Composites

Continuous Fibre-Reinforced Thermoplastic Plates
For applications where the mechanical requirements are too high for unreinforced or short fibre-reinforced plastic stock shapes, continuous fibre-reinforced thermoplastic plates offer an excellent alternative. Thanks to the continuous fibre reinforcement, usually a woven fabric of glass or carbon fibers, they have mechanical properties otherwise achieved only by metallic materials. At the same time, they are significantly lighter than most metal-based alternatives.

Through the use of thermoplastic matrix materials, the plates nevertheless have the same advantages as unreinforced plates made from thermoplastic materials: high impact strength, constant properties over a broad temperature range, chemical resistance and high elongation at break. For some applications, the intrinsic vibration damping of the matrix can also be an advantage.

Plates made from continuous fibre-reinforced thermoplastics can be processed into finished parts of outstanding quality with minimal tolerances. Alongside water jet cutting, conventional processing methods are also suitable – assuming suitable facilities and processing parameters.

Ensinger has widened its portfolio of composite plates to include three new materials: TECATEC PPS CW50, TECATEC PEI GW50 and TECATEC PC CW50. TECATEC PPS CW50 black (PPS CFK – Polyphenylene sulfide, carbon fibre-reinforced) offers excellent high-temperature resistance, has very good chemical resistance and dimensional stability over a broad temperature and humidity range and its carbon fibre reinforcement increases stiffness and strength. Their TECATEC PEI GW50 natural (PEI GFK – Polyetherimide, glass fibre-reinforced) offers high continuous service temperature (170°C), good electrical insulation, is fire, smoke and toxicity retardant (FST) and its glass fibre reinforcement increases the mechanical properties while keeping costs down. And TECATEC PC CW50 black (PC CFK - Polycarbonate, carbon fibre-reinforced) offers outstanding appearance thanks to crystal-clear, transparent matrix, high impact toughness and its carbon fibre reinforcement increases stiffness and strength.

Ensinger produces the thermoplastic composite plates to customer-specific requirements, with maximum dimensions of 525 x 625 mm. The manufacturer is also flexible when it comes to the plate thickness: in the range 0.5 to 95 mm, any thickness is possible.

Thermoset Composites
Since 1980, Accurate Plastics, Inc. has provided NEMA LI-1 and MIL-I-24768 certified Acculam ® thermoset composites in sheet, tube, rod, and other forms.

Thermoset plastics are historically significant and still innovating today. They are unique composites of cross-linking resins with reinforcing materials that are permanently cured by heat and pressure. Once cured, they become very rigid, durable and maintain physical properties in hot conditions better than thermoplastics. This plastic was pioneered in the early 20th century and found many uses in the electronics industry in the mid-20th century and spawned additional grades during the industrial revolution. Typically referred to as Grades G10, G11, G9, G5, G7, G3, FR4, FR5, CE, LE and XX. Today they continue to expand in electronics, aerospace, gaskets, heavy equipment, medical equipment, magnetics, energy and other applications. Recently released Acculam Carbon Fiber Laminates are a proprietary value-engineered product line providing all the high-performance of traditional Carbon Fiber at significantly competitive prices. They are available in sheets and tubes.

These composites may be combined with other components such as metals, etc., to develop unique properties that allow flexibility in the design of devices. Where high mechanical strength and resistance to heat or electricity are necessary, thermoset composites allow designers a flexible, durable, lightweight option for replacing thermoplastics, metals and other high weight components.
