vespel® cp-j9九游会老哥论坛

v-grooves in jet engine designs create an air seal between the engine fan case and the nacelle. v-grooves are commonly made from coated aluminum, which can corrode and suffer damage during prolonged use, resulting in poor sealing and air leakage. 

v-groove wear strips made with vespel^® cp-0664 composite offer a durable, low-friction and wear-resistant alternative to coated aluminum in v-groove applications. vespel^® cp-0664 has a demonstrated ability to protect larger engine components and fan cases from damage that can require costly repairs and removal of engines from service.

application

jet engine designs utilize v-grooves to create air seals between the engine fan case and nacelle. v-grooves need to be durable to withstand corrosion and multiple impacts over the life of the engine.

challenges

• major seal components are typically coated aluminum.
• coatings have to hold up to repeated impacts to avoid damage to primary metal.
• v-grooves must be treated to prevent corrosion from exposure to weather and operational environments.
• components must be easily maintained in the field to maximize service time.

solution

• vespel^® cp-0664 is a unique composite fabric coating used in a variety of aerospace applications up to 400^°f/205^°c.
• material can be pre-formed to required geometries for bonding to critical surfaces.
• fabric provides low friction and durable coating to aluminum surfaces while creating a corrosion barrier.

features and benefits

• wear resistance
  vespel^® cp-0664 has seen extensive use in jet engine fans and nacelles and proven itself with years of service. wear testing has been conducted over a variety of test conditions and proven to survive from 7,500 to over 250,000 cycles. a transfer film is created on the mating metal surface which minimizes the wear on both the metal and composite surfaces.
