Barrier or liner
Service-compatible resin, veil and inner laminate protect the structural wall.
Filament winding places resin-wet or prepreg continuous fibers over a rotating mandrel at programmed hoop and helical angles. The process is suited to pipe, tanks and pressure-bearing shells because fiber orientation can be matched to circumferential and axial loads.
Mandrel rotation and carriage travel define the winding path. Tension, bandwidth, angle, layer sequence and cure must stay tied to the design calculation and liner or corrosion-barrier specification.
Prepare the mandrel and, where required, build the liner or corrosion barrier.
Continuous tows pass through resin or arrive as controlled prepreg/towpreg.
The carriage traverses while the mandrel rotates to lay hoop and helical courses.
The wound laminate cures on the mandrel, sometimes with staged heat or post-cure.
Remove or retain the mandrel, trim ends, fit details and perform specified tests.
Service-compatible resin, veil and inner laminate protect the structural wall.
Glass, carbon or basalt continuous fibers placed at design angles.
Thermoset or qualified prepreg system selected for fluid, temperature and cure.
UV, abrasion, fire or handling protection as service requires.
A supplier claim is useful only when the process window is tied to the offered material, tooling, drawing revision and production batch.
| Stage | What must be controlled | Evidence to request |
|---|---|---|
| Design release | Pressure, vacuum, axial load, supports, nozzles and design factor. | Approved calculation and laminate schedule. |
| Winding | Angle, tension, bandwidth, layer sequence and resin pickup. | Program identity, machine log and operator release. |
| Cure | Gel, exotherm, time-temperature cycle and post-cure. | Batch cure chart and resin-system traceability. |
| Final test | Dimensions, thickness, joints, leakage and pressure performance. | Thickness map, inspection report and witnessed proof test. |
Likely cause: Liner discontinuity, dry fiber, porous joint or damaged barrier.
Detection: Holiday, leak or hydrostatic testing plus liner inspection.
Likely cause: Wrong winding angle, tension, thickness or layer sequence.
Detection: Program review, thickness map and qualification or proof test.
Likely cause: Poor compaction, unstable payout, contamination or cure movement.
Detection: Visual/section review and specified NDT for critical vessels.

Fiber angle sets how much reinforcement resists hoop, axial and combined loads. The approved winding program is therefore part of the engineering definition, not an interchangeable factory setting.
Request the design basis, liner and structural laminate schedule, material lots, winding program identity, thickness checks, cure record, joint procedure and specified leak or pressure-test report.
No. Wet winding is common, but towpreg and thermoplastic routes also exist. The impregnation and consolidation method must be qualified for the chosen fiber-matrix system.
Send one controlled specification. GetFRP checks the matching public network without inventing supply records.
