HybridCore V2 vs. Fiberglass Skateboard Decks

Some brands — notably in the snowboard-crossover and longboard space — build decks with fiberglass reinforcement as the primary composite material. Fiberglass is cheaper than carbon fiber and easier to work with, which makes it a common choice for entry-level composite construction. This page explains the difference between a fiberglass-primary deck and the HybridCore V2.

What Is a Fiberglass Skateboard Deck?

Fiberglass-reinforced decks typically sandwich one or two layers of woven fiberglass between maple veneers — similar to DBX construction but using glass fiber instead of carbon. Some constructions use fiberglass as the top and bottom shells, replacing the outer maple veneers entirely.

Common in: Lib Tech skate decks, some Never Summer crossover decks, longboard constructions, and various "composite" decks from smaller brands.

The result is a deck with better impact resistance than pure maple, some added stiffness, and improved delamination resistance. Fiberglass is a genuine improvement over maple. It is not the same as carbon fiber.

Carbon Fiber vs. Fiberglass — The Material Difference

This is the core of the comparison:

Stiffness (Modulus) Carbon fiber (T300 grade) has a tensile modulus of approximately 230 GPa. Standard E-glass fiberglass has a tensile modulus of approximately 70 GPa. Carbon fiber is roughly 3× stiffer than fiberglass per unit of material.

In practical terms: a carbon fiber outer shell provides significantly more structural stiffness and torsional control than an equivalent fiberglass shell at the same thickness and weight.

Weight Carbon fiber is lighter than fiberglass at equivalent stiffness. To achieve the same structural performance as a thin carbon shell, a fiberglass shell needs to be thicker — which adds weight.

Torsional Control Both carbon and fiberglass can be oriented at ±45° for torsional control. However, carbon fiber's higher modulus means the ±45° orientation is dramatically more effective in carbon than in fiberglass. The HybridCore V2's ±45° carbon outer shells deliver torsional lock that a fiberglass equivalent cannot match at the same thickness.

Cost Fiberglass is significantly cheaper than carbon fiber — roughly 5–10× less expensive by weight. This is why fiberglass constructions are more common in mid-range composite decks.

How HybridCore V2 Uses Fiberglass

The V2 does not use fiberglass as a structural shell. Fiberglass appears in the V2 as a dedicated bonding layer between the bamboo core and the surrounding maple structural layers.

This is an engineering-specific use: bamboo and maple have different surface properties and bond differently than maple-to-maple. The fiberglass bonding layer provides aerospace-grade adhesion that prevents delamination under impact — a problem common in bamboo-containing constructions without this layer.

In the V2, fiberglass solves a specific bonding problem. Carbon fiber handles structural performance.

Which Should You Choose?

If you are comparing a fiberglass deck to the HybridCore V2, the V2 wins on structural performance in every measurable category — stiffness, torsional control, and weight efficiency. The only advantage fiberglass-primary decks have is price.

The HybridCore V2 uses both materials correctly: carbon fiber for structural performance, fiberglass for bonding. That is what "engineered composite" means versus "reinforced maple."
