Lewcott Corporation, a US supplier of phenolic prepregs, says it has responded to customer requests to retest and qualify its PSR133 phenolic to MIL-DTL-64154, Revision B (which has superseded MIL-R-9299, grade B).

The MIL-DTL-64154, revision B specification covers a fibreglass fabric reinforced phenolic laminate for use in composite armour systems

Samples of Lewcott's PSR133 based prepreg were submitted to an independent test lab which tested and confirmed that the phenolic resin based prepregs conformed to the requirements of MIL-DTL-64154, Revision B.

“We are very proud of the capabilities of our PSR133 Phenolic resin," notes Carl Varnerin, Chief Technical Officer at Lewcott. "Prepregs using this base resin have been used extensively in a wide range of demanding applications including armour/ballistics, carbon/carbon and ablatives, and the aircraft interiors markets for many years. Since we specifically developed our phenolic resin for composite applications, we have the ability to target the properties of our phenolic resin for these end markets.”

Lewcott Corp, located in Millbury, Massachusetts, USA, develops phenolic resins and prepregs for use in the aerospace, military/defence and industrial markets.
