Frequently asked questions about composites

Find answers to common questions about curing agents, hardeners, and accelerators, including their role in resin systems, processing, and performance.

Ask a question

Composite manufacturing typically uses a combination of resins, reinforcements, fillers, additives, and curing agents to achieve specific mechanical and performance properties. These materials are selected to deliver strength, lightweight performance, durability, and consistency across different composite systems.

Thermoset composites use resins that cure irreversibly to form rigid, cross-linked structures, while thermoplastic composites use resins that can be reheated and reshaped. Material selection depends on processing method, performance requirements, and end-use application.

Raw materials directly influence composite strength, toughness, and impact resistance through resin selection, curing systems, and the use of performance additives. The combination of epoxy resins, appropriate curing agents, and tailored accelerators allows manufacturers to optimise mechanical performance for structural composite applications.

Cure speed in composite systems is controlled through the selection of curing agents, hardeners, and accelerators, allowing manufacturers to tailor processing time and temperature. Products such as anhydride curing agents from Lindau Chemicals and accelerators from A&C Catalysts, including Technicure® and Resicure™ ranges, are commonly used to achieve controlled and repeatable cure profiles.

Lightweighting and density control are achieved through the use of specialist resins, fillers, and formulation techniques that reduce mass while maintaining mechanical performance. Functional minerals such as Magsil talc are often used to modify density, stiffness, and processing behaviour in composite formulations.

Resistance to water, chemicals, and heat is achieved through the selection of suitable resins, curing systems, and performance additives. These materials help composites perform reliably in demanding environmental and industrial conditions.

Surface finish and scratch resistance are enhanced through the use of functional fillers, additives, and resin modifiers that improve surface hardness and durability. These materials help achieve consistent appearance and long-term performance.

Yes, custom blends and tailored formulations can be supported through RBH Repack. Our repacking and contract blending services allow bespoke material combinations, trials, and scale-up support using controlled and compliant processes aligned to composite formulation requirements.

Specialist distributors provide market-specific expertise, access to proven materials, and reliable supply chains. This allows composite manufacturers to source suitable raw materials efficiently while maintaining consistent quality and production continuity.
