50 years of
EXPERIENCE IN COMPOSITE
to take on any challenge, no matter how big or complicated
McConaghy’s Commercial Composites division was established in 2014, originally to provide composite solutions to both the Naval and commercial sectors.
Drawing on the resources and contacts of the Tiger Group as a commercial ship owner and manager, has enabled McConaghy to significantly expand its offering to this sector in recent years.
McConaghy's Commercial Composite division continues to build marine vessels for the commercial sector, supplying a new generation of high speed, high efficiency, craft and components that set a new a benchmark in operational productivity, speed of service and operating characteristics. Our 50 years of composite build expertise means that McConaghy can also provide everything from travel cases for musical instruments to shoreside architectural constructions, on a massive scale.
In addition to this, McConaghy Commercial Composites has initiated research into, and the prototyping of, advanced components for commercial vessels such as doors, superstructure frameworks and hatches, and components for renewable energy generation, the construction industry and aerospace sector.

The benefits of composites:
High Strength - Composite materials can be designed to meet the specific strength requirements of an application. A distinct advantage of composites, over other materials, is the ability to use many combinations of resins & reinforcements, & therefore custom tailor the mechanical & physical properties of a structure.
Lightweight - Composites offer materials that can be designed for both lightweight & high strength. In fact, composites are used to produce the highest strength-to-weight ratio structures known to man.
Corrosion Resistance - Composites provide long-term resistance to severe chemical & temperature environments. Composites are the material of choice for out-door exposure, chemical handling applications & severe environment service.
Design Flexibility - Composites have an advantage over other materials because they can be moulded into complex shapes at relatively low cost. The flexibility offers designers a broad range of design freedom, which is the hallmark of composite achievement.
Durability - Composite structures have an exceedingly long life span and exceptional fatigue properties. Coupled with low maintenance requirements, the longevity of composites is a benefit in critical applications. In a half-century of composite development, well-designed composite structures have yet to wear-out.
What is a composite?
A composite is defined as a structure containing two or more components, (in the case of fibre reinforced composites this is the fibre & a resin). A composite containing two types of fibre, eg. carbon & glass, is known as a hybrid composite.
Composites are broadly known as reinforced plastics. Specifically, composites are a reinforcing fibre in a polymer matrix. Most commonly, the reinforcing fibre is fibreglass, although high strength fibres such as aramid & carbon are used in advanced applications. The polymer matrix is a thermoset resin, with polyester, vinyl ester, & epoxy resins most often the choice of matrix. Specialised resins, such as, phenolic; polyurethane & silicone are used for specific applications.
Common household plastics, such as polyethylene, acrylic, and polystyrene are known as thermoplastics. These materials may be heated and formed; then can be re-heated and returned to the liquid state. Composites typically use thermoset resins which, begin as liquid polymers & are converted to solids during the moulding process. This process, known as crosslinking, is irreversible. Because of this, composite materials have increased heat & chemical resistance, higher physical properties, & greater structural durability than thermoplastics.
Carbon fibres are usually mixed with resin to form a "Pre-Preg" (Pre-impregnated) sheet, wound between release paper. This carbon/resin pre-preg can be formed into a huge variety of end products.
Origins of composites
The origins of textile reinforced composites are linked to the development of glass fibres, which commenced in 1938 by the Owens Corning Fibreglass Corporation (USA).
As the technology of textile-reinforced composites expanded, a growing demand from the aerospace industry for composite materials with superior properties emerged. In particular, materials with (1) higher specific strength, (2) higher specific moduli, & (3) low density were required. Carbon fibres have also been developed to meet the demands for other desirable properties such as good fatigue resistance, and dimensional stability.
About 65% of all composites produced use glass fibre & polyester or vinyl ester resin, and are manufactured using the open-moulding method. The remaining 35% are produced with high volume manufacturing methods or use advanced materials, such as carbon or aramid fibre.
As the technology of producing composites has advanced, other resin systems, fibres and cores have been developed to supply the market.
