Mallinda Makes REversible Thermoset Prepreg Laminates For high throughput composite part production

Mallinda's patented resin system eliminates the slow infusion and long curing cycles of today's resins; enabling compression-molding of products in just seconds for high-throughput, high-volume production of structural composites. In addition, our prepreg is pre-cured, shelf-stable, and requires no refrigeration for transport and storage.

Mallinda's prepreg resin is a disruptive platform technology that allows rapid (< 1 minute) compression molding of fully cured thermoset composite parts. It is designed for carbon fiber composite production using rapid compression molding techniques analogous to sheet metal stamping. In addition, Mallinda’s resin can be depolymerized in solution for a cradle-to-cradle, energy-neutral system for the recovery of resin and woven/full-length fiber.

Recylable Advanced Carbon Fiber Reinforced Composites

Mallinda has developed a completely closed loop system for the recovery of both polymer and carbon fiber from CFRC end-of-life products and scrap materials. Our patent-pending recycling process takes advantage of the reversible chemistry of our material, and generates no excess waste, and uses almost no energy. Both the recovered carbon fiber and the recovered resin can be reused to make fresh composite materials. No longer will CFRCs end up in landfills.


A Range of Processing Temperatures & Range of Mechanical Properties

Mallinda’s resin can be formulated to have a low molding temperature range. Our resin can be molded at temperatures as low as ~20 ̊C and as high as ~150 ̊C, depending on formulation. In some applications, this feature has the benefit of allowing end-users to custom mold our resin or composites derived therefrom, to suit the end user’s needs without the use of expensive and massive industrial equipment.

In addition, Mallinda's material can be formulated to have a range of mechanical properties - from elastomeric to crystalline.

Mallinda is currently developing its material to meet the specs of the automotive market.


Short Cycle Times & Repairability

Due to the malleable nature of our resin, fully cured composite sheets can be perfectly welded together in less than 1 minute.  This means that Mallinda’s composites can be substituted for prepreg sheet, but can be stored at room temperature (or higher) indefinitely, and do not require a curing step.  Only heat and pressure are required to mold the cured sheets into shape, and similarly, heat and pressure treatment can heal or repair damage (such as impact damage) in the material.


Reprocessable

Mallinda’s resin may be recycled many times over. The plastic may be ground into a powder and reformed into new shapes with heat and pressure. This both increases the input lifetime vis-a-vis recycling and reduces the energy required during repurposing.

In addition, Mallinda's ability to implement solid state thermoforming could revolutionize production of powder-based composite materials.


Environmentally Friendly Synthesis

No heavy metal catalysts or organic solvents are used in making our resin. And the only byproduct in the chemical production is water.

What does this mean?

It means that we have created one of the most user-friendly plastic materials to date.
