Control of Composite Cure Processes

1983
The control of a composite cure process is an attempt to minimize thermal and pressure gradients within a laminate. The sources of these gradients (fabrication support materials, tooling, part geometry) were investigated for process significance. In addition, the concept of using engineering cure behavior transformation diagrams (heat rate and cure ...

Modelling of Thermoset Matrix Composite Curing Process

Key Engineering Materials, 2014
Autoclave curing is a common practice to manufacture high temperature thermoset matrix composites in order to improve the mechanical properties of the final product. The cycle design i.e. the definition and optimization of the temperature-time curve is a key issue for a competitive production. In this paper a very fast and effective procedure, based on

Curing kinetics and curing process of phenolic impregnated carbon ablator

Journal of Applied Polymer Science, 2017
ABSTRACTPhenolic impregnated carbon ablator (PICA), which is composed of the phenolic resin (PR) and carbon fiber, is of particular interest to researchers in the aerospace field. In this work, PICA was prepared by the double‐stage isothermal heating curing.

Thermomechanical analysis of composite plates curing process using ANSYS composite cure simulation

Thermal Science and Engineering Progress, 2019
Process-induced dimensional changes in composite parts has been of great interest for many researchers. The induced residual stresses during curing process while the laminate is in contact with the process tool often lead to shape deformation. This paper

Autoclave curing of thermosetting composites: Process modeling for the cure assembly

International Communications in Heat and Mass Transfer, 1994
Abstract The heat transfer process involved in the autoclave curing of fiber-reinforced thermosetting composites is investigated numerically. In the analysis, the cure assembly is assumed to consist of a tool plate, composite laminate, and bleeder/vacuum bag.

Shrinkage Process with Cure and Bake

Japanese Journal of Applied Physics, 2006
Electron beam (EB) and ultraviolet (UV) have a curing effect on resist patterns. We found that high-temperature baking can shrink patterns cured using EB or vacuum ultraviolet (VUV). Critical dimension (CD) measurements were performed after baking.

Optimizing curing process of graphene oxide/waterborne epoxy blends by curing kinetics simulation considering the coupling of heat conduction and curing reaction

Thermochimica Acta, 2019
Curing kinetics of the waterborne epoxy emulsion (EPWE)/Graphene oxide (GO) system was investigated by non-isothermal differential scanning calorimetry (DSC), which shows an autocatalytic behavior and can be well predicted by model fitting kinetic method.

A procedure for characterizing the curing process of cold recycled bitumen emulsion mixtures

Construction and Building Materials, 2018
Due to the presence of water, emulsion and cement, cold recycled mixtures (CRM) are evolutive materials and thus require a certain curing time to develop their long-term properties. The present study describes a laboratory approach for characterizing the
