Understanding Composite Blind Rivets
Understanding Composite Blind Rivets
Composite Blind Rivets represent a fastening solution specifically engineered for composite materials such as FRP, fibreglass panels, and composite structures. By optimising the flange dimensions and rear expansion structure, they achieve more uniform load distribution. This ensures connection strength while minimising damage to the composite surface layer.
Differences
How do they differ from standard blind rivets?
- Larger flange or bearing surface to reduce pressure per unit area
- Optimised backside expansion profile creating a more stable support surface
- More controllable clamping force, minimising compressive damage to composite fibre layers
- Better suited for FRP and composite structural connections
Best Types
Which Composite Blind Rivet Type Is Most Recommended？
For composite material (FRP/composite panels) connections, we most highly recommend the use of HuckLok® Structural Blind Rivets. Classified as a bulbing structural rivet, it creates a large-area support footprint at the blind end, significantly reducing interlaminar stress within the composite material. This represents a highly reliable solution currently employed in engineering applications.
Specifications
Key Performance Specifications of HuckLok Rivets
for Composite Panel Applications
| Parameter | Typical Value (Example HKLP-R8-7) |
|---|---|
| Rivet Diameter | 1/4 in (6.4 mm) |
| Grip Range | 0.187 – 0.437 in |
| Shear Strength | 3500 lbf (≈15.6 kN) |
| Tensile Strength | 1900 lbf (≈8.45 kN) |
| Blind-side footprint | Large bulbing footprint |
| Locking mechanism | Double mechanical locking |
From an engineering perspective, HuckLok’s structural design precisely addresses the three core issues of composite panels:
① Pull-through prevention: The blind-end bulbing structure creates a large support surface, effectively distributing loads.
② Reduced interlaminar shear stress: Load distribution across a larger area minimises interlaminar shear stress within the composite material.
③ Structural locking: HuckLok employs double-locking mechanical retention, ensuring the mandrel remains securely locked within the rivet body.
Why HuckLok is Suited for Composite Panels
1️⃣ Large blind-side footprint
The bulb structure creates a substantial bearing surface on the reverse side, preventing localised damage to the composite laminate.
2️⃣ Double-locking structural joint
The mandrel is mechanically locked within the rivet, ensuring long-term structural integrity.
3️⃣ Wide grip range
The composite material exhibits significant thickness variation (panel + core + skin), and the wide clamping range reduces the number of SKUs required.
4️⃣ High shear strength structural joint
Structural-grade blind rivets can withstand high shear loads, making them suitable for lightweight structural components.
