JEC COMPOSITES MAGAZINE - Issue #79 - March 2013 - 74

At JEC Europe 2013, SCIGRIP, the global
leader in adhesive solutions, is launching
an enhanced product for bonding dicyclopentadiene (DCPD) composites. As a result of
their developmental work with SG600, a methyl methacrylate (MMA) structural adhesive,
SCIGRIP has produced an advanced product
that is suitable for bonding many difficult
substrates including grades of DCPD.

Multi-sector

Many grades of DCPD adhered successfully with SG600 without time-consuming preparation techniques such as flame treatment. SG600 is a cold curing solution that produces tough and
fatigue-resistant bonds, and also features ratio adjustable cure
times and rheology compatible with robotic application. SG600
has also performed well in trials bonding ABS, PVC and SMC
as well as traditional PE, VE or epoxy composites. SCIGRIP will
additionally be featuring their 10:1 MMA range, now in full EU
and USA production. These include SG230HV, the high-gap-fill,
low-exotherm MMA for large composite component assembly,
and SG300, popular in many transport sectors for tough bonding of composites and metals without primer. www.scigrip.com

New independent FP
programming software from Ingersoll

Over the past year, Ingersoll M.T. introduced several new
developments for its AFP line of equipment, including a
new stand-alone software package for the programming of
automated fibre placement machines. Ingersoll partnered with
Lockheed Martin for the development of CPS2, a successor to
its current integrated composite programming software, iCPS.
This development intends to provide more flexibility and easeof-use throughout automated composite processing.
CPS2 is independent of both the AFP machine and the software’s operating system and interfaces with any of the more
commonly used CAD programs. Common, independent
software offers more freedom from supplier-specific products
and will provide the user with significant cost-savings over the
life-time of multiple machines.
CPS2 is based on more than 20 years of experience in composite automation software, but also offers new functionality in
addition to improvements on existing features. More advanced
path planning and collision avoidance are a part of the new software package. Machine program improvements, such as smooth
motions based on NURBS and improved off-part motion/path
optimization will be complemented by a total solution software
bundle to support AFP throughout the entire process. Offering
a single package with similar “look-and-feel” to assist with initial
part design, simulation, machine motion optimization and final
layup will reduce training and streamline the design and production process.

New internal mould relaese
additives for DICY-cured epoxy resin

Axel Plastics Research Laboratories announces two new
internal mould release additives for DICY (dicyanamide)
-cured epoxy resin: MoldWiz®INT-1322 and INT-1329. By nature,
DICY-cured epoxies are among the most tenacious in their bonding properties, prompting many in the industry to search for more
effective ways to release DICY epoxy, resins, compounds, prepregs
and laminates. In the past, many internal mould release formulations proved ineffective, often killing the cure of the DICY resin
and leaving the polymer under-cured and tacky. AXEL’s new proprietary formulation MoldWiz® INT-1322 has been proven to have
no impact on the cure kinetics of imidazole- or amine-accelerated
DICY. For non-accelerated DICY-cured epoxy resin, AXEL offers
INT-1329, which is formulated for the higher process temperatures
associated with these DICY systems. Initial evaluations of these
two new internal mould release additives indicate that they have a
good pot life in resin mixes and provide good release from moulds
and substrates, making them equally suitable for use in epoxy resin,
epoxy compounds and prepregs. MoldWiz INT-1322 and INT1329 are proprietary synergistic blends, comprised of organic fatty
amine and acid derivatives with surface active agents. The products
are 100% active and generally effective at addition levels of 0.5-4 %
based on resin system weight and dependent on process, fillers, etc.

Laser micromachining
of composites

> Booth T20

For several decades, composite materials have gradually
replaced metals in many industrial applications. Thanks to
improved processes to shape and machine composites, production
costs and time have significantly decreased, allowing use in many
fields such as automotive, aeronautics, and other fields requiring
light-weight constructions.
However, processing of composites remains a challenge: the
specific stack structures of carbon fibres impregnated in a highly
abrasive and heat-sensitive plastic matrix is a constraint for many
machining schemes. In addition, traditional machining technologies involve contact forces that can induce delamination between
the finer layers.
Alphanov has developed innovative laser processes for machining composite materials with ultimate precision and quality. Laser
processing is inherently non-contact, which drastically reduces
the risk of delamination. The main challenge lies in managing
the energy deposition to limit thermal degradation caused by the
heat transferred along the carbon fibres. Based on its extensive
laser fleet, Alphanov has developed a deep understanding of the
light-matter interaction phenomena and recently studied the influence of energy density on the extent of the heat affected zone, the
ablation rate and the quality of machining. This helps choosing the
right process parameters for the right material in order to fulfil the
requirements with high-quality and fast processing times.
