Continuous fiber reinforced thermoplastic composite is a new product developed by Shanghai Leadgo-tech Co., Ltd. in 2018. The project adopts advanced resin melt impregnation process and yarn spreading technology to prepare prepreg with uniform thickness, smooth appearance and high performance. Continuous fiber reinforced thermoplastic composites with high strength, high toughness and high stiffness are widely used in aerospace, train, automobile, container, construction, pipeline, sports and leisure fields. The main product forms include: unidirectional prepreg tape, composite laminate, sandwich board, etc.

1. Unidirectional prepreg tape:

  The unidirectional prepreg tapes are made of polypropylene (PP), polyethylene (PE), nylon (PA), polyphenylene sulfide (PPS) and other thermoplastic resins as matrixes, continuous glass fiber and carbon fiber as reinforcement materials, which are manufactured by melt impregnation process. They can be used as composite pipe reinforcement, winding gas cylinder, etc.

Product features:

Ø  The resin matrix and reinforced fiber can be selected according to the needs;

Ø  Natural color and black are conventional product colors, other colors can be customized;

Ø  The material has light weight, high specific strength, high specific modulus and excellent mechanical properties;

Ø  Dry storage, long storage life;

Ø  Recycling, environmental protection, sustainable development;

Ø  Materials and products have no harmful volatilization;

Ø  Good corrosion resistance and moisture resistance;

Ø  The product design is flexible and the product performance is controllable;

Ø  Advanced technology, automatic production.Ø   

The above data are the average values determined by the laboratory, and are only used for reference, not as product standards.

2. Composite laminate:

Composite laminate is made of unidirectional tapes with orthogonal ply. The unidirectional tapes can be laid in different order with different angles (0°、±45°、90°). Under the heating and pressure of the compound machine, the fibers continuities are maintained, and at the same time, the laminate is reinforced in each direction according to the design, which has better mechanical properties and lighter weight. It can be used to replace steel laminate, glass fiber reinforced plastic and other materials, as well as in various boxes and tanks.

In addition, the thickness, gram weight and strength of the composite laminate can be customized according to customer requirements, and it can be bonded with anti ultraviolet and anti-aging films, as well as non-woven fabrics and decorative films.
