摘要： A process for producing a partially balanced acid solution that involves metering dicarboxylic acid powder, based on weight, from a loss-in-weight feeder to a feeding conduit that transfers the dicarboxylic acid powder at a low variability feed rate into an in-line disperser, adding a first feed stream of diamine to the in-line disperser in an amount sufficient to form the partially balanced acid solution having a solids content of less than 60%, and storing the partially balanced acid solution at a temperature to maintain the dissolved dicarboxylic acid and to prevent formation of a slurry. The partially balanced acid solution may be used as a feed solution to prepare a nylon salt solution. Process controls for the process are also disclosed.

摘要： A method of monitoring the evolution of polymer and/or colloid stimuli responsiveness during synthesis of polymers and/or colloids, including postpolymerization modifications on natural and synthetic polymers, includes providing a reactor in which the polymers and/or colloids are synthesized; and providing a means of monitoring the stimuli responsiveness of the polymers and/or colloids during said synthesis. Preferably, the method also includes monitoring the evolution of the characteristics of the polymers and/or colloids during said synthesis. Preferably, evolution of polymer and/or colloid stimuli responsiveness is correlated to the evolution of the properties of the polymers and/or colloids themselves. Also, preferably the conditions of the fluid in the reactor in which the synthesis occurs is determined. The determination can be by detection, choice of materials and temperature conditions, for example, and combinations thereof. The method and instrumentation disclosed can lead to optimization and control of processes and synthetic and modification strategies leading to polymers and colloids with desired stimuli responsiveness.

摘要： Test liquid (3) including thermosetting resin is injected from an injection valve (2). Light (L) is irradiated to a spray (6) of the test liquid (3) injected from the injection valve (2) as a treatment for producing a hardening effect to the thermosetting resin. Liquid drops in the spray (6) are hardened and collected as particles. Spray characteristics such as a particle size distribution of the injection valve or the like are analyzed by using the collected particles.

摘要： The present application relates to a method and system for optimizing a composite system by electrically monitoring the reactive and physiological behavior of the resin binder in a composite system, so as to develop the desired properties of the resin during the cure process. A method of manufacturing a composite part can include assembling a composite preform with a resinous material and an open circuit. Further, the method can include subjecting the composite preform to a curing cycle so that a resin in the resinous material melts and closes the open circuit. Further, the method can include electrically monitoring a current through the resin during the curing cycle. Further, the method can include selectively controlling a manufacturing variable in response to the step of electrically monitoring the current through the resin.

摘要： Improved methods of detecting thermal exposure are provided herein. The provided methods utilize initially dormant luminescent probes incorporated into a matrix to form a composite. When exposed to heat over a period of time, the luminescent probes are “activated” through a molecular transformation initiated by thermal energy. The activated probes exhibit a luminescent profile based on the extent of thermal exposure, thereby providing an indicator of the thermal exposure experienced by the matrix. When the composite is used to produce a structural component of a vehicle (e.g., an aircraft), the methods provide a convenient, large-area indicator of thermal damage experienced by the structural component.
