News International-French

25 Mar 2011

For the third year in a row, the JEC team had the pleasure of partnering with China Composites Expo to hand out trophies to the twelve CCE – JEC Innovation Awards winners. These awards put the spotlight on innovation in China.

(Published on December 2007 – JEC Magazine #37)

 

 

The third “China Composites – JEC Innovation Awards” were the fruit of a partnership between the 2007 China Composites Expo and the JEC Group. On Wednesday, September 12, 2007, these awards were given out in Beijing as part of the 13th China Composites Expo. Twelve prize-winners were singled out by an independent, eightmember jury. A striking feature of this third presentation was the quality of candidate applications, greater than ever. The competition is now very popular among Chinese companies and foreign groups in China.

 

Innovation: a core element of Chinese dynamism

The aim of the competition is still the same: to promote the quality and innovation of Chinese FRP/composite products. The Awards ceremony took place before the annual gala dinner. Each winner was presented with a diploma and a trophy.

 

We invite you to find out more about the twelve winners of the 2007 CCE – JEC Innovation Awards, below. Next year’s Awards will take place on September 17-19 in Shanghai.

 

The twelve 2007 winners

Four trophies were given out in the Raw Materials category, and eight in the Application category.

 

Continuous glass filament mat
Danyang Zhongya Glass Fiber Company Ltd.

 

Application:

Used as reinforcement in pultruded and complex-shaped moulded products.

 

Technical characteristics:

  • One of the best-performing products in China compared with similar products. The glass fibre is made of non-alkali glass.
  • New type of single filament, multidirectional, overlaid nonwoven fabric. The composite products reinforced with this highquality mat have improved integral strength, good surface finish, elegant appearance and limited cracks. The mat is especially suitable for pultrusion products.
  • One-step process with automatic drawing and traversing; special sizing and binding; and integrated drafting, drying and crosslinking reaction.
  • No gathering, spooling, chopping or ejecting; the filaments are laid randomly in a curved pattern to form the mat. As a result, the mat has very good isotropic properties, a good resi wet-out rate, and improved tensile breaking strength (especially wet strength), ideally meeting the process requirements.

 

GF/PPF compounding yarn
Taishan Fiber Glass Inc.
Co-developer: East China University of Science and
Technology

 

Application:

The yarn was used to make a safety helmet for fire-fighters, construction workers, motorcyclists and others.

 

Technical characteristics:

  • Low weight
  • Excellent impact and pierce resistance
  • Water and chemical resistance
  • Potential recyclability

 

Turane resin
DSM Composite Resins AG

 

Application:

Turane resins were developed for advanced composite applications such as aerospace, automotive and windmill blades, which all require high strength coupled with low weight. The cure chemistry of Turane resins gives a cure profile from slow to very fast, making them ideal for fully controllable vacuum resin infusion. The Nuna4 solar-powered vehicle weighs in at barely 190 kilograms. Cuttingedge aerospace and Formula1 technology were used to produce a car that is stronger, lighter and safer than its predecessors.

 

Technical characteristics:

 

Turane, a new family of thermoset materials, stands for “thermosetting urethanes”. Cured Turane resins are distinguished by high flexibility and toughness, with the structural performance of epoxy resins but faster processing characteristics. Due to their superior adhesion to fibre reinforcements, the composites exhibit advanced behaviour and quality.

 

3D fabric manufacturing technology
Textile College of
Donghua,
University of Shanghai

 

Application:

The fabric is used as reinforcement in sandwich composites, in energy- and impact-absorbing materials, and in sound- and heatinsulating materials.

 

Technical characteristics:

 

This is a kind of 3D textile fabric formed with two biaxial weft-knitted structures and a layer of spacer yarns. It is characterized by a high planar structural stability and easy variation of thickness in comparison with current spacer structures. The maximum thickness can reach 2.5 cm. The structure also has higher resistance to delami-nation and better structural integrity under impact loads.

 

ECV radiology tabletop
Beijing TBHY Composites Institute
Co-developer: Dongruan Philips Medical Equipment System Corp. Ltd.

 

Application:

No inclusion is to be allowed in the working area of the tabletop, except for the 620 mm long joining part (non-working area).

 

Technical characteristics:

 

  • The inspected deformation is 10.5 mm, less than the 12.5mm norm, which proves the table’s rigidity satisfies operational requirements.
  • The material used is UDC instead of prepreg CW used by Philips for the original product. Compared to CW, UDC has more longitudinal layers for the same skin thickness.

The volume fraction of 0º layers is 70%. So the UDC tabletop has higher strength/Young’s modulus.

  • UDC’s Al equivalent is lower, which makes the picture clearer.
  • The price of UDC is about one-third that of CW. Because UDC is stronger and more rigid than CW, 71IG PMI (used by Philips) could be replaced with 51IG PMI. This way, the cost of materials is significantly reduced.

 

Composite post insulator for 1000 kV UHV trans-mission lines
Wuhan University of Technology, School of Materials Science and Engineering
Co-developer: National Net Wuhan High Voltage Institute

 

Application:

Used in 1000 kV UHV transmission lines as post insulator.

 

Technical characteristics:

 

Composite post insulators are applied extensively in HV (high voltage) transmission lines due to their low weight, good insulation properties, convenient production, etc. In China, 1000 kV UHV transmission lines are a key item accounting for huge investments in the 11th five-year plan. The corresponding composite post insulators are now in the design and testing phase. They are almost twice as high as those currently used, imposing higher insulation, strength and rigidity requirements for the composite materials. The insulator is 12 m high and 600 mm in diameter. Insulation voltage: 1000 kV, bending moment: 16 x 12 kN•m, torque: 8 kN•m. Its axial rigidity and weight were improved through optimized pultrusion, tape-laying and winding techniques. The epoxy-based composite material offers excellent electrical properties: electric strength: 37.0 kV/mm, volume resistivity: 1.34x1017, relative dielectric constant: 2.74.

 

High-power radar dome
Shanghai FRP Research Institute

 

Application:

The product protects the radar antenna against air damage, lowers the design power of antenna driving devices, reduces the actual energy consumption required for antenna rotation, reduces the amount of daily maintenance, extends the service life of the radar, and reduces the risk of radar shutdown due to environment and weather changes.

 

Technical characteristics:

 

This innovative product uses a new type of composite material with the following characteristics:

  • High strength: can resist strong typhoons at sea and ensures all-weather operation of electronic equipment.
  • Good weather resistance: can effectively resist the corrosion of salt fog, UV light, mould fungus, rain, snow, etc., thereby improving the service life of electronic equipment.
  • Excellent insulation: provides a good thermal insulation layer, especially in extreme weather conditions, and ensures an ideal working environment for advanced electronic instruments and devices.
  • Can easily penetrate electromagnetic waves; can sustain reflected power of electromagnetic waves much stronger than that of a microwave oven.
