Abstract: 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.

Abstract: Two photoelectric circuit sets each have a light source, two light switches, optical fibers, photoelectric sensor and computer. The light source emits visible light to the first switch, which is continuously deflected and reflected by a torsional micro-mirror. The light respectively irradiates each of the optical fibers in a composite material optical fiber prepreg layer. If the material is normal, the optical fiber is not damaged, the visible light passes through the optical fiber and irradiates the second switch, and is continuously deflected and reflected by a second torsional micro-mirror, the light irradiates the photoelectric sensor. The sensor outputs an electric signal to the computer. If the material is damaged, the optical fiber here is damaged, another corresponding optical fiber path at an intersection point is also damaged without electric signal output. The computer gives breaking position coordinates at the intersection point of two paths of optical fiber arrays.

The base has a positioning step for guidance, the circular sleeve is concentrically installed on the step of the base, and the opening end cover is concentrically installed on the circular sleeve and connects to the base through a reaming hole bolt. A circular plate disposed between the opening end cover and base, and opposite sides of the opening end cover and base are provided with concave platforms. Two semicircular-ring convex platforms of the same diameter are concentrically installed on the concave platforms, the reaming hole bolt is tightened with force, and the circular plate is supported and fixed on the fixture. The circular plate and the semicircular-ring convex platform on the opening end cover and base, are in line contact wherein lines are parallel and concentric having the same radius.

Abstract: An adhesive hook includes a base which has a bottom for fixing, an outer surface, and a hook provided at the outer surface. The bottom of the base is fixed on an external surface by means of an adhesive, and the adhesive is a curable adhesive. The structure of the adhesive hook is simple, and the curing speed of the curable adhesive is fast. After the curing process, the load bearing of the hook is larger than 1 Kg/cm2. Further, the adhesive hook has high cohesion strength after the adhesive is cured, and no remain is pasted on the external surface or the base after the hook is removed. The base can be recoated with new adhesive to reuse, which reduces cost and achieves recycling.

Abstract: A skidproof mat is provided which comprises: a rubber layer having a first major surface and a second major surface being opposite to the first major surface, and a thickness defined between the first and second major surfaces; a base layer; and a protection film covering each of the first and second major surfaces of the rubber layer; wherein the base layer is disposed within the thickness of the rubber layer so that the first and second major surfaces of the rubber layer constitute major outer surfaces of the skidproof mat. The protection film is movable when using. The rubber layer can achieve perfect anti-slip effect. The base layer is positioned in the rubber layer to increase the tenacity so that the skidproof mat is impossible to be deformed and has well ageing resistance.
