JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
JEC 2011 will see Guang Wei Composites, the leading prepreg supplier in China, announce two developments to the market - the recent awarding of the Chinese patent for their Wind Energy semi-preg materials and the opening of a new 30 Million RMB Research and Development Facility.
Guang Wei Semi-Pregs
The Guang Wei semi-preg materials are constructed from layers of dry reinforcement fibres and a catalysed resin matrix film. Unlike conventional prepregs, the fibrous reinforcements in Guang Wei semi-preg materials are supplied to the end-user in a non-impregnated form meaning that it is only during the final curing process that the fibres and resin matrix film are combined and the laminate ply wets out.
The dry reinforcement layers allow the laminate stack to release air between the plies without debulking, which ensures that cured laminates reliably exhibit a very low void content with simple vacuum bag processing, offering the customer significant benefits in quality control.
Guang Wei’s semi-preg materials are ideally suited to the serial manufacture of large composite components, in particular, the critical sections of wind turbine blades where exceptional laminate quality and mechanical performance is required.
Guang Wei Research and Development Facility
Guang Wei has invested 30 Million RMB (3.3million Euros) in a new state of the art Research and Development facility. The 1000m2 facility will house 40 trained technicians who will focus specifically on Composite material product developments such as surface coatings, fire retardant products for Aerospace, adhesives and lightweight carbon fibre products for Marine and Sports and heavyweight materials for Wind and Infrastructure.
The facility that will be located at the Guang Wei Composites headquarters in Weihai, Shandong will open in late January.
Every year, JEC Composites Show is the place where innovations are launched. 2011 is no exception. Here are in this feature few of these innovations. Many others will be announced during the Show...
