JEC 2011 saw Guang Wei Composites 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.
According to Guang Wei, 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 designed for the serial manufacture of large composite components, in particular the critical sections of wind turbine blades where high laminate quality and mechanical performance is required.
Guang Wei Research and Development Facility
Guang Wei has also invested 30 Million RMB (3.3million Euros) in a new state of the art Research and Development facility. The 1000m2 facility houses 40 trained technicians who will focus specifically on composite material product developments such as surface coatings, fire retardant products for aerospace, lightweight carbon fibre products for marine and heavyweight materials for wind & infrastructure.
The facility, recently opened in February, is located at the Guang Wei Composites’ headquarters in Weihai, Shandong.
