MIL-C-882 Fabreeka Pad as Vibration Isolation
Fabreeka pad is the original fabric reinforced, elastomeric pad developed in 1936. The Fabreeka pad conforms to the specifications for MIL-C-882 cotton duck, fabric reinforced pad. The properties of the Fabreeka pad are exceptionally suited for vibration isolation and structure-borne noise reduction.
Fabreeka pad has been used for over 70 years for mounting machinery and equipment where absorption of impact shock and isolation of transmitted vibration is desired. Fabreeka pad is also used to provide structural damping and to break the vibration transmission path. Fabreeka pad is scientifically constructed to give years of service under the most severe operating conditions.
Associated Applications:
Industrial Machinery
Military/Defense
Petroleum/Gas
Power Generation
Rotating/Vibrating Equipment
Key Features/Benefits:
- Depending upon the size and thickness, Fabreeka pad can ultimately withstand loads up to 12,000 psi. Normally, compressive stresses are designed not to exceed 2,000 psi to extend service life and reduce permanent set.
- Fabreeka pad has a relatively high damping rate of 14% of critical, twice the value of damping for natural rubber and unreinforced elastomers.
- Natural Frequency as low as 12 Hz.
Technical Specifications:
One of the advantages of the reinforced, laminated design is the reduction of additional deflection due to creep under static load. Creep is limited to approximately 5% of the original pad thickness. When stresses are removed, the permanent set is also limited to approximately 5%.
Fabreeka pad meets or exceeds the MIL-C-882 and MIL-E-5272 military specifications.
Fabreeka pad is impervious to most oils and is resistant to the effects of steam, water, mildew and brine. The effective temperature range is -65°F to 200°F.
The durometer of the Fabreeka pad is 90±5 (Shore A).
