Provided is a composite structure capable of bonding a fabric and a synthetic resin material with good workability without affecting the texture of the fabric and having sufficient load-withstanding performance at a very high temperature. The composite structure comprising a synthetic resin material, a fabric, and a double-sided adhesive tape that is disposed between the synthetic resin material and the fabric and bonds them together, the composite structure having a shear strength at 140° C. 15 mN/mmor more.

Composite structure and double-sided adhesive tape

The present invention aims to provide a resin foam, a resin foam sheet, an adhesive tape, a member for a vehicle, and a member for a building that are capable of exhibiting very high sound insulation properties. Provided is a resin foam having a multitude of cells, the resin foam containing: a thermoplastic resin; and a plasticizer, the resin foam having a minimum loss factor of a primary anti-resonance frequency in the range of 20&#xb0; C. to 60&#xb0; C. of 0.05 or higher and a secondary anti-resonance frequency in the range of 20&#xb0; C. to 60&#xb0; C. of 300 to 800 Hz as measured by mechanical impedance measurement (MIM) in conformity with JIS G0602.

Resin foam, resin foam sheet, adhesive tape, vehicle member, and building member

The present invention aims to provide a flexible resin foam having excellent shapeability and a resin foam sheet, an adhesive tape, a member for a vehicle, and a member for a building each including the resin foam. Provided is a resin foam having a multitude of cells, the resin foam including: a polyvinyl acetal; and a plasticizer, the resin foam having an elongation strain of 300% or more and a 50% compression stress of 70 kPa or less.
