The invention relates to a reinforcement member comprising a heatcurable structural adhesive on a carrier member, wherein the carrier member comprises a fiber-reinforced polyester material. The invention further relates to a method to produce such a reinforcement member and its use.

An adhesive sheet expandable by heating is provided. The adhesive sheet, before expansion, achieve temporary fixability at room temperature and ease of insertion when inserting one member into a cavity of another member. The adhesive sheet, after expansion, maintains excellent adhesive strength to enable the members to be firmly bonded together even under high temperature environments. An adhesive sheet includes a first principal face and a second principal face opposite to each other. The first principal face includes a thermally expandable thermosetting adhesive layer and a plurality of sticky parts provided on a first principal face of the thermally expandable thermosetting adhesive layer in a patterned manner. The second principal face includes the thermally expandable thermosetting adhesive layer forming the first principal face of the adhesive sheet or another thermally expandable thermosetting adhesive layer. An article including the adhesive sheet, and a method for producing the same are also provided.

An adhesive sheet includes a first face and a second face opposite to each other. The first face includes a thermally expandable thermosetting adhesive layer A, and the second face includes a thermally expandable thermosetting adhesive layer B having a different composition from that of the thermally expandable thermosetting adhesive layer A. The thermally expandable thermosetting adhesive layer B is laminated on one face of the thermally expandable thermosetting adhesive layer A directly or through another layer. The first face has a higher shear adhesive strength than a shear adhesive strength of the second face. The thermally expandable thermosetting adhesive layer A and the thermally expandable thermosetting adhesive layer B each have a thickness direction expansion rate after heating at 150° C. for 60 minutes of 130% or more.

A method for dielectrically heating foamable composition to foam and set the composition is described. In particular, radio frequency (RF) heating is used to heat the foamable composition to provide insulation in the manufacture of an article.
