[Object] To provide a building material having excellent durability. [Solution] A building material has a convex part formed on a surface thereof, the convex part including a first lateral surface part and a second lateral surface part corresponding to the first lateral surface part. The building material is formed from a mixture containing a hydraulic material, an admixture, and a plant-based reinforcing material, and the plant-based reinforcing material at least in the convex part is distributed in the mixture with the hydraulic material and the admixture attached to the plant-based reinforcing material. A distribution of the plant-based reinforcing material in the first lateral surface part and a distribution of the plant-based reinforcing material in the second lateral surface part are substantially the same. Desirably, the convex part includes a first edge part that is an edge part of the first lateral surface part and a second edge part that is an edge part of the second lateral surface part and that corresponds to the first edge part, and a distribution of holes formed in the first edge part and a distribution of holes formed in the second edge part are substantially the same.

Multilayer films and adhesive tapes that include such films, wherein the multilayer films include plasticized polyvinyl chloride and optionally one or more fillers.

Class-A components (CAC) include a first and second skin layer each having a polymer matrix and a fiber reinforcing material embedded within the polymer matrix, a third layer disposed between the first and second skin layers and including a third polymer matrix and a filler material interspersed within the third polymer matrix, and a Class-A finish coat applied to the second skin layer. The fiber reinforcing materials include a plurality of substantially aligned carbon fibers and a plurality of low strength regions staggered throughout the carbon fibers. The CAC can be integrated with a rigid vehicle frame. The CAC can be a structural component. The CAC can be a door, a roof panel, or a hood. The CAC can include a layer of woven fibers between the Class-A finish coat and the second skin layer and a portion of the woven fibers can be visible through the Class-A surface layer.

The present disclosure relates to a wood-plastic coated metal composite profile and a production process, and belongs to the technical field of composite profiles. The wood-plastic coated metal composite profile includes a metal core material, a wood-plastic surface layer and an intermediate layer provided between the metal core material and the wood-plastic surface layer. The intermediate layer includes unsaturated carboxylic acid modified polyolefin and thermoplastic polyurethane elastomer, inorganic filler, polyurethane prepolymer. In the present disclosure, an intermediate layer is provided between the wood-plastic surface layer and the metal core material for bonding. The intermediate layer has excellent performance when bonding with the metal, and at the same time, it can blend with the wood-plastic surface layer to a certain extent during co-extrusion. Thereby, a stable structure with core material-intermediate layer-wood-plastic surface layer is formed, and the intermediate layer has good elasticity and impact resistance, and can maintain good bonding under various environments.
