Source glass, carbon, basalt and aramid reinforcement from China suppliers by fibre type, sizing, product form, application and traceable evidence.
| Field | Typical range | Sourcing note |
|---|---|---|
| Fibre | E / ECR / S glass, carbon, basalt, aramid | State performance class and chemistry. |
| Form | Roving / chopped / mat / fabric / veil / prepreg | Match the downstream process. |
| Sizing | Process- and resin-compatible systems | Request compatibility and reference applications. |
| Key controls | Tex / tow / filament / areal weight / moisture | Define tolerance and sampling. |
| Packaging | Palletised bobbins, rolls or sealed bags | Control moisture, splice and handling damage. |
| Approval | CoA review + line trial + laminate test | Do not approve on datasheet alone. |
China is a major production base for glass-fibre rovings, chopped strand, mats and fabrics, as well as carbon, basalt and other high-performance reinforcements. A generic fibre designation is insufficient for composite processing. The sizing must be compatible with the resin and process, while tex, filament diameter, tow size, areal weight, weave, moisture and package format affect handling and laminate quality.
Pultrusion, winding, spray-up, SMC, thermoplastic compounding and infusion need different product forms and sizing behaviour. Buyers should provide the resin, process, line speed or flow need, target properties and existing reference grade. For carbon fibre, define tow size, strength and modulus class, surface treatment and test basis. For fabrics and mats, include areal-weight tolerance, width, roll length, splice policy and packaging.
getfrp screens verified producers and converters by fibre family, form, application, scale and export readiness. The matching process can include direct producers and specialised fabric or mat converters, but their roles are distinguished. Before approval, compare a current certificate of analysis and run process trials; a nominally equivalent roving can change wet-out, fuzz, breakage, resin demand and final performance when sizing or package construction differs.
Every card is an explicit supplier-product relationship. Verification applies to the recorded capability and evidence state, not a blanket certification of every specification.

ECR glass is formulated for improved corrosion resistance compared with conventional E-glass and is widely considered for aggressive environments. Actual performance still depends on fibre, sizing, resin and laminate quality. Ask for the offered grade’s chemistry and application evidence.
Sizing protects the fibre during handling and controls compatibility with resin and process. It affects wet-out, adhesion, fuzz, breakage and final properties. A roving with the same tex but a different sizing may behave very differently on a pultrusion or winding line.
Compare tow size, tensile strength, modulus, elongation, density, sizing level, surface treatment, test method and statistical basis. Confirm whether values apply to fibre, impregnated strand or laminate. Process trials are essential when changing an established grade.
Verify labels and batch traceability, package condition, mass, tex or areal weight, width, moisture where relevant and a current certificate of analysis. For a new source, add handling and laminate tests tied to the downstream process and approved reference material.
