Abstract
Improved resistance of fiber filled insulation to erosion from combustion gas flow ina solid propellant rocket motor is produced by orienting the fiber direction of the grain of the fibers in the insulation to a direction in which the direction of the fiber grain is substantially perpendicular to the direction of the flow of combustion gas in the rocket motor. Unvulcanized fiber filled insulation sheet stock is folded and compacted in accordion-like style such that the fiber grain direction is reoriented eassentially 90 degrees in the roll direction of the sheet stock.
