AI Technical Summary

⚠Technical Problem

Existing glass-fiber reinforced thermoset polymer materials used in compression molding, such as SMC and BMC, are brittle and lack impact strength, limiting their application to non-impact critical parts or requiring excessive material to achieve required performance.

⚗Method used

A fiber-reinforced composite is formed by curing a prepreg of molding material on continuous fiber reinforced thermoplastic (CFRTP), using a CFRTP with a thermoplastic matrix like polyolefin or polyketone, and incorporating a nucleating agent to enhance bonding and mechanical characteristics.

🎯Benefits of technology

The composite exhibits improved mechanical properties, with a bonded CFRTP that does not delaminate, achieving a minimum bond shear strength of 1.25 ksi and bond tensile strength of 100 Ibf, enhancing impact resistance and structural integrity.

Abstract

A fiber-reinforced composite is formed by curing a prepreg having a layer of a molding material, e.g., sheet molding compound and / or bulk molding compound, on a continuous fiber reinforced thermoplastic (CFRTP). The CFRTP has a thermoplastic matrix that can bond to the molding material. The formed fiber-reinforced composite advantageously can have improved mechanical characteristics by including the CFRTP.
