Multilayer composite interior component

A laminated composite interior component, having cushioning property, including a first member having a predetermined mating surface, and a second member made of an elastically deformable resin material, having a plate portion on and parallel to the mating surface and multiple solid protrusions formed integrally with the plate portion and having tip ends that protrude toward and contact the mating surface, and flexural rigidity of each protrusion against a compressive load having anisotropy around an axis perpendicular to the plate portion. Each of the protrusions have a longitudinal shape in a transverse section parallel to the plate portion and have one or more stepped portions, with a smaller section at its tip end side, in one of a pair of sidewalls located in a lateral direction perpendicular to a longitudinal direction of the longitudinal shape. Each protrusion is tilted toward a sidewall opposite the stepped portion.

Pneumatic fender
11486108 · 2022-11-01 · ·

Reinforcing layers each have a cord angle set to 25° or greater and 45° or less when a body is in a neutral state. When the body is loaded with a specified internal pressure, intermediate rubber layers disposed between adjacent sets in which cords of the reinforcing layers extend in an intersecting direction are shear-deformed, the cord angle increases approximately to a stable angle of repose, and the expanded body maintains a predetermined shape. In each of the sets being formed of two reinforcing layers layered adjacently, the cords of the reinforcing layers extend in an identical direction at the predetermined cord angle. Since substantially no shear force acts on the intermediate rubber layers disposed between the reinforcing layers, the resistance when expanding the body decreases. This provides a pneumatic fender that expands more smoothly and ensures a predetermined shape when a body is loaded with a specified internal pressure.

Method and system for forming a self-sealing volume using a breather system

A fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.
