Benefits of Composite Manufacturing

Take a look at why composite manufacturing could be the right solution for your project.


Composites are stronger than other materials such as steel. The two primary components of composites, fibres and resins, contribute to their strength. Fibers carry the load, while resins distribute the weight throughout the composite part.


Composites are light in weight compared to most woods and metals. Lower weight contributes to things like fuel efficiency in cars and airplanes and lighter objects are easier to transport and install.


Composites resist damage from weather and harsh chemicals which makes them a good choice for applications that face constant exposure to salt water, toxic chemicals, temperature fluctuations and severe conditions.


A wide range of material combinations can be used in composites, which allow for design flexibility. The materials can be custom tailored to fit unique specifications of each application. Composites also can be easily molded into complicated shapes.


Simply put, composites last! Structures made with composites have long life and require little maintenance. Many products made with composites, such as boats, have been in service for more than half a century.
