“…In contrast, Hayes et al [18] directly cured the resin by application of an electric current into the part rather than the tool, creating a large number of heating elements throughout the composite structure. These heating elements locally heat the surrounding resin of a 60×25cm part.…”

In this paper, a multi-zone self-heating composite tool is developed to manufacture out-of-autoclave complex and high-quality business jet lower wing stiffened composite panel. Autoclave manufacturing is regarded as a benchmark for manufacturing aerospace-grade composite parts. However, high accruing operational costs limit production rates thereby not being practical for smaller-scale companies. Therefore, significant work towards developing out-of-autoclave manufacturing is underway. In this study, a production line tool is developed with embedded heating fabric that controls temperature at the desired zones, replacing the need for autoclave cure. It investigates and identifies the optimal design parameters of the self-heating setup namely the placement of the heating fabric, zones, thermal management system, temperature distribution, heating rate and thermal performance using a thermal FEA model. The associated thermal characterisation of the tooling material and the part are measured for accurate simulation results. The design developed in this study will be used as production guideline for the actual tool.

In Situ Curing and Out‐of‐Autoclave of Interply Carbon Fiber/Carbon Nanotube Buckypaper Hybrid Composites Using Electrical Current

A new simple out-of-autoclave (OOA) method is introduced in this study. Electrical current is applied to layers of CNT BP to generate heat for curing the hybrid composite. The results indicate that hybrid composites fabricated by this in situ curing method exhibits relatively good mechanical properties and low void content, compared to samples produced by the autoclave process. In addition, finite element analysis demonstrates that the in situ curing of composite can achieve uniform heat distribution and energy efficiency. The proposed in situ curing technique is promising for fabricating high-quality advanced composites with potential for energy and cost savings.

Processing carbon fiber reinforced thermoplastic parts includes heating to form the thermoplastic matrix. The needed heat can be applied externally or internally to the preform. One possibility to generate intrinsic heat involves the use of carbon fibers as a resistive element to induce joule heat. So far, most research efforts have been based on contacting continuous carbon fibers on both ends to melt the thermoplastic matrix of a pre-impregnated preform. The objective of this project is to use a dry hybrid yarn textile in a one-step process to impregnate and rapidly consolidate the dry textile in less than a minute. The desired molding process is based on joule heating of carbon fibers due to an applied current in the transverse fiber direction. This article focuses on the detection of the involved macroscopic parameters. The first composites produced by means of this new method exhibit a high potential with heating times of 15 s, a void fraction below 1%, and flexural properties comparable to the state of the art.
