• One way air permeability membrane BM9130 - Leadgo Tech

BM9130 is a one-way air permeability membrane, which is covered with microholes. During the vacuum assisted process, small molecules of trapped air and gas can be reliably removed, while the large-molecule resin stays stable in the mould, and control homogeneous fiber volume content. It has been widely used in the vacuum assisted process. It is suitable for use in curing systems, polyester and epoxy systems.

• BYK C8013 coupling agent - BYK Additives

BYK-C 8013 is a coupling agent for carbon fibers. The additive is used in vinyl ester and unsaturated polyester resins that will be subsequently processed with carbon fibers into composite components. Strengths transverse to the fiber are considerably increased and therefore enable a greater design freedom. BYK-C 8013 shows a considerable increase in mechanical strengths particularly in hot curing processes such as SMC/BMC, pultrusion, prepreg or RTM.

The company can provide radar radomes with different frequency bands, wide-band transmission, millimeter wave, high phase consistency requirements, small beam pointing deviation, or extra high wind load requirements. This type of radome can be widely used in 5G communication, weather forecasting and signal detection, etc.

• Pickup box made by SMC composites - CSP Victall Structural Composites

The product 01000 with FAW 10g/sqm, RC50%, areal weight 20g/sqm，is developed in 2016, and put into batch production in 2017. It is now a thin and light in the domestic existing prepreg products. It is applicable to pickup truck model, mass production model and new development model. It not only brings the advantages of weight reduction/reduction to the automobile factory, also can meet the demand of consumption upgrading of pickup users.

• LZ76 3.X CFRP structural wind turbine blade - Lianyungang Zhongfu lianzhong Composites Group

The blade length is 75.8m with maximum chord of 4.7m, pre-bending of 4.5m, bolt circle diameter of 2.8m. Maximum aerodynamic efficiency Cpmax is 0.481, blade mass is 18.3t, and center of gravity from blade root is 22.8m. The product has good aerodynamic performance and can be widely applied to 2.8MW~4.5MW wind turbines in plain, plateau, mountainous area, low wind speed and other onshore wind fields.

• High stiffness and large slenderness ratio carbon fiber roll shaft - Zibo Langda Composite Material

Compared with similar products, the main mechanical properties of the product are increased by 30% and the weight is reduced by 15%, meanwhile the amount of high modulus fiber material consumption is obviously decreased and the manufacturing cost is apparently reduced by optimizing the structural design. The roll shafts are wildly used as the key part of the papermaking machines, ultra-wide & ultra-thin film machines, etc.

• Insulation tank for carrier rocket launching at sea - Shanghai FRP Research Institute

The insulation tank consists of a variety of composite unit parts. It has a length of about 7m, a width of about 3m and a height of about 3m.
