WEAV3D Reinforcing Polypropylene

Improving Natural-Fiber Reinforced Polypropylene

WEAV3D Reinforcing Polypropylene

Natural-fiber reinforced thermoplastic composites have recently emerged as a lightweight, sustainable alternative to glass reinforced plastics for automotive interior applications. These materials, however, have traditionally lacked sufficient structural performance on their own to meet load and deflection requirements, necessitating the reinforcement of these materials with metallic or back-injected support structures.

This need for additional support adds a weight and cost burden that can be eliminated using our Rebar for Plastics® design approach.

New CompositesWorld Article Explores Our Technology in High-Volume Applications

We’re excited to announce we were recently featured in CompositesWorld, a leading source of news and information about fiber-reinforced composites manufacturing. The article takes a deep dive into our locally tunable composite technology—from concept to commercialization.

The article interviews our founder and CEO, Christopher Oberste, who developed the initial concept for our woven composite lattice reinforcement technology while earning his PhD at the Georgia Institute of Technology. From there, the article follows Oberste’s efforts to commercialize the technology and grow WEAV3D into the company it is today.

While the initial plan was to qualify the materials as reinforcement structures in aerospace components, Oberste and his colleagues shifted focus to the automotive and construction markets once they discovered the need for cost-effective, lightweight parts in these industries. “[Companies in these markets] told us that most of the conventional composite manufacturing processes available weren’t able to provide the volume they needed at the costs they wanted,” Oberste tells CompositesWorld.

From there, the WEAV3D technology evolved to become an enabling solution for producing high-volume composite parts at low cost. The result is our Rebar for Plastics® design concept, which now has the following commercial applications:

  • Construction: Our composite lattice enables manufacturers of utility products and construction accessories to produce economical, high-quality polymer concrete products, including trench systems.
  • Automotive: Oberste and his team have started discussions with U.S. and European tier 1 automotive suppliers and OEMs about using WEAV3D products to reinforce plastic panels in vehicles.

WEAV3D Process Overview

The patent pending WEAV3D® process is based on a woven composite lattice reinforcement called Rebar For Plastics®. Our lattice forming machines produce custom lattice structures from unidirectional, fiber-reinforced composite tapes. The composite lattices are then overmolded into a finished structural component using conventional molding processes.

By tuning the weave density, tape materials and number of layers in the lattice preform, we can locally tune a part’s performance to meet application-specific targets, all while reducing costs by 30 to 50% versus traditional composites.

WEAV3D Applications

WEAV3D® technology reduces waste, cycle time and material handling costs—enabling new innovations in the automotive and construction industries. For example, our patent pending reinforcement materials let you lightweight automotive interior and exterior components, including instrument and body panels—increasing vehicle fuel economy and extending EV range.

Our composite lattice is also an alternative solution to traditional steel wire cage, rebar and sheet molding compound (SMC) reinforcement for precast polymer concrete. It offers a lightweight, completely non-metallic reinforcement material that provides high levels of durability and strength.

WEAV3D Nonmetallic Alternative to Steel Rebar

New Oldcastle Cable Trench Overcomes Challenges of Steel Reinforcement, Thanks to WEAV3D Composites

WEAV3D Nonmetallic Alternative to Steel Rebar

Cable trenches play an important role in managing and distributing cables and wires in utility, rail and power applications. Oldcastle, a leading provider of building materials, supplies these durable components in the form of its polymer-based concrete trench systems, which use a steel wire cage to reinforce the material. While they have their advantages, polymer concrete systems don’t adhesively bond to the steel—instead relying purely on the mechanical interface between the materials.

Our composite lattice has allowed Oldcastle to produce an economical, yet high-quality cable trench without the failure modes of polymer concrete systems. The result of our collaboration is a completely non-metallic cable trench system that offers many advantages. Read our recent application note to learn more.

WEAV3D Brings Its Composite Production Technology to Upcoming Plug and Play Program


Norcross, GA, October 02, 2019 — WEAV3D, an innovator in composite materials, manufacturing processes and processing equipment, was recently selected by Plug and Play to participate in its Winter 2019 Mobility accelerator program, which focuses on emerging automotive technologies. WEAV3D returns to Plug and Play after graduating from its Spring 2019 Materials and Packaging program.

Designed for high volume production, WEAV3D’s composite forming machine processes continuous, fiber-reinforced thermoplastic tapes, allowing users to vary weave pattern, lattice density and tape-type and enabling complete control over part cost, strength, and stiffness. Lattice structures are combined with injection molding or thermoforming processes—creating lightweight structural composites that cost up to 50 percent less than composites formed using traditional methods.

WEAV3D’s structural composite technology is an excellent fit for the automotive industry, as it reduces weight while maintaining high-strength components in vehicles. While this area has been the company’s initial focus, the technology applies more broadly to other structural composites applications as well.

Plug and Play’s three-month business development programs—which also include Materials and Packaging, Energy, Sustainability, Construction and more—consist of various workshops, mentor meetings and networking events. As part of the Winter 2019 batch, WEAV3D will graduate this December at the Winter Summit, where all 130 startups will make onstage pitches in front of over 500 investors and other industry leaders.
