PPE launches resin flow technology at JEC
Reinforced Plastics Volume 59, Number 3 May/June 2015
‘If we can control warp and weft tension we might be able to influence resin flow,’ said Dr Turner. ‘We also want to push the machine to the limit of its capabilities. For example, it isn’t designed to produce three dimensional structures, but we are hoping to create structures like pockets and flaps.’
Honeycomb structure If the researchers are successful, they could be able to weave materials that could be opened up to form a series of boxes or a honeycomb structure that would give the completed composite component additional strength. AMRC; www.amrc.co.uk
PPE launches resin flow technology at JEC PPE has launched its EASYPERM system, which measures and evaluates the ability of reinforcement to let resin flow, at the JEC Composites Show. The technology can characterize flow in three dimensions and is also a quality control system. The company says that EASYPERM is the only system on the market that offers an industrial solution for measuring the permeability of a dry reinforcement through thickness and in-plane. It makes it possible to evaluate the capacity of reinforcement to be impregnated by a liquid resin. EASYPERM relies on pressure measurement via a network of sensors, which is then postprocessed using Darcy’s law.

‘This is a crucial step in performing filling simulations for large and complex parts, but also for process optimization in the case of ˆ me Raynal, high production rate,’ said Je´ro PPE’s sales and export director. ‘Particularly as it can be used to characterize all types of fiber (glass, carbon, aramid, flax, hemp, etc.), while minimizing the amount of material needed.’ ‘EASYPERM uses a measurement technology which has been developed and used over the past ten years, but also integrates the latest developments in measurement precision,’ said Henri Perrin, PPE’s R&D manager.

Dassault Syste`mes launches new SOLIDWORKS app Dassault Syste`mes has introduced SOLIDWORKS Industrial Design, the second SOLIDWORKS application on its 3DEXPERIENCE platform. The application is designed to improve the product design process by supplying users with a cloud-based tool, allowing them to design and collaborate on complex organic shapes from concept to final product more freely.
‘The needs of the CAD user community have been a beacon of technological innovation and we are committed to developing tools that respond to evolutions in the product design process, from a technical perspective as well as a collaborative one,’ said Gian Paolo Bassi, CEO, SOLIDWORKS, Dassault Syste`mes.
Design evolution Designers can create complex shapes in 3D and add mechanical data directly to a model without changing the product design software or environment. Concept sketching, integrated freeform and parametric surface/solid modeling, direct editing, realistic rendering and simplified design evolution tools are all available.

Introducing Engineering Advances In 2015, Elsevier’s engineering journals will be making high impact reviews of on the latest available to all: Engineering Advances. Via MaterialsToday.com, Engineering Advances will serve as a platform for collecting together specially commissioned reviews from experts in their respective fields. Sustainable development will form the theme of the first selection of papers, but in time the
collection will cover a broader range of topics including renewable energy, thermal engineering, structural and geotechnical engineering, robotics, manufacturing, chemical engineering, water engineering, fuel cells and construction materials. Complementing the freely accessible new, reviews and articles already available from Materials Today, these Open Access Engineering Advances papers will help
transfer knowledge between academic and industrial communities. In 2015, the papers will provide a base for both practitioners and researchers to explore how materials science and engineering can offer solutions to the challenge of sustainable development.

resin flow through the fabric isn’t symmetrical, despite the weave pattern being perfectly symmetrical. They believe this may be a result of slightly differing yarn tensions within the fabric. Now they plan to increase their knowledge by experimenting with different tensions for the warp and the weft.
