Method for increasing fiber strength translation in composite pressure vessels using matrix resin formulations containing surface acting agents

摘要

Composite pressure vessels having improved fiber strength translation of the unidirectional, axial, impregnated strand or tow strength delivered in tensile strength of hoop fibers of the composite pressure vessel are obtained by a process in which chemorheologically viscosity tailored matrix resin formulations containing surface-active agents or compounds acting as surface-active agents are employed. The use of chemorheologically viscosity tailored matrix resin formulations containing such agents in such a process also reduces the strength variation of pressure vessels produced from prepreg of the matrix resin formulations containing surface-active agents or compounds acting as surface-active agents.
