traceability
The product
Composites are engineered materials made by combining two or more elements. For example, fibre-reinforced polymers are made from fibres (carbon, glass, Kevlar, etc.) and a polymer/plastic, such as epoxy. Resins or epoxies are required to bond the fibres together at a microscopic level, in order to achieve unique properties. When combined, these elements produce a very strong, but extremely light material. The use of resins requires that rolls of prepreg fabric must be stored at low temperatures (0°C) because the resin transforms at warmer temperatures. The fibres are used in textiles, woven goods (i.e. plain weave fabrics) or in unidirectional products, such as tape. The strength and light weight properties of prepregs are key reasons why aircraft, automobile, sporting goods and wind turbine manufacturers are increasingly using them in their products. These industries call for strict adherence to engineering requirements, which entails stringent tracking, recording and processing of prepreg materials to ensure parts are defect-free. To meet the demand, remain competitive, save time and costs, prepreg manufacturers must streamline roll storage, processing and shipping processes within the required temperature ranges. is exposed to room temperature, causing the resin to progress into a chemical transformation which reduces shelf life. If the roll is continually exposed to room temperature, the manufacturer must eventually scrap the remaining product or spend considerable time retesting it to establish if there is additional shelf life. Careful tracking of cumulative time out of 0°C storage becomes a critical issue that must be monitored and recorded carefully. Composite processors and OEM facilities currently follow similar storage, monitoring and recording procedures for cumulative out-time for every roll of prepreg material. Without an automated temperature monitoring system in place, the process involves manual tracking. As a prepreg material comes off the production line, it is assigned a tracking number. As it enters storage, time is noted on a paper chart and subsequently recorded each time the roll is moved in and out of storage, adhering to customers’ out-time traceability requirements. Large prepreg manufacturers or users may have as many as 500 rolls in storage at one time, so this process can be extremely labour and time intensive. Other issues related to a manual process include human error, lost paperwork and lack of traceability. Prepreg manufacturers and users can benefit from an automated, traceable, error-free way to monitor, track and record cumulative out-time. monitors prepreg rolls from fabrication to shipment, and can further track them in transit to the customer. RF data loggers send signals to a wireless receiver, which is a gateway between the wireless network and corporate IT systems. Wireless repeaters and Bluetooth range extenders boost signals from loggers to receiver, in order to overcome physical obstacles in line of site. FlashRF Manager is a unique, interactive, multi-level facilities mapping software that gathers, logs, tracks and reports data. As a prepreg roll comes off the fabrication line, a barcode label is printed, attached to the roll and correlated to a DeltaTRAK FlashLink RF logger which is also placed on the roll. Each roll would have a wireless logger attached to it before being placed into the freezer and, at this point, the system begins clocking shelf life. As each roll leaves the freezer, the logger sends the time information to the network and, upon returning to the freezer, time back in is transmitted. The software then calculates out-time, a percent of life remaining for each roll, based on time spent out of cold storage. Data is reported in graph, text or spreadsheet (Excel) format. The software can also be programmed to emit an audible alarm on the computer and/or send an email alert or text message when the product is close to out-time limits. The system also allows personnel to access data remotely. Any manufacturer with TATS materials susceptible to shortened shelf life would benefit from a wireless, automated time and temperature system with round-theclock monitoring capability. Being able to track product shelf life is not only valuable, but required in many industries that must adhere to specific design requirements. Manual monitoring on paper charts is time consuming, costly, prone to human error and lacks real-time traceability. These challenges are easily addressed with an automated, wireless monitoring system. n

jec composites magazine / No66 July - August 2011
OEMs, such as Boeing and Airbus, pass on their process standards to prepreg suppliers in order to ensure materials are delivered according to quality specifications for their industry. An OEM also requires the prepreg supplier to show traceability of product within set parameters. The auditable documentation must detail the total out-time of the material, from fabrication until it is received by the OEM.

Automating out-time
DeltaTRAK® offers an automated, wireless, real-time monitoring, recording and alarm system which gives managers the product visibility and traceability they need to meet internal and external quality control and regulatory guidelines. The FlashLink RF Wireless System™ collects information around the clock, with real-time data visible on a PC monitor at any time, while also storing it electronically. Alarms can be set up to send alerts to personnel, indicating occurrences of temperature excursions or amount of out-time (shelf life) remaining for inventory management purposes.

Manual tracking

At the manufacturer’s facility, prepreg rolls are typically kept at 0°C in temperaturecontrolled storage rooms. When the manufacturer receives an order, it may be for all or only a portion of the roll. He must remove the product from storage, cut the roll as needed and return the remaining product to storage. While the roll is out, it
