The present invention generally relates to a system and method for using a volatile organic compound (VOC) free low radiant flux LED UV curable composition, and more particularly to unique and novel uses of the composition such as one or two or more of a fire retardant, clear coat, composite material, resin, top coat, improved holdout coating, a sealant coat, and combinations of the same.

Structure intended to stiffen a component made of thermosetting composite material by being fitted to at least one of its surfaces, including: at least one longitudinal body, with first and second longitudinal edge faces on opposite sides, and first and second lateral faces on opposite sides; at least one base including at least one mounting base, each base having a plate and first and second tongues which delimit, with the plate, a housing for at least one body, the first and second tongues extending from a main face of the plate and being pressed respectively against the first and second lateral faces of the body. Each mounting base has a plate which is secured to the first longitudinal edge face of a body and which is intended to be pressed against the surface of the component to be stiffened. Each body and each base are made of thermosetting composite material.

Provided is a filament resin molded article capable of reliably maintaining a shape of a 3D model when a shape memory resin is three-dimensionally formed. With the filament resin molded article, it is possible to form 3D models of various shapes, and to improve a curing speed. The filament resin molded article contains a shape memory resin and an inorganic filler. The inorganic filler is, for example, a glass fiber or a carbon fiber. The filament resin molded article is used for a hot melt lamination type 3D printer. A deformed shape is fixed by deforming a 3D shaped object formed using the filament resin molded article containing the shape memory resin, at a temperature which is equal to or higher than a glass transition temperature (Tg) of the shape memory resin and lower than a melting temperature or a decomposition temperature, and cooling the 3D shaped object to the glass transition temperature or lower while maintaining its shape. An original molded shape is recovered by heating the 3D-shaped object in the temperature which is equal to or higher than a glass transition temperature, and lower than a melting temperature or a decomposition temperature.

The present invention relates to a patient board suitable for supporting a patient during medical imaging, radiotherapy and/or surgery. The board comprises a composite comprising a natural or naturally-derived fibre and a thermoset matrix.

A propeller includes a plurality of blades that extends outward in a radial direction of a rotation central axis relative to the rotation central axis, and includes an end that is located on an opposite side of the rotation central axis. Each of the plurality of blades has a maximum angle of elevation in a position ranging from 30% to 60% with the rotation central axis as a starting point of a radius of a circle that passes through the end of each of the plurality of blades with the rotation central axis as a center, the maximum angle of elevation being a maximum of an angle of elevation in each of the plurality of blades. A change in the angle of elevation in a longitudinal direction of each of the plurality of blades is within 10 degrees per 5% of the radius. A change in the longitudinal direction of a cross-sectional maximum blade thickness is within 20% of a maximum blade thickness of each of the plurality of blades per 5% of the radius, the cross-sectional maximum blade thickness being a maximum blade thickness in a cross section of each of the plurality of blades, the cross section being orthogonal to the longitudinal direction. A change in a chord length of each of the plurality of blades in the longitudinal direction is within 20% of a maximum of the chord length in each of the plurality of blades per 5% of the radius.

A method of forming a barrel portion including obtaining a mandrel shaped to define at least an inner surface of a barrel portion of the bat, wrapping a first plurality of layers of fiber composite material about the mandrel, placing a removable material over a first portion of the first plurality of layers, and wrapping a second plurality of layers of fiber composite material over the removable material and the portion of the first plurality of layers not covered by the removable material for form an assembly.
