High quality for car size 1.95X4M carbon fiber autoclave in
1. Brief Introduction
In the last ten years we have seen the evolution of new materials,
with excellent mechanical and physical features. The mechanical
resistance, together with the lightness of composite materials, are
finding more and more applications. We call composite material the
product obtained from the polymerization of carbon fibers and
resins, adequately prepared and shaped overlapping coats of fibers
and resin on moulds or cores.
The autoclave is a key equipment for hot-pressing shaping of carbon
fibers and resin matrix composites ( polyimide, bismaleimide, epoxy
resin and thermoplastic resin matrices, etc. ), In fact, the
quality of the product is obtained inside the autoclave reaching an
increase of mechanical features up to 20-30% compared to other
methods of polymerization, which do not foresee the outside
pressurization of the product.
The reliability and the precision of the cycles which can be
obtained with OLYMSPAN autoclave, allow to reach and keep high
quality standards of the product, which is widely used in the
high-tech fields such as aerospace, automotive, electronics,
weapon, traffic, sports equipments and new type of energy, etc.

3. General feature and working process of the autoclave
3-1. General feature
OLYMSPAN Autoclave is a sealed pressure vessel which can be heated
by a forced convection heating unit, where temperature, pressure
and vacuum can be controlled effectively. By means of an advanced
design, consisting of a forced convection fun and motor unit,
output heating power system can be adjusted 0-100%,proportional
control of the pressurization, cooling and exhaust components. It
can obtain an uniform temperature and pressure according to the
process curve. Temperature is check in heating, keeping, and
cooling phase. The heating/cooling gradients can be set by
operator. Pressure is adjusted in pressurization, keeping, release
3-2. Working process
The whole working process of OLYMSPAN Autoclave has 17 segments .In
each segment, the value of temperature, pressure, vacuum and
segment time can be set and monitored by HIM and PC, and the
operation process will be realized by our exclusively developed
software which is based on PLC control system to ensure the full
automatic operation.OLYMSPAN Autoclave is suitable for
manufacturing various composite materials, and it also can
guarantee the perfect product quality.
Recipes for example:
Vacu1:minimum vacuum pressure Vac2: maximum vacuum pressure
Press.1: pre-pressure Press.2:final pressure

6. The TPC control system (Thermal process control)
6-1 Brief introduction of TPC
The autoclaves components and sensors will be monitored and
controlled by the TPC control system. TPC is the Windows XP version
of OLYMSPAN’s computerized control software. TPC was developed by
OLYMSPAN in 2006 to be a single software control platform for most
6-2 Superior Control is Your Key to Performance
Most will agree that in the world of composites manufacturing, the
control system is a key component to assuring autoclave
performance, usability, and reliability. Even the best autoclave
will be crippled by a poor performing control system, especially
when processing large volumes of composites. Because of this fact,
OLYMSPAN has focused a large portion of our R&D efforts on our
control software and the features/capabilities that can improve
processing performance, reliability, and lean manufacturing in
6-3 TPC Software – Features and Capabilities
The autoclave will be controlled by proven TPC computerized control
software, configured in either a single PC or in a primary and
backup architecture (optional).
Ø Ease of use - Even though TPC is by far the most advanced control software
product on the market, the software is still very easy to use. All
screens and features are designed to maximize usability and
increase operator efficiency. For example, part entry, leak-tests,
and other pre-run operations have been stream-lined to reduce the
"door open" times of equipment.
Ø Security- TPC Software include the ability as follow:
l To create user accounts for each operator, supervisor, or
l To assign specific and independent permissions and restrictions
to each user.
l To track user login and logout operations, including time
l To program an auto-logout after a specific period of operator
Ø Excellent reliability – TPC is designed as a client-server package with proven
reliability in the field. It is unacceptable to OLYMSPAN and to our
customers to have control applications that "lock up", and that is
why TPC is designed and tested to meet stringent up-time
specifications. Many of our TPC single-PC systems are controlling
multiple pieces of equipment for years without any major trouble
incident. The production-time of TPC is far better than all
Ø Auto-Redundancy (optional) – TPC supports 100% redundancy of operations and data by means of
a second PC. In a TPC Level II and III systems, two PCs are used
for primary and backup control of the equipment. In the highly
unlikely event of primary PC failure, the backup PC will take
control and continue the run(s) seamlessly. The backup PC will also
have a complete backup copy of the data up until and after the
primary PC failure. During normal operation, both PCs can be
utilized for viewing and/or operation.
Ø Advanced Cure Control - OLYMSPAN is the leader in design and implementation of advanced
controls for the curing of composites in autoclaves of China. The
TPC software contains hundreds of options designed specifically to
enhance the product quality. These include advanced recipe control,
control by air temperature, control by part temperature, controlled
by part gradient, controlled by air gradient, exothermic control,
and other material properties, pro-active control, and many others.
Ø Comprehensive Reporting - TPC has an extensive reporting capability that if far more
powerful and flexible than those provided with other packages. You
can select specific runs by database query and view and/or print
trend date in color plot format, numeric logs, pass/fail reports,
message logs, and a host of other formats. On-screen zooming and
panning on the trend view is also supported.
Ø Remote Control/Viewing - TPC is the only package capable of being viewed and control by
multiple PCs on a single customer network. Unlike other competing
products which utilize PC-Anywhere to "take control" of the
equipment PC, TPC allows concurrent operation and viewing of the
process by operators, engineers, QA/QC personnel, and managers on
the network. As many as 10 concurrent clients are supported.
Ø Up to Date - TPC is maintained and updated regularly to provide the most up
to date features and capabilities as requested by our users.
