A molding process of a co-cured short-fiber resin-based damping composite material and a molding part. Different from a traditional centrifugal processing process of a thin-walled tube of a resin-based composite material, the process uses raw materials including three kinds of materials with different densities and including two kinds of short-fiber epoxy resin with different densities and a damping material. During centrifugal molding, the three kinds of materials are made into fluids to be respectively injected at a uniform speed in three times according to the sizes of the densities. Layering is performed by using different centrifugal forces applied to the three kinds of materials. Co-curing is performed according to a resin curing process after the three kinds of materials are stably distributed, and a tubular thin-walled part of the embedded co-cured short-fiber resin-based damping composite material with a uniform wall thickness is obtained.

A polyethylene composition suitable for rotomolding and comprising a blend of a stabilized polyethylene, and optionally a substantially non-stabilized polyethylene, with a recycled polymer (PCR), is described. By using a PCR with a higher density and lower melt flow as compared to the stabilized polyethylene, a higher portion of the recycled polymer is present on the interior surface f the rotomolded part. Oxidation of the recycled polymer results in formation of oxidized species, such as carbonyl groups, on the interior surface of the part, which along with higher surface roughness enhances adhesion between the interior surface and coatings or fillings, such as polyurethane, used to provide a layer of insulation or improve structural strength or buoyancy.

The present invention discloses an anti-hair loss and hair growth integrated core-shell microneedle patch, comprising a backing and a core-shell microneedle array attached to one side of the backing, the core-shell microneedle array comprises a plurality of microneedles arranged on the backing to form an array, each microneedle comprises a shell substrate material and an internal core, and the shell substrate material is loaded with nano-enzyme for removing excessive active oxygen. The present invention uses an anti-hair loss and hair growth integrated core-shell microneedle patch of the above mentioned structure, wherein the shell substrate material is rapidly degraded after the microneedle patch is applied to the skin, the nano-enzyme loaded by the shell substrate material can be passively released to remove active oxygen and promote angiogenesis in the microenvironment around hair follicles, the internal core of the microneedle is loaded with mesenchymal stem cell-derived exosomes, and the internal exosomes are released and conveyed to hair follicle niches after the shell substrate material is degraded, so that improvement of pigmentation and promotion of hair regrowth are possible.
