Partial curing of thermoset composites
10549489 · 2020-02-04 · ·

Composite laminate structures are produced using partially cured parts. Partial curing of the parts is achieved by applying a catalyst to regions of the parts that are to be fully cured. These regions cure at a lower-than-normal temperature while remaining regions of the part remain uncured, allowing them to be co-bonded or co-cured to other structures.

Modular portable accelerated cure system

A modular accelerated cure system, for which the modules are of a size and weight to each be easily portable by one person, may be configured to fit a variety of parts, e.g., carbon fiber reinforced plastic (CFRP) components, such as found in the manufacture of composite aerospace structures. The system may be used to accelerate the cure of materials that allow elevated temperature cures, e.g., sealants, primers, coatings, paints, adhesives, and protective coatings, by increasing the ambient temperature surrounding a part, or a portion of the part, within each module in a controlled manner. The system is modular in that a number of modules may be fitted together to operate in unison and also may be adapted to fit parts of a variety of contours, shapes, and sizes. Temperature within each module may be controlled using a heat controller that receives a temperature indication from each module.
