Aircraft Composites Manufacturing

CHANGWEI PTFE coated fiberglass fabric with or without adhesive are used in the manufacturing of aircraft composited components, such as helicopter rotor blades, satcom and weather radomes, structural component like tail sections, wings and wire harness protective insulation.

In the full range of applications, the release properties, mechanical properties and porosity of the product selected are critical to the performance of the manufacturing process and the quality of the products produced.

 

Vacuum Bagging Bleeder Cloths

Vacuum Bagging Bleeder Cloths, make of PTFE coated fiberglass fabric with low level of PTFE content, which has a higher porosity than normal PTFE coated fabric. In this case, air and extra resin will be allowed for passing through the bleeder cloths. This fabric is used as release sheet and bleeder cloth, for the manufacturing of aircraft composites, including satcom and weather radomes, helicopter rotor blade, structural components like wings, tail section, fuselage component and so on.

The request for PTFE bleeder cloth is as follows

• Clean release property
• Controlled porosity
• High mechanical strength

 

PTFE Mold Release Tape

PTFE Mold Release Tape, make of woven fiberglass coated with high quality PTFE(TEFLON), and back side coated with Silicone PSA. This mold release tape has higher tensile strength than normal self adhesive PTFE fabric. In this case, CHANGWEI adhesive tape will be easily took down after repeatedly used.

CHANGWEI mold release adhesive fabric is used to stick the molding, for the manufacturing of aircraft composites, wind power blade composite, like satcom and weather radomes, helicopter rotor blade, structural components like wings, tail section, fuselage component and so on.

The request for PTFE mold release tape is as follows,

• Outstanding easy release property
• Low adhesion, easy to peel
• Excellent mechanical strength, can be reusable
• No adhesive left after peeled.

Aircraft composites manufacturing

PTFE coated fiberglass fabric is widely used in various aircraft composite manufacturing process, including vacuum bagging technique, open molded and hand lay-up process.

PTFE bleeder cloth and PTFE mold release tape will be used directly to the mold and product, allowing for a easy and clean release after the curing process of aircraft composite. CHANGWEI porous PTFE fabric can ensure perfect release while maintaining the breathable property, which can allow air and volatiles to escape during production. And due to the high mechanical strength of mold release tape, CHANGWEI adhesive fabric is reusable and provide clean release.

The applications including helicopter rotor blades, satcom, weather radomes and others.
