Mc² Commercial Vessels

Mc² Commercial Vessels, a division of the McConaghy Group, was established in 2014 to provide advanced composite manufacturing solutions to the Commercial Vessel and Naval sectors.


The resources and contacts of Tiger Group have proven a significant advantage in expanding to this business domain thanks to their strengths as a commercial ship owner and manager.

Mc2 Commercial Vessels


Recognising the as yet unrealised benefits that composites can bring to commercial vessel sectors, Mc² Commercial Vessels is introducing a new generation of high-speed and high-efficiency craft and components that will set a new benchmark in operating efficiency, speed of service and operating characteristics. In addition, Mc² Commercial Vessels has initiated research into and prototyping of components for commercial vessels such as doors, superstructure components, hatches, etc.


50 years of delivering performance:

          • Originated in Australia at the forefront of composite applications;

          • Combined with a competitive cost structure and highly-skilled manufacturing base in China;

          • Backed by the technical expertise of McConaghy’s New Zealand design office;

          • Strengthened by the financial and strategic contributions of Tiger Group Investments.

Why Composites

Why Composites


Innovation in production methodologies and advancement of composite knowledge have been in the DNA of McConaghy Group since the beginning.

We are constantly innovating, testing and improving our techniques, applying composite technology to new fields as well as refining the production, mechanical properties, and minimising weight of composites in existing applications. We have assembled a team of in-house experts covering all facets of composite building to create a company with unique capabilities.



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.
