A second side of the adhesion promoting layer disposed towards the substrate has an affinity to bond with the substrate material.

There is provided a skin foam-in-place foamed article comprising a pad (15) and a bag-like outer material (20) covering the pad (15). The outer material (20) has a top layer (21) and a liner layer (22) made of a foamed resin. The liner layer (22) has a closed cell structure. A pad-side skin layer (27a) having a density higher than that of a bulk layer (26) is provided on the liner layer (22), on a side of the pad (15). A corona treatment is applied to the pad-side skin layer (27a).

Systems and methods for making a thermoplastic carbon fiber plate having a plastic overmold. The method includes: heating a mold; inserting a thermoplastic carbon fiber component into a mold; mixing a supercritical fluid with a plastic mixture to infuse bubbles into the plastic mixture and to thereby reduce the density of the plastic mixture that includes a resin and glass fiber; injecting the mixture of the supercritical fluid and the plastic mixture into the mold so that a plastic overmold is formed and bonded to the thermoplastic carbon fiber component; and cooling the thermoplastic carbon fiber component and the plastic overmold. The cooled plastic overmold includes a foam core having a lower density due to the gas bubbles and a skin layer having a higher concentration of the resin than the foam core and a reduced surface roughness due to the heated mold.

Disclosed, among other things, are ways to manufacture layered structures. In one embodiment, a foaming process may produce layered structures in reduced density plastics with or without integral skins. In another embodiment, a foaming process may produce deep draw structures in reduced density plastics with or without integral skins. In yet another embodiment, a foaming process may utilize additives, blends, or fillers, for example. In yet another embodiment, a foaming process may involve saturating a semi-crystalline polymer such as Polylactic Acid (PLA) with high levels of gas, and then heating, which may produce a reduced density plastic having high levels of crystallinity. These processes may be used to generate products with layered structures.

Provided is a partially-cylindrical sliding member including a sliding layer including fibrous particles having an average particle size of 5-25 m dispersed in a synthetic resin at a volume ratio of 10-35% of the sliding layer. The particles having a major axis length 20 m are included at a volume ratio of 10% to total particles. A sliding surface side area is defined from the sliding surface and has a thickness of 25% of a sliding layer thickness T, where the fibrous particles having a major axis length of 20 m have a dispersion index of 1.1-6. An interface side area is defined from the interface and has a thickness of 25% of T, where the dispersion index is 1.1-6. An intermediate area is defined between the both areas, where the dispersion index is 0.1 to less than 1.

A preform includes a plurality of reinforcement fiber layers connected to each other by binder resin, the binder resin containing spacer particles insoluble in the binder resin, the spacer particles accounting for a volume proportion of 10% to 80% in the binder resin present in interlaminar gaps between the reinforcement fiber layers.

A sliding member for a journal bearing is provided. A sliding layer includes fibrous particles dispersed in a synthetic resin, and has a sliding surface side region and an interface side region. The particles have an average particle size D.sub.sur, axi and D.sub.sur, cir respectively in an axial and circumferential cross-section in the sliding surface side region, and D.sub.int, axi and D.sub.int, cir respectively in axial and circumferential cross-sections in the interface side region.
