· Kevlar 49/Epoxy· Aramid UD· AFRP

Aramid fiber-reinforced plastic (AFRP) combining DuPont Kevlar 49 aramid fibers in a unidirectional 0° orientation with epoxy matrix, processed as prepreg and cured at 120°C. This material is engineered for applications demanding high specific strength, excellent impact resistance, and low density in a fiber-dominated, load-aligned configuration. Industries rely on it for ballistic protection, aerospace structures, and high-performance sporting goods where weight savings and damage tolerance outweigh the cost premium relative to glass or carbon fiber composites.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
