Systems and methods for improving adhesion of an insulating foam to a molded polymeric insulating structure through use of ozone gas for functionalization of molded polymeric surfaces of an internal cavity of the insulating structure.

This disclosure provides economical and effective methods and apparatus for repairing scratches and scuffs on refillable bottle surfaces that minimally contaminates the bottle during the refurbishing process. In one aspect, the method comprises the steps of: a) adding at least one fluid into the polymeric packaging material such as a bottle to form at least a partially filled packaging material; and b) applying at least one heat source to an exterior surface of the at least partially filled packaging material to form a repaired polymeric packaging material. Apparatus and recycling systems that incorporate this method are also disclosed.

A pultruded strip (50) of reinforcing material for stacking with one or more similar strips (50) to form a spar cap for a wind turbine blade is disclosed. The pultruded strip comprises a core (56) comprising fibres (58) disposed in a resin matrix (60) and a sacrificial layer (52) at least partially covering one or more surfaces of the core (56). The sacrificial layer (52) is a resin layer defining an adherend surface (62A) of the strip. A pultrusion process for making such a strip (50) comprises drawing resin-coated reinforcing fibres (58) through a pultrusion die (80) in a process direction to form a core (56) of the strip (50) and applying further resin (53) to one or more surfaces of the core (56) to form a sacrificial resin layer (52) defining an adherend surface (62A) of the strip (50).

The invention relates to a method for manufacturing a hoisting rope, comprising the steps of providing a plurality of elongated composite members, which composite members are made of composite material comprising reinforcing fibers in polymer matrix; and arranging the composite members to form an elongated row of parallel composite members, which row has a longitudingal direction, a thickness direction and a width direction, and in which row the composite members are positioned side by side such that they are parallel to each other, and spaced apart from each other in width direction of the row; and directing plasma treatment on the outer surface of the composite members; and embedding the composite members in fluid polymer material; and solidifying the polymer material wherein the composite members are embedded. The invention relates also to a hoisting rope obtained with the method and an elevator comprising the hoisting rope.

Systems and methods for processing additively manufactured objects are described herein. In some embodiments, for example, a system includes a controller configured to provide one or more control signals; a heater coupled to the controller, where the heater comprises one or more heating elements arranged to heat a blasting medium in response to the one or more control signals; a chamber coupled to the controller, where the chamber comprises an agitatable drum shaped to receive a plurality of additively manufactured objects, and to agitate the plurality of additively manufactured objects in response to the one or more control signals; and an applicator coupled to the controller, where the applicator comprises a nozzle operative to direct, in response to the one or more control signals, a plurality of thermally conductive particles in the blasting medium toward the plurality of additively manufactured objects within the agitatable drum.

An object of the present invention is to provide a method of joining resin tubes, in which the degree of freedom of selecting a tube material is large, and further a defect such as stiffness and contraction at joining portions of the tubes is not developed. The method of joining resin tubes according to the present invention is a method of joining resin tubes so that a first tube is joined to a second tube, the first tube and the second tube each being made of synthetic resin, the method comprising: a surface activation step of activating each of a joining region of the first tube and a joining region of the second tube; and an adhesion step of adhering the joining region of the first tube obtained via the surface activation step with the joining region of the second tube obtained via the surface activation step to each other.
