碳纤维层压板

Photographs from our production. Surface finish and shade vary slightly between batches.

买家为何找我们做层压板。 A laminate is where fabric, resin and process have to agree at once. Buyers usually arrive with a part that has already failed somewhere — a panel that warped after machining, a plate that delaminated at the edge, or a surface that looked right until it was polished. This page sets out what we press, what we control, and what you should specify before tooling is cut.

Pressed laminate sheets and plates, 1.0–3.0 mm, full carbon and carbon/glass hybrid.

What we press

Carbon fiber laminates are made by impregnating carbon fabric or unidirectional reinforcement with resin, then consolidating under heat and pressure in a matched mould. We press to specification, which means thickness, resin content and surface finish are set by our process rather than negotiated with a third party.

Why thickness tolerance is the number to argue about

Most laminate complaints we see are not about strength. They are about thickness.

A laminate is pressed to a nominal thickness, but the achieved thickness depends on fibre areal weight, resin content, ply count and mould closure. Two consequences matter commercially:

1. 1.0 mm 板材上 ±0.1 mm 的偏差就相当于 10%。 If your assembly has a fixed slot, that band may be the difference between fitting and rework. Specify the tolerance you actually need, not a round number.
2. 机加工会暴露材料内部。 Drilling and edge trimming cut through plies, and a poorly consolidated interior shows up as fuzzing or delamination at the cut edge. If the part will be machined, tell us at quotation stage — we press and cure with that in mind rather than treating it as a finishing operation.

层压板买家应明确的事项

Before we quote, these five items decide the price and the outcome:

• 载荷工况 — bending, in-plane tension, or a cosmetic panel with no structural duty. This decides UD versus woven, and whether a hybrid can replace full carbon.
• 厚度与公差 ——公称值加上您可接受的偏差带。
• 树脂体系 — epoxy unless there is chemical exposure, in which case vinyl ester.
• Surface requirement — visible weave under clear coat, painted, or purely functional. Cosmetic faces consume more time than structural ones.
• Post-processing — waterjet, CNC routing, drilling, edge chamfering. Machining a pressed sheet is not the same as pressing a near-net shape.

Sending a drawing is faster than sending a description. If the part already exists in another material, tell us what it is and what failed — that is usually the most useful single piece of information in the enquiry.

应用领域

Carbon fiber laminates are specified where stiffness, weight and dimensional stability matter at the same time:

• 无人机机体 — arms, plates and mounting decks machined from pressed sheet
• 工业机械部件 — wear plates, guides and lightweight structural panels
• Sports equipment — skateboard decks, plate inserts, protective shells
• 汽车与摩托车 — interior trim panels, brackets and stiffening plates
• Marine — hatches, backing plates and reinforcement panels
• 电子与仪器 — housings, base plates and EMI-related structural parts
• 建筑加固 — UD plate for beam and slab strengthening

Supply regions

我们供应层压板给 欧洲 和 东南亚, with Vietnam as a key market for both finished plates and cut-to-size parts. For Vietnam and neighbouring markets we routinely quote cut-to-drawing rather than full sheets, because local machining capacity varies and shipping a finished part is often cheaper than shipping a sheet and machining it twice.

Documentation supplied with export orders: certificate of origin, packing list, commercial invoice, and mill or batch test reports for the grades and tests we hold.
