A joined body includes a first member, a second member, and a joining portion disposed therebetween and joining the first member and the second member. The joining portion includes a first joining layer on a side toward the first member and formed of a first joining material, a second joining layer on a side toward the second member and formed of a second joining material, and a metal layer therebetween and having a plurality of holes communicating with one another. The metal layer includes a first-joining-material-impregnated layer on a side toward the first joining layer and in which the plurality of holes are impregnated with the first joining material, a second-joining-material-impregnated layer on a side toward the second joining layer and in which the plurality of holes are impregnated with the second joining material, and an unfilled hole layer therebetween and in which the plurality of holes are void.

A prepreg is described having good handleability and a low resin flow, facilitating the work in the process of a molded body and improving the dimensional accuracy of the molded body, where the prepreg includes a fiber substrate; and a resin layer containing a thermosetting resin composition containing at least components [A] (thermosetting resin) and [B] (curing agent of [A]), stacked on one surface of the fiber substrate, wherein the fiber substrate is impregnated with a part of the thermosetting resin composition of the resin layer, the thermosetting resin composition having a complex viscosity 3*24 at 24 C. of 20,000 to 100,000 Pa.Math.s and a complex viscosity 3*70 at 70 C. of 100 to 5,000 Pa.Math.s, and a volatile amount of the thermosetting resin composition is 1 mass % or less when a total mass of the prepreg is 100 mass %.

A graphic assembly, such as a floor or road surface sign for vehicle traffic and/or pedestrian traveled areas, is provided. The graphic assembly can include a polymeric substrate layer fixed to a fabric layer that is positioned between the polymeric substrate layer and an adhesive layer. Further, the graphic assembly can comprise a top surface that includes a plurality of surface enhancement particles embedded within a particle receptive layer that is adjacent to the polymeric substrate layer. The plurality of surface enhancement particles include reflective particles and anti-skid particles.

The invention relates to a carpet tile or carpet strip for the contract market, in particular office and commercial buildings, comprising a machine-woven carpet having warp and weft yarns, a needled felt, an intermediate layer between the needled felt and the machine-woven fabric, wherein a polyester synthetic latex coating is applied to the back face of the machine-woven fabric, wherein the synthetic latex coating penetrates into the fabric from the back face of the fabric to a depth of at least 30% of a perpendicular distance between the back face and the front face of the fabric. The invention also relates to a process for manufacturing a carpet tile or a carpet strip for the contract market, in particular office and commercial buildings.
