Water Soluble Mandrel Materials

Water Soluble Mandrel Materials are utilized to fabricate hallow and seamless composite  structures with trapped configurations, such as:

  •   Air ducts
  •   Flaps and spoilers
  •   Stringers
  •   Tanks
  •   Cylinders
  •   Struts
  • And more!

Our Water Soluble Mandrel Materials include Solcore, Solcore 3D, SolBoard HT, TecShape and SolFoam.

Solcore 100/200
Solcore is a low cost, water removable castable tooling material, similar to plaster, capable of achieving extreme composite part design mandrel tooling requirements. With high casting fidelity and rigid green strength, Solcore is readily able to produce soluble shapes with tight tolerances and high yield. It is the ideal solutions for seamless and complex composite structures such as air ducts. The material can be formulated to withstand high temp and high pressure composites conditions found in Thermoplastics and BMI etc.
Specifications: SOLCORE 100
Density (g/ml) 0.86
Comp Strength (psi) 1500 @ 350’F
CTE (ppm – C) approx 9

How it works:

Customer sends an existing casting tool, CAD file, or composite part.

 

Soltec casts a mandel, provides a 3D mandrel print and fabricates a casting tool to cast a mandrel, or re-engineers the part to produce a CAD file in order to design and fabricate a tool and to cast a mandrel.

 
Customer produces a composite part:
  • Pre-preg, RTM, VARTM (up to 500F)
  • Autoclave up to 100psi,
  • Trim composite part on mandrel
  • Washout mandrel with pressure washer (for faster results soak mandrel for a couple hours)
SOLTEC offers Washout Service:
  • SOLTEC offers enclosed pressurized washout station to our customers
  • Customer could send composite part with mandrel to SOLTEC
  • SOLTEC to wash out the mandrel material
  • Send finished composite part back to customer
Solcore 3D

Solcore 3D is a derivation of Solcore 100 material, which has been optimized to perform on a rapid prototyping platform. Utilizing only solid CAD data, direct soluble shapes are readily produced and able to perform at advanced composite processing conditions.

Specifications: SOLCORE 3D
Density (g/ml) 0.90
Comp Strength (psi) 500 @ 350’F
CTE (ppm – C) approx 10
SolBoard HT

Ready to be used as layup tool for Thermoplastic materials or high temperature thermoset plastics such as Cyanate Esters or BMI resin systems.

Self Expandable Films, Tapes, and Coatings

Utilized to fabricate composite parts by generating pressure at an elevated temperature at the location needed (out of autoclave) or as:

  •   Pressure intensifier,
  •   Metal to composite bonding
TecFilm

TecFilm is a thin, flexible material that can be utilized to apply either focused pressure to difficult to press areas or entire surfaces which are processed between 280°F and 1300°F. It readily consolidates high temperature thermoplastics such as PEEK, PEKK, PEI, Teflon, PPS or other high performance polymers.
