The starting point in a composite product design is specifying the functional requirements and economics. Sometimes a standard formulary is an easy fit – but in most cases customers stretch for more. Lighter, stronger, faster, fewer pieces, fire-retardant, larger, chemical resistant, glossier finish, lower cost – characteristics that will provide a competitive edge.
This is where having the industry leader in advanced materials on your team ups your game. MFG brings a deep bench of material engineers and a dedicated R&D lab to assist you in analyzing your design against the properties of various materials. From there we can recommend a material – either a standard chemistry, a proprietary MFG formula, or a custom solution – that will achieve your targets.
Recognized internationally for having influenced the industry with many material innovations – we invite you to see how MFG’s composites expertise might help advance your composites project.
Our supply base is made up of high quality well-known high performing industry suppliers, and includes strategic partnerships.
A composite is a combination of materials that yield properties greater than the individual ingredients. One material is always a particulate or fiber (reinforcement) and the other a formable solid (matrix).
Plastic resins are the formable matrix within the composite. Virtually all of the physical properties (chemical, electrical, and thermal) are strongly influenced by the resin. Most resins used in composites are the thermosetting type – once formed they cannot be reformed, and they do not melt or flow. Thermoplastics are also used in lower temperature applications. Most often they are enhanced with synergistic organic and inorganic additives to provide additional functionality.
Fibers provide strength, dimensional stability and heat resistance. Additives are easily incorporated into resin systems to provide pigmentation, flame retardence, weather resistance, superior surface finish, low shrinkage and other desirable properties.
Final properties are determined by many factors including the type, amount, and composition of the resin systems and reinforcements. In addition, the use of additives can greatly affect the properties.
Outlined here is information on the various reinforcement and resin systems that are the building block elements for composites. You may find it helpful to download our Design Guide.
Epoxies are best known for their excellent adhesion, chemical and heat resistance, mechanical properties, and outstanding electrical insulating properties. The chemical resistance of epoxies is excellent against basic solutions (best choice for brine tanks).
Epoxies are more expensive than polyesters, and cure times are longer, but their extended range of properties can make them the cost/performance choice for critical applications.
The epoxy resins are formed by a reaction of an epoxide (like epichlorohydrin) with a hardener or polyamine (like triethylenetetramine) that has tremendous cross-linking to create a very tough and yet stiff polymer. The viscosity of epoxies is another step higher than polyesters or vinyl esters. Most epoxies start in the range of 900 centipoise.
MFG’s association with composites for automobiles goes back to the 1950’s. In fact, MFG pioneered mass-production of fiberglass automobile panels with General Motors’ famous 1953 Corvette.
Today MFG is focused on leveraging the intrinsic qualities of composites for advanced structural and under-the-hood components. Our ability to develop advanced material formulas that meet specific objectives gives you access to cutting-edge technology on a flexible outsource basis.
Although many processes, namely SMC compression molding, are used for automotive parts – our proprietary PRIME process has become a standard for structural and quality-critical parts. Using pre-placed reinforcement and production innovations, PRIME produces lighter, more efficient parts.
As a longstanding partner to leaders in the automotive industry, MFG is resourced and staffed to meet the needs of manufacturers in the areas of quality assurance, JIT delivery and project management.
We Optimize Design and Process to Increase Quality and Reduce Investment.
MFG provides valuable design services to help customers optimize composite designs and ultimately, save time and money. As a leading expert in the composite industry, we know first-hand that every composite design has its own unique set of characteristics and features.
Our design team is available to help clients identify unfavorable design features and optimize product design prior to production. Our creative design work can significantly increase quality and savings over the life of a program, and helps customers avoid unexpected, costly changes.
Working with the MFG’s design and research teams in the early development process allows thorough evaluation for Design for Manufacturing & Assembly (DFMA) through the entire process flow: design, materials, tooling, molding, process, finite element analysis, manufacturing and quality.
We work collaboratively to evaluate designs and propose optimized solutions for ease and leaner manufacturing process flow.
With decades of diversified design experience, we have extensive experience with heavy truck, automotive, wind energy, solar, electrification, military, commercial and proprietary products.
We offer critical design support services for new customer development programs to help you with: feasibility & cost savings, conversion studies of metallic part/assemblies to composites, design for six sigma (DFSS) principals and GD&T, and tooling/mold design concepts for cost and process optimization.
