Parameter
SALTWATER GRADE PREPREG CONSTRUCTION
High-Strength Corrosion-Resistant Carbon Fiber Surfboard
Epoxy-based carbon fiber prepreg with PVC or EPS foam core, manufactured via vacuum bagging or compression molding. Tensile strength of face sheet 800-950 MPa, flexural modulus 55-70 GPa. Corrosion resistance tested per ASTM B117: 1,000 hours salt spray exposure without surface pitting or interlayer delamination. Seawater absorption less than or equal to 0.12 percent after 30 days immersion. Board weight range 2.2-3.5 kg depending on volume (28L to 45L).
Flexural strength800-950 MPa
Salt spray resistance1000h ASTM B117
Core optionsEPS / PVC / PU

Corrosion and environmental performance
  • Saltwater immersion: Weight gain less than or equal to 0.12 percent after 720 hours in synthetic seawater (35 ppt salinity, 40 degrees Celsius).
  • UV resistance: Clear coat retains 92 percent gloss after 500 hours QUV-A (ASTM G154).
  • Galvanic isolation: No direct metal contact required; carbon fiber surface shows no galvanic corrosion when paired with SS316 leash plugs.
  • Chemical exposure: Unaffected by sunscreen, diesel, or cleaning agents (tested per ISO 175).

Structural and layup specification
Fiber architecture3K twill / unidirectional / biaxial ±45 degrees
Resin systemEpoxy (Tg 110-120 degrees Celsius), UV additive
Core densityEPS: 25-35 kg/m3 | PVC: 60-80 kg/m3
Fiber volume fraction52 to 58 percent
Skin thickness0.8 to 1.5 mm (bottom and deck)
01
Impact toughness
Charpy impact strength 120-150 kJ/m2 at 23 degrees Celsius. Rail impact resistance tested per drop weight method (5 kg from 0.5 m) with no puncture or visible crack propagation.
02
Flexural fatigue
Three-point bending fatigue: 200,000 cycles at 40 percent ultimate load without stiffness degradation exceeding 8 percent.
03
Buoyancy and flex pattern
Volume range 26-50L, rocker adjustable via stringer integration. Longitudinal flex 4-8 mm per 50 kg load (static).
Design and customization options
- Tail shapes: squash, swallow, round, pin tail
- Stringer options: carbon sandwich, wood veneer, or no stringer
- Leash plug: SS316 molded-in with 6 mm slot
- Fins: FCS II or Futures box compatibility
- Deck traction: embossed carbon texture or EVA pad pre-installed
Care and handling for seawater environment
- Rinse with fresh water after each session; salt residue does not damage carbon but may abrade clear coat.
- Avoid direct sunlight storage above 60 degrees Celsius (vehicle interior) — resin Tg exceeds 110 degrees Celsius, but UV clear coat lifespan reduces above 50 degrees Celsius.
- Repair kit: epoxy-based filler for ding repair; polyester resin not compatible with epoxy matrix.
- Transport protection: edge guard recommended for rail and nose and tail sections.
[w] Application range and wave conditions
Small wave grovelers (0 to 1.5 m) Step-up boards (1.5 to 3 m) Tropical reef breaks (high UV and abrasion) Cold water surfing (0 to 10 degrees Celsius, no brittleness) Sup foil conversion boards
Maximum rider weight per volume
Volume (L) x 1.1 equals suggested max rider weight (kg). 30L board supports up to 85 kg for intermediate surfing.
Repairability of carbon skin
Surface cracks filled with epoxy and cabosil. Structural delamination requires wet layup carbon patch (two layers twill).
Flex tuning for different wave types
Stiffer layup (more zero-degree unidirectional) for hollow waves; softer flex (more plus/minus 45 degrees) for small mushy waves. Custom layup available.
Lead time for custom orders
10 to 14 business days for standard shape; 21 to 28 days for full custom rocker, foil, and layup.
i Test data based on 2.2 mm total skin thickness (deck plus bottom) with EPS core 35 kg/m3. Salt spray performed per ASTM B117 continuous exposure. Warranty: 2 years against delamination or core crush under normal use.
