Are you looking for round tubes, square tubes, or custom curved tubes? LIJIN produces carbon tubes in series, based on your specifications. We can also provide these tubes with inserts. Custom tubes are possible from +/-100 up to several thousand pieces per year. Interested? Get in touch with us!

We specialize in manufacturing composite products, particularly those made from carbon fibers, to provide optimal solutions through innovative technology and high-quality engineering.

TECHNOLOGY

The stainless steel mandrel is wrapped with various layers of narrow carbon prepreg tape. Various tape widths allow for different angles of fibers. Such wrapped tapes give necessary pressure strength. Between these layers, we place even more layers of longitudinal UD prepregs, which give perfect flexible strength to the finished products. Hi-tech shrink tape caused high pressure on curing materials. Autoclave curing takes 3 hours at a temperature of 140 degrees Celsius. After cooling, the mandrel is removed and the tape is unscrewed.

MATERIALS

All carbon fibres we use in carbon fibre tube production are in prepreg form. Prepreg fibres are those that have been pre-impregnated with a resin system. As matrix, we use epoxy resin with high homogeneous weight. We use different carbon fibre grades for carbon fibre tube production, depending on the desired mechanical properties: T700, IMS65, M40J. We use only high quality epoxy matrix with a Tg under 100 degrees Celsius and a completely transparent look.

INDUSTRY

Production consists of further phases: carbon prepreg appliance, installation and curing. For carbon fibre tube processing, we have a cutting machine, a winding machine and a curing autoclave. During carbon fibre tube production, we carefully monitor all technical parameters. Carbon fibre tubes are a part of a wide composite area.
