ABSTRACT:
The blade for a table tennis bat includes a layer of lightweight, low modulus of elasticity material positioned centrally with respect to the thickness of the blade and overlaid by a constraining layer of high modulus of elasticity material. The blade also includes a smooth, rigid outer layer bonded to the outer surfaces of the two constraining layers. The constraining layers are composed of strands of stretch resistant material woven transversely to each other to form a thin mat.
