✦ Synopsis

Leather / polymer composites were prepared by impregnating chrometanned cattlehide with a solution containing 1,1 -( methylenedi-4,1-phenylene ) bismaleimide and Jeffamine D-230. The mechanical properties in tension, glass transition temperatures, dynamic storage moduli, and moisture absorption of the composites were measured. Impregnated samples showed significant changes in tensile properties, such as the Young's modulus and strain at break, when compared with chrometanned cattlehide. In addition, impact energy increased significantly upon formation of the leather / polymer composite over that of the bismaleimide -Jeffamine resin itself.
