Adhesive Testing Chamber Design for Optimizing Acoustic Honeycomb Core Composite Panels
MetadataShow full item record
Composite honeycomb core sandwich panel structures that require acoustic dampening properties have an adhesive layer reticulated during panel manufacturing. Depending on core and adhesive material types, application of different optimal parameter values for reticulation including air temperature, flow rate, and exposure time are required. The objective of this report is to address Cormer Aerospace’s need for a reticulation test cell to determine these values. The implementation of the presented design will aid in identifying optimal reticulation production parameters. Presented in this report is a standalone semi-automated reticulation test cell, which is comprised of three main modules. These modules include an oven chamber with drawer action, an air knife module, and a gantry module. The combined use of these modules allows application of reticulation parameters in a uniform, controlled, repeatable, semi-automated manner to address the client needs. Controls of adjustable processing parameters including temperature, airflow rate, and exposure time of the honeycomb-adhesive system allow the client to utilize the test cell in a research and development environment. To aid the client in procurement and assembly of the proposed design, a bill of materials, build drawings for installation instruction, and an itemized cost estimate are communicated, as well as analyses that ensure effective use. The proposed test cell costs $11,125.16 CAD to procure and meets client requests for a controllable test cell with variable temperature, airflow, and exposure settings that are applied uniformly.
