Abstract
Abstract A process for manufacturing a composite panel capable of shock absorption comprising applying a bonding agent with an added cross-linking agent on a surface of a foam member to form a primer treatment surface thereon and applying to a surface of a laminating member the same or a similar bonding agent with added cross-linking agent. The treated surfaces of the foam member and laminating member are then placed into contact with one another and the two members are bonded together while heating the same and applying pressure thereto.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
103 words
A process of manufacturing a composite panel capable of shock absorption, said process comprising subjecting a surface of a polyolefin foam member to a primer treatment in which a polyester hot-melting bonding agent with an added isocyanate cross-linking agent is applied to said surface and is hardened by cross-linking thereof to form a primer treatment surface having no hot-melting adhesive properties, applying to one surface of a laminating member a cross-linking type hot-melting bonding agent, placing the treated surfaces of the foam member and laminating member in contact with one another, and bonding the two members together while treating and applying pressure thereto.
