A method of manufacturing a molded solid surface includes mixing ferrous particles into a resinous material, injecting the resinous material including the ferrous particles into a mold, the mold including an upper mold half and a lower mold half, creating a predetermined pattern in the resinous material by applying a force to the ferrous particles in the resinous material toward a surface of the upper mold half or the lower mold half using one or more magnets, and curing the resinous material in the mold into the molded solid surface.

A patterned surface structure formed from a ferrofluidic polymer resin having a plurality of magnetic nanoparticles. The polymer resin is patterned with a magnetic field that is applied to the ferrofluidic polymer resin during curing. The ferrofluidic polymer resin may be cast over a non-magnetic planar substrate. A magnetic field is applied to the ferrofluidic polymer resin to induce a pattern in a surface of the ferrofluidic polymer resin. The patterned ferrofluidic polymer resin is then cured to form the permanently patterned surface.

The present invention addressed the problem of providing a molded body which has a high performance of reducing energy caused by the application of a load, and which is obtained from a fiber-reinforced resin containing reinforcing fibers arranged while aligned in one direction. To solve the problem, the present invention relates to a molded body, including a reinforced layer formed by layering fiber-reinforced resin layers containing a plurality of reinforcing fibers arranged while aligned in one direction and a matrix resin impregnated with the reinforcing fibers. In the molded body, the reinforced layer has a plurality of alignment shifted layers, which are fiber-reinforced resin layers in which the shift angle, i.e., the angle formed by the reinforcing fibers with respect to the longitudinal direction of the reinforced layer, is 25 to 65 or 65 to 25.
