The present invention relates to a structure for preventing the adhesion of microorganisms, which is capable of preventing microorganisms from adhering to and growing on a surface of an object, and a method of manufacturing the same. The structure for preventing the adhesion of microorganisms includes: a nano-structure configured to include a plurality of protruding structures each having a sharp end, and made of a resin composition; and a plurality of nano-metal particles configured to be distributed inside the nano-structure. A method of manufacturing a structure for preventing adhesion of microorganisms includes preparing a liquid resin; mixing the liquid resin with nano-metal particles; depositing the liquid resin on a substrate; pressing the liquid resin with a master template on which a pattern corresponding to a plurality of protruding structures is formed; and setting or curing the liquid resin.

A compression moulding tool for manufacturing a fibrous pulp tray having a floor portion and walls extending from the floor portion. The tool comprises a first female mould element comprising a plurality of first recessed portions, a water permeable filter arranged in the first female mould element and configured to follow the surface of the female mould element, a second female mould element comprising a plurality of second recessed portions at locations corresponding to the first recessed portions and smaller than the first recessed portions, and a male mould element configured to press against the first and second female mould elements to compress a fibrous pulp product located therebetween, the male mould element having a surface profile free from macroscopic features at locations corresponding to the first and second recessed portions of the first and second female mould.

A lens sheet includes a base made of transparent resin, a lens part formed on the base and having a convex lens, and a protrusion formed around the lens and having a height lower than a height of the lens. A gap is provided between the lens and the protrusion.

A method for making a yoga towel includes a step of preparing a towel with multiple apertures defined therethrough, a resilient plate placed on the towel; a step of placing the towel and the resilient plate between a top mold and a bottom mold which has cavities defined therethrough; a step of heating and softening the resilient plate and matching the top mold to the bottom mold, and a step of vacuuming to suck the softened resilient plate to form anti-slip protrusions on the second face of the towel via the apertures. The anti-slip protrusions are integrally formed with the towel and have elasticity.

A sandwich structure which is configured of skin layers each including at least one layer selected from among a metal layer, a fiber-reinforced resin layer (X) that includes continuous fibers and a matrix resin (A), and a fiber-reinforced resin layer (Y) that includes discontinuous fibers and a heat-curable matrix resin (B) and of a core layer including a flowable core layer that includes discontinuous fibers and a matrix resin (C), wherein the skin layers are constituted of a material which has a flexural modulus higher than that of the core layer, and a through part has been formed in a region that lies in at least some of the skin layers. In the sandwich structure, an upright part which projects in an out-of-plane direction of skin layer and which has high strength and a complicated shape such as a rib is obtained by an easy method.

A method may comprise: laying up a first plurality of plies of material comprising thermoplastic resin and fiber to form an inner skin preform, the inner skin preform being a continuous sheet including alternating peaks and valleys; laying up a second plurality of plies of material comprising thermoplastic resin and fiber to form an outer skin preform; and joining the inner skin preform to the outer skin preform.

A spinner for a fan assembly of a gas turbine engine, a method of fabricating a spinner for a fan assembly of a gas turbine engine, and a gas turbine engine are disclosed. The fan section may include a nosecap. The spinner may include a forward end, an aft end, and a return flange associated with the forward end. The return flange may include a forward flange extending forward towards the nosecap and an aft flange extending aft towards the aft end.

Provided is a mold for manufacturing a skin attachable thin film, the mold including: a cast part having a U shape to accommodate a mixed solution in an inner space, and including a lower surface part and a side part, and an inner space accommodating the mixed solution; and at least one protruding pillar protruding from at least a partial region of the lower surface part.

This invention relates to a moulding compound blank, a method for compression moulding the same and the resulting product. The blank comprises a moulding compound comprising a fibrous reinforcement material and a resin material wherein the moulding compound comprises a flow guide (6, 7, 8) located at the surface of the blank for directing flow of the moulding compound within the cavity of the compression mould during compression moulding.

A molding provided with a sheet-shaped composite material section formed from a fiber-reinforced composite material containing reinforcing fibers and a matrix resin, and protruding ribs formed directly on a first surface of the composite material section and containing a thermoplastic resin, wherein the ribs intersect with each other on the first surface, and the mean width t, mean height H and the proportion occupied on the first surface are within specified ranges. A manufacturing method for the molding including a composite material section-forming step for forming the composite material section, and a rib-forming step for forming the ribs so as to satisfy the above conditions.
