Abstract
Composite laminates are disclosed which are designed to exhibit superior resistance to oil and to heat and which are comprised essentially of two different rubbery layers and a fibrous layer interposed therebetween. One rubber layer is formed from a rubber composition made up of highly hydrogenated acrylonitrile-butadiene rubber, an organic peroxide curing agent and magnesium oxide, and the other from a rubber composition of a rubber other than chlosulfonated polyethylene rubber. The fibrous layer is formed from an organic fiber treated with a dip coating of a specified composition. Also disclosed is a composite hose in which the rubbery layers and fibrous layer are assembled.
