Filament Winding FRP Manufacturers in China

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.

Process principle

How the filament winding process works

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.

  1. 01

    Mandrel & liner

    Prepare the mandrel and, where required, build the liner or corrosion barrier.

    Control: Check release, liner continuity, resin identity and thickness.
  2. 02

    Fiber wet-out

    Continuous tows pass through resin or arrive as controlled prepreg/towpreg.

    Control: Monitor tension, resin condition and complete impregnation.
  3. 03

    Programmed winding

    The carriage traverses while the mandrel rotates to lay hoop and helical courses.

    Control: Lock angle, bandwidth, payout, overlaps and layer count.
  4. 04

    Cure

    The wound laminate cures on the mandrel, sometimes with staged heat or post-cure.

    Control: Record thermal cycle and manage exotherm and rotation during gel.
  5. 05

    Release & proof

    Remove or retain the mandrel, trim ends, fit details and perform specified tests.

    Control: Map thickness and complete leak, hydrostatic or structural proof tests.
Material system

What enters the process

1

Barrier or liner

Service-compatible resin, veil and inner laminate protect the structural wall.

2

Structural winding

Glass, carbon or basalt continuous fibers placed at design angles.

3

Matrix

Thermoset or qualified prepreg system selected for fluid, temperature and cure.

4

External layer

UV, abrasion, fire or handling protection as service requires.

Strong process fit
  • FRP pipe and cylindrical tanks
  • Pressure vessels and rocket motor cases
  • Ducts, stacks and repeat hollow shells
Engineering watch-outs
  • Openings, branches and local attachments interrupt the ideal fiber path
  • The external surface is not tool-finished and may require finishing

Critical process controls and evidence

A supplier claim is useful only when the process window is tied to the offered material, tooling, drawing revision and production batch.

StageWhat must be controlledEvidence to request
Design releasePressure, vacuum, axial load, supports, nozzles and design factor.Approved calculation and laminate schedule.
WindingAngle, tension, bandwidth, layer sequence and resin pickup.Program identity, machine log and operator release.
CureGel, exotherm, time-temperature cycle and post-cure.Batch cure chart and resin-system traceability.
Final testDimensions, thickness, joints, leakage and pressure performance.Thickness map, inspection report and witnessed proof test.
Defect diagnosis

Common defects, causes and detection

DEFECT 01

Weeping or leakage

Likely cause: Liner discontinuity, dry fiber, porous joint or damaged barrier.

Detection: Holiday, leak or hydrostatic testing plus liner inspection.

DEFECT 02

Incorrect load response

Likely cause: Wrong winding angle, tension, thickness or layer sequence.

Detection: Program review, thickness map and qualification or proof test.

DEFECT 03

Delamination or waviness

Likely cause: Poor compaction, unstable payout, contamination or cure movement.

Detection: Visual/section review and specified NDT for critical vessels.
