A size of a width of the tape-like member constituting the fiber-reinforced resin layer is not less than 100 times and not more than 400 times as large as a size of a thickness of the tape-like member constituting the fiber-reinforced resin layer in the radial direction.

In a preferred embodiment, a composite panel with a smooth outer surface, ready for painting with or without addition of primer, may be created by constructing a panel layup assembly upon a mold, the panel layup assembly including a composite panel having a core and a resin formulation, and a release film between the mold and the composite panel, where a smooth release surface of the release film is in contact with the composite panel upon construction; initiating curing of the composite panel at a first temperature within a lowermost ten percent of a curing temperature range of the resin formulation; continuing curing of the composite panel at a second temperature above the lowermost ten percent of the curing temperature range; and completing curing of the composite panel at a third temperature below the second temperature.

A laminate substrate for receiving a semiconductor chip. Included are laminate layers stacked to form the laminate substrate, each laminate layer includes a core that includes particle-filled epoxy and a metallic layer on the core. At least one laminate layer has a radial cut through the metallic layer, the radial cut extending from a periphery of the at least one laminate layer towards a center of the at least one laminate layer. The radial cut cuts only through the metallic layer and does not cut through the core.

Bio-inspired carbon fiber reinforced polymer (CFRP) composite laminates are provided. The CFRP laminates display high out-of-plane strength and ductility due to the incorporation of defects (e.g. areas of delamination) which are purposefully introduced into the laminate layers.
