Products in Military & Defense: Prepreg

APCM DA 4518 E-Glass is a modified epoxy system coated on heavy weight unidirectional E-Glass fibers. This product is designed to build excellent unidirectional strength using a minimum number of plies. DA 4518/E-Glass Uni also features extended room temperature out time and service temperatures to 300°F.

Park’s E-722 is a modified 350°F cure epoxy system with excellent processing characteristics for vacuum bag, press, and autoclave molding.

APCM DA 409U/G35-150 is a tough, versatile, modified epoxy resin prepreg that cures at 250°F, a standard modulus 150 g/m2 carbon prepreg tape which can also be supplied as a 200g/m2 or a 300 g/m2 prepreg.

PRF Composite Materials RP442 is designed to give an initial cure at low temperatures with enhanced toughness and higher service temperature, giving great flexibility in component manufacture. The system also has a longer out life for a low temperature system: up to 30 days at 20°C. RP442 can be supplied on a variety of PRF’s high quality reinforcement fabrics.

Epoxy resins are a family of thermosets that offer a broad variety of performance characteristics. Epoxies are well known for their strength, toughness and their ability to be formulated to cure under a wide variety of time and temperature conditions. Epoxy prepregs are structural materials that are used in a wide variety of applications in the composites industry. In protective applications they can provide structural support to strengthen and stiffen soft armor structures as well as to reinforce ceramic plates to provide multi-hit resistance to armor piercing rounds.

PRF Composite Materials RP542-1 is a controlled flow, tough epoxy prepreg system formulated for the manufacture of high performance structural composite parts requiring very good impact strength properties. The system has been formulated for a medium temperature cure of 80 - 120°C under vacuum or autoclave pressure and is also suitable for press molding. Fully cured, this system has a dry service temperature capability up to 120°C. The component surface finish with this system is excellent. The tack level of this system can be adjusted to meet the constructor’s individual requirements and will be retained for up to 40 days at 22°C making this system suitable for the manufacture of large composite components. RP-542-1 can be supplied on most of the vast range of PRF reinforcement materials in widths up to 1350 mm wide.

185HR laminate and prepreg materials are manufactured using Isola’s patented technology, reinforced with electrical grade (E-glass) glass fabric. This system delivers a 340°C decomposition temperature, a lower Z-axis expansion and offers lower loss compared to competitive products in this space. The 185HR system is also laser fluorescing and UV blocking for maximum compatibility with Automated Optical Inspection (AOI) systems, optical positioning systems and phot imageable solder mask imaging.

PRF Composite Materials RP542-4 is a controlled flow, toughened epoxy prepreg system formulated for the manufacture of high performance structural composite parts requiring very good impact strength properties. The system has been formulated for a medium temperature cure of 80 - 120°C under vacuum or autoclave pressure and is also suitable for press molding. Fully cured, this system has a dry service temperature capability up to 120°C. The component surface finish with this system is excellent. The tack level of this system has been optimized to meet the constructor’s requirements and will be retained for up to 60 days at 20°C making this system suitable for the manufacture of large composite components. RP-542-4 can be supplied on most of the vast range of PRF reinforcement materials in widths up to 1350 mm wide.

370HR laminates and prepregs, deigned by Polyclad, are made using a patented high performance 180°C Tg FR-4 multifunctional epoxy resin system that is designed for multilayer Printed Wiring Board (PWB) applications where maximum thermal performance and reliability are required. We manufacture 370HR laminates and prepregs with high quality E-glass glass fabric for superior Conductive Anodic Filament (CAF) resistance. 370HR provides superior thermal performance with low Coefficient of Thermal Expansion (CTE) and the mechanical, chemical and moisture resistance properties that equal or exceed the performance of traditional FR-4 materials. 370HR is used in thousands of PWB designs and has proven to be best in class for thermal reliability, CAF performance, ease of processing and proven performance on sequential lamination designs.
