Liner-Propellant Bond Tests.
Abstract
This report describes a method of determining tensile bond strength and lap shear strength between a liner/insulation material and a propellant composition which is cured to portions of the liner/insulation material. The liner/insulation material is bonded to a propellant composition in a dogbone configuration by positioning a predetermined size of the liner/insulation material in a groove that is constructed in a mold in a transverse direction for a tensile bond strength specimen whereby the propellant is bonded to each side of the exposed liner/insulation material. The lap shear specimen is formed in a mold wherein a predetermined size of the liner/insulation material is longitudinally positioned in a groove that is constructed in a mold. The liner/insulation material is centered with a pair of spacers having about one-half of the length of the liner/insulation material to prevent a cast propellant composition from binding to the portion covered by the spacers but to permit the remaining portion of the liner/insulation material to be embedded and cured in the propellant composition that is cast and cured in the mold.
