decisions before a project moves into detailed engineering, testing, and approval.
