Reinforcement Materials
Composites are made up of individual materials referred to as
constituent materials. There are two categories of constituent materials:
matrix (polyester, vinyl ester or epoxy resin) and reinforcement.
The matrix material surrounds and supports the reinforcement materials
by maintaining their relative positions.
The reinforcements impart their special mechanical and physical
properties to enhance the matrix properties.
A synergism produces material properties unavailable
from the individual constituent materials, while the wide
variety of matrix and strengthening materials allows the
designer of the product or structure to choose an optimum
combination.
Fiberglass
Chopped Strand Mat

Emulsion or Powder Bond
300gr/m 47 kg/Roll*
450gr/m 52 kg/Roll*
600gr/m 61 kg/Roll*
CSM is the most widely used polyester and vinyl ester resin reinforcement for hand lay up. Strands of glass fiber are held together by an emulsion or powder binder to form a mat. Polyester resin dissolves the binder allowing the fibers to follow the mold contours. A typical FRP structure would contain approx. 2.5 kg resin to 1 kg CSM. CSM is not recommended to reinforce epoxy systems due to chemical incompatibility of the binder.
Glass
Woven Roving

C or E-glass
300gr/m 40 kg/Roll*
500gr/m 40 kg/Roll*
800gr/m 42 kg/Roll*
Woven Roving is used in laminating large fiberglass parts where an inexpensive, high impact, high strength reinforcement is required. It is not twisted and easier to wet out and drapes fairly well. As it cost less than fabric it is often used for boats and tanks in conjunction with CSM as a simple means of adding bulk to increase stiffness. A typical laminate use approx. 1 kg resin to 1 kg FWR. *measurements are estimated
Fiberglass
Roving

2400 TEX
16 kg/Roll
Direct roving is produced directly from tips bushing by directly winding a certain number of fiber without twist. It is compatible with polyester and vinyl ester. Its used for spray-up, filament winding and pultrusion processes or weaving.
Fiberglass
Surface Tissue
250 mt/Roll
This material is a thin fiberglass fabric which is used between the gelcoat and the reinforcing materials. Surface mat is manufactured similar in appearance to the chopped strand mat but is much finer. This surfacing veil prevents the weave patterns from bleeding through and becoming visible in the gelcoat. Also it is used to provide a resin-rich layer in liquid or chemical holding tanks, or reinforcement for layers of gelcoat.
Chopped Fiberglass
Strands
20 kg/Bag
Chopped strands are glass fiber strands that can be mixed to resin or concrete to make a dough like mixture which is extremely strong.
This coarse mixture is used to strengthen castings and reinforce fillets in difficult to laminate-sharp internal corners and other areas.
Ground Fiberglass
Milled powder
20 kg/Bag
Fiberglass grinds when mixed with resin or any body filler will improve the strength, heat resistance and reduce shrinkage. It's silane coated for good compatibility with polyesters, vinylester and epoxy. It can be mixed with vinyl ester resin to create chemical and corrosion resistant repair putty.

*(127cm wide)
Soric is a polyester non-woven material with a compression resistant hexagonal (XF, SF, LRC) or random dot-printed (TF) cell structure. These pressure-resistant cells, which are separated by channels, contain synthetic micro-spheres.
Soric SF
Soric SF is the general purpose grade, balancing resin flow and surface quality. Soric SF is therefore especially suitable for thinner laminates.
Soric XF
Soric XF maximizes weight reduction in structural core applications. Soric XF offers the fastest resin flow for the lowest resin consumption, and is therefore ideal for thicker laminates.
Soric TF
Soric TF is the ideal product for the most demanding cosmetic and surface finish requirements. Soric TF can be used as a core, but is most often used as a print blocker in infused laminates.
The cells do not absorb resin and therefore limit the total resin up-take. Since these cells are pressure resistant, they create thickness in the laminate even when pressure is applied by vacuum bag. The channels facilitate resin flow and form a pattern of cured resin with good mechanical properties and excellent bonding to the outer skins.
  • Thin core (bulker), adding stiffness, while reducing weight
  • Inter-laminar resin flow medium, eliminating the need for other (disposable) flow media
  • Mass Transit (trains, light rail, buses; interior and exterior)
  • Print blocker (liner), that meets the most demanding cosmetic and finish requirements.
Multiaxial and Specialty
Reinforcement Materials

Woven and Stitch-bonded (NCF - Non Crimp Fabrics)
Generally fabric type reinforcement surfaces can be categorized into two groups woven and stictchbonded (NCF) fabrics. The fundamental difference between two type is woven fabrics have weave formation and NCF does not. This makes it possible for NCFs to ideally transmit the forces that arise in the stress direction using targeted fiber alignment. This makes reduced component weight despite identical mechanical values or higher loads for the same component weight compared to standard reinforcement textiles (woven fabric, etc.) possible.
Mechanical Performance
of Fibers At-A-Glance
Fibers used in reinforcement fabrics has different mechanical properties and cost. Glass is the most common used fabric with moderate strength. Aramid and Carbon fiber has higher strength respectively but they can only be used with vinyl ester or epoxy resin systems.
*measurements are estimated to provide an approximate idea. Specific reinforcement product specifications should be referred before calculating composites kinetic and static design.
Woven Fabrics
Woven fabrics typically uses bidirectional weaves 0 and 90 degrees, there are several weave types most common ones are plain and twill.
Fiber woven fabrics are made up of
  • Fiberglass
  • Aramid
  • Carbon fiber
  • Hybrid combinations such as Carbon/Aramid or Aramid/Glass.
According to physical requirements of the product: glass, aramid and carbon fiber woven fabrics widely used in boat parts, hulls, decks, kayaks, surfboards, tanks, etc.

Stitch-bonded
NCF - Non Crimp Fabrics
The reinforcing surfaces are produced as stitch-bonded materials with zero elongation made of unbent fiber systems, the so-called Non Crimp Fabrics (NCFs). This makes it possible to introduce existing strengths of the fibre material directly into the end product and, thus, to achieve improved durability for the material compared to conventional processes such as with woven fabrics. A further advantage is the possibility of producing multiaxial layers with a quasi-isotropic structure.
Stitchbonded Fabrics vs. Woven Fabrics
Composite components of Non Crimp Fabrics (NCFs) make it possible to ideally transmit the forces that arise in the stress direction using targeted fiber alignment. This makes reduced component weight despite identical mechanical values or higher loads for the same component weight compared to standard reinforcement textiles (woven fabric, etc.) possible.
The basic properties of composites are dependent here on
  • Fiber type (glass, aramide, carbon)
  • The matrix system
  • The proportion of the fiber in the component
Once the component requirements are determined fiber orientation and the associated inter-laid complexes dimensioning can be so chosen as to greatly influence component properties. The reinforcement textile is a major factor. Multiaxial interlaid complexes of variable alignment and layer arrangement always has the highest mechanical characteristic values.
Compared to crimped fabrics as in e.g. woven textiles straight fibers have greater load capacity. The individual layer angularity is variable and makes force assumption in the component optimally adapted to the individual case. This gives designer two options by comparison with woven textiles: Higher mechanical characteristic values for the same weight Lower weight and less reinforcement material for the same mechanical characteristic value.
